Introduction

Reading scientific literature is a critical part of conceiving of and executing a successful advanced science project. The How to Read a Scientific Paper guide can help you get the most out of each paper you read—first, of course, you have to actually get your hands on the paper! That's where this guide comes in. Below you'll find tips and resources for both searching for and acquiring free copies of scientific papers to read.

Academic Search Engines: Resources for Finding Science Paper Citations

When you start your background research, one of the early steps is finding and reading the scientific literature related to your science project (see the Roadmap: How to Get Started On an Advanced Science Project article for more details on project steps). Mentors are a great resource for recommendations about which scientific papers are critical for you to read and you should definitely ask your mentor, or another expert in the field, for advice. But there'll also be times when your mentor is busy or isn't up-to-date on a particular experimental method, in which case, you'll need to be proactive and hunt for papers on your own. It turns out that just plugging search terms into a regular search engine, like Google, Yahoo, or MSN, isn't very effective. The pages you get back will be a wide mixture of websites, and very few will be links to peer-reviewed scientific papers. To find scientific literature, the best thing to use is an academic search engine.
There are many different academic search engines. Some focus on a single discipline, while others have citations from multiple fields. There are a handful of free, publicly available academic search engines that can be accessed online; some of these are listed in Table 1, below. The remainder, like the ISI Web of Science, are subscription-based. Universities and colleges often subscribe to academic search engines. If you can't find what you need using a free search engine, you may be able to access these resources from computers in a university or college library. Consult the school's library webpage, or call the library directly, to find out to which academic search engines they subscribe to and whether or not you'd be allowed into the library to access them.

Table 1: This table provides a list of free, online academic search engines for various science disciplines.

Academic Search Engine	URL	Disciplines	Help Files
Google Scholar	scholar.google.com	All	scholar.google.com/intl/en/scholar/help.html
ScienceDirect	http://www.sciencedirect.com/science/search	All	NA
Pubmed	www.ncbi.nlm.nih.gov/pubmed	Life sciences	www.nlm.nih.gov/bsd/disted/pubmedtutorial
IEEE Xplore	ieeexplore.ieee.org/Xplore/guesthome.jsp	Electronics, Electrical engineering, Computer science	NA
National Agricultural Library (AGRICOLA)	agricola.nal.usda.gov	Agriculture	agricola.nal.usda.gov/help/quicksearch.html
Education Resources Information Center (ERIC)	eric.ed.gov	Education	NA

Here are a few tips to help you get started with the academic search engines:

• Each search engine works slightly differently, so it's worth taking the time to read any available help pages to figure out the best way to use each one.
• When you're beginning your literature search, try several different key words, both alone and in combination. Then, as you view the results, you can narrow your focus and figure out which key words best describe the kinds of papers in which you are interested.
• As you read the literature, go back and try additional searches using the jargon and terms you learn while reading.

Note: The results of academic search engines come in the form of an abstract, which you can read to determine if the paper is relevant to your science project, as well as a full citation (author, journal title, volume, page numbers, year, etc.) so that you can find a physical copy of the paper. Search engines do not necessarily contain the full text of the paper for you to read. A few, like PubMed, do provide links to free online versions of the paper, when one is available. Read on for help finding the full paper.

How to Get a Copy of a Scientific Paper

Once you've found the citation for a paper that is relevant to your advanced science project, the next step is actually getting a copy so that you can read it. As mentioned above, some search engines provide links to free online versions of the paper, if one exists. If the search engine doesn't, or if you got the citation somewhere else, like the bibliography of another science paper you were reading, there are several ways to find copies.
Searching for Newer Papers (published during Internet era)

• Check the library of a local college or university. Academic institutions, like colleges and universities, often subscribe to many scientific journals. Some of these libraries are free to the public. Contact the library, or look at their website, to see if you may use their resources and if they subscribe to the journals in which you're interested. Often, the library's catalog of holdings is online and publicly searchable.
  1. Note: If you do go to a university or college library to photocopy or print journal articles, make sure to bring plenty of change with you, because they won't have any!
• Look for a free online version. Try searching for the full title of the paper in a regular search engine like Google, Yahoo, or MSN. The paper may come up multiple times, and one of those might be a free, downloadable copy. So, if the first link isn't downloadable, try another.
• Go directly to the online homepage of the journal in which the paper was published. Some scientific journals are "open-source," meaning that their content is always free online to the public. Others are free online (often after registering with the website) if the paper was published more than a year ago. The Directory of Open Access Journals is also a good place to check to see which journals are free in your field of interest. The website lists journals by subject, as well as by title.
• Search directly for the homepage of the first or last author of the paper and see if he or she has a PDF of the paper on his or her website. If so, you can download it directly from there. Generally it is only worth looking up the first author (the one who contributed the most to the paper) or the last author (usually the professor in whose lab the work was done and who supervised the science project).
• Look for the paper (using the title or authors) in a science database, like those listed below, in Table 2. These databases contain free, full-text versions of scientific papers, as well as other relevant information, like publicly accessible data sets.

Table 2: List of databases containing free, full-text scientific papers and data sets.

Database	URL	Disciplines
NASA Scientific and Technical Information (STI)	www.sti.nasa.gov/STI-public-homepage.html	Aerospace
SOA/NASA Astrophysics Data System	adswww.harvard.edu/	Astronomy, physics
arXiv	arxiv.org/	Physics, Mathematics, Computer science, Quantitative biology, Quantitative finance and statistics
CiteSeerX	citeseerx.ist.psu.edu/	Computer science
Public Library of Science (PLOS)	https://www.plos.org/	Life sciences
High Wire Press	highwire.stanford.edu/lists/freeart.dtl	Life sciences

• Purchase a copy. Depending on the science magazine publisher, you may also come across offers for purchasing a copy of the paper. This is an expensive option, particularly if you have multiple papers you'd like to read; try some of the other searching methods first

Searching for Older Papers (published pre-Internet era)
Even with all of the above searching methods, you may not be able to find a free copy of the paper online. This is particularly true for older science papers, which were published before online content became routine. In these cases, there are additional ways to get the paper at no or minimal cost.

• Contact the author via email. As mentioned above, the first and last authors are your best bets. Briefly explain your situation and request a copy of the paper directly from him or her. If you do this, make sure to be polite and brief in your email.
• Check the library of a local college or university. Academic institutions, like colleges and universities, often subscribe to many scientific journals. Some of these libraries are free to the public. Contact the library, or look at their website, to see if you may use their resources and if they subscribe to the journals in which you're interested. Often, the library's catalog of holdings is online and publicly searchable.
  1. Note: If you do go to a university or college library to photocopy or print journal articles, make sure to bring plenty of change with you, because they won't have any!
• Contact your mentor and ask if he or she can help you acquire a copy of the paper. Use this as a last resort though, because you may find that your request falls pretty far down on a mentor's lengthy to-do list.

DIFERENT WAYS TO DOWNLOAD FREE RESEARCH PAPERS

5 Ways to Download Research Papers Free Legally

Research publication is an expensive field, both for researcher and reader. Most of the scientific studies are behind the paywall when the researcher refuses to pay the publication fee for open-access publication.
Payment-asking publishers frustrate only the early researchers who don’t have Institutional e-library access. There are many illegal ways to download research papers. But for me, like many others, it’s no-nothing.
In this post, I’m going to share the Legal ways to download Research Papers for Free. No more guilt of using pirated content in your content.

Education For All

Learn and Become Educated

According to modern defination, an educated person should have to learn reading, writing and simple methematical problems, So he can known as an educated personality.

For the purpose to produce educated personalities in society there are many projects running in pakistan. The main purpose is to make the individual educated according to defination. 

BUT EDUCATION IS NOT ONLY TO LEARN READING, WRITING AND SOLVING METHEMATICAL PROBLEMS. THE LEARNED SKILLS ARE ALSO A TYPE OF EDUCATION.

 The main issue is to develop skilled power and to engage that power to produce products and services.

So , I call for each and every person to learn and earn

Because EDUCATIO IS THE RIGHT OF EVERY INDIVIDUAL OF HUMAN BEING

Last week the Education for AllGlobal Monitoring Report was launched. It looked at how 164 countries across the world had performed after committing to six education goals in the ‘Education for All: Meeting our Collective Commitments’ framework at the World Education Forum in Dakar, Senegal, in the year 2000. On Wednesday, 22nd April, 2015, the review report was launched in Islamabad and an “Education for All 2015 National Review” summed up Pakistan’s part of the tale.

Where to Get Free Research Paper

Where to get research papers for free

Last update  May, 5th, 2016

After the post about ebooks, I have thought you may be interested on academic papers too and here I am! :) THANKS for your contributions to this post!

On the subject education, there is also a new post about the free university courses you can attend online, for free!!!

Anyway, if you are a PhD student or a researcher you need to download and study other people's scientific works. For most journals (the most important ones) your institution should have already a subscription.

However you'll probably have already experienced that sometimes, you need a paper you cannot download through your institution, pretty annoying eh?

So... how can you solve this problem?

Where can you download research papers for free?

Where to find free scientific journal articles?

How to get that f*ck*ng full-text pdf?

Are there alternatives to sci-hub?

Yes, just read below!

By the way, is sci-hub down? NO, once again, just read below!


I will list you several options to address this problem. At least one of them will be suitable for you. I'm 99.9999% sure! ;)

1) Ask to the librarian of your university. He/She knows for sure whom ask the paper you are looking for.

2) Look for the draft version of the published paper.
A good starting point is the Cornell University Library http://arxiv.org/ where many researchers put their papers before they are accepted on some journal.
Very often the authors update the file on arxiv.org even after the acceptance.

3) Search NOT on google.com but on https://scholar.google.com instead.
Insert the reference of your paper (Author(s), journal, volume, page), perform the search and when you find it, click "show all versions".
In this way you can check if the pdf of the paper you are intersted in is available somewhere over the web.

4) Check if your Journal is listed here http://highwire.stanford.edu/lists/freeart.dtl

5) Ask the authors and/or visit their homepages. Or simply ask the "Boss", usually the last author.
Clearly it doesn't work if the paper is too old...

6) http://sci-hub.org and its mirrors

•  http://sci-hub.io 
•  http://sci-hub.cc 
•  http://sci-hub.bz
• 31.184.194.81 
• and .. .it you use the tor browser  http://scihub22266oqcxt.onion/

So if sci-hub.org is down, try the mirrors! And if the mirrors are also down... well there are still the other options!

This is the most powerful option, the only one that NEVER fails but it is also completely illegal.
I mean, it simply doesn't look like something legal, but I could be wrong...  anyway you are warned!
NOTE: Sometimes its servers are down.
This should be temporary and anyway you can still refer to http://libgen.org/scimag/



*** UPDATE #3 on sci-hub from another reader below ***
Apparently, Russian proxies are no-longer required to use sci-hub.org
or sci-hub.io  or   sci-hub.cc

*** UPDATE #2 on sci-hub from another reader below ***
It works with the Russian proxies, but sometimes you'll have to keep trying, which means refreshing your browser or trying again a few minutes later until it works. 

*** UPDATE #1 on sci-hub from a reader below  ***
Sci-hub is not down, actually. It's just restricted to users inside Russia, which means that you'll be able to access it if you use a Russian proxy. A list of russian proxys: http://www.proxynova.com/proxy-server-list/country-ru/
alternatively you can setup a vpn (for example with Astrill) with access to russian proxies. 


7) http://jxplore.com/ this seems to be the best sci-hub.org alternative.


8) http://booksc.org/
Similar to sci-hub but it works only with "popular" scientific papers. And it's illegal.. probably.

9) http://www.freefullpdf.com/
Similar to sci-hub, it could take some time to load.


10) Already known from the ebook post on this blog:
bookzz.org
bookfi.org

Free, free subscription, daily limit


11)  https://www.reddit.com/r/Scholar/
At the column at the left of the above page there are listed sites with open access journals

12) Directory of Open Access Journals
 https://doaj.org/


13) PLOS one

http://www.plosone.org/home.action


14) Alphabetical List of Open Access Journals in Ancient Studies
 http://ancientworldonline.blogspot.com.cy/2012/07/alphabetical-list-of-open-access.html


15) I almost forgot! Ask a friend who works at a University, better if he/she is Finnish! This is not a joke! Finnish people working at Universities have access to many on-line journals!

16) As pointed by a reader below... Facebook can also be a valuable resource!


To use it you have simply to copy the link of the paper, just the link you find on the official page of the journal. YES, the one that, if clicked, prompt you immediately on the page where you are asked for the login and/or the money!

In short, http://sci-hub.org is for scientific papers what library.nu was for books and for this,  it will likely experience the same end.

If you CANNOT access sci-hub in your country, just try to install the Firefox and Chrome add-on proxmate.


Note...
Probably, if your institution doesn't have the subscription for the journal you want, probably that journal (and consequently the paper you are interested in), is not that important in your research field.

Another possibility could be that your library has not so much money and in this case other solutions are (partially) justified...

Good luck!

Beyond being the founder of Sci-Hub, the world’s largest pirate site for academic papers, and risking arrest as a result, Alexandra Elbakyan is a typical science graduate student: idealistic, hard-working, and relatively poor. In 1988, when Elbakyan was born in Kazakhstan, the Soviet Union was just beginning to crumble. Books about dinosaurs and evolution fascinated her early on. “I also remember reading Soviet science books that provided scientific explanations for miraculous events thought previously to be produced by gods or magic.” She was hooked.
At university in the Kazakh capital, she discovered a knack for computer hacking. It appealed to her because “unlike higher programming languages that are created by people and are volatile,” making and breaking computer security systems requires a deeper knowledge of mathematics and the primitive “assembly language” that computers use to move information.

Journal paywalls are an example of something that works in the reverse direction, making communication less open and efficient.

• It's a Sci-Hub world data set
  Data set and details on Sci-Hub server

Like so many of Kazakhstan’s brightest, Elbakyan left the country to pursue her dreams. First she worked in Moscow in computer security for a year, and then she used the earnings to launch herself to the University of Freiburg in Germany in 2010, where she joined a brain-computer interface project. She was lured by the possibility that such an interface could one day translate the thought content from one mind and upload it to another. But the work fell short of her dreams. “The lab activity was spiritless,” she says. “There was no feeling of pursuing a higher goal.”
Elbakyan did find a community of like-minded researchers in transhumanism, a lofty field that encompasses not just neuroscience and computer technology but also philosophy and even speculative fiction about the future of humanity. She discovered a transhumanism conference in the United States and set her heart on attending, but she struggled to get a U.S. visa. She was rejected the first time and only barely made it to the conference. With the remainder of her summer visa, she did a research internship at Georgia Institute of Technology in Atlanta. When she got back to Kazakhstan, frustration with the barriers that scientists face would soon lead her to create Sci-Hub—an awe-inspiring act of altruism or a massive criminal enterprise, depending on whom you ask.
Publisher paywalls are the bane of scientists and students in Kazakhstan, she says, and the existing solution was cumbersome: Post a request on Twitter to #IcanhazPDF with your email address. Eventually, a generous researcher at some university with access to the journal will send you the paper.
What was needed, she decided, was a system that allowed that paper to be shared—with absolutely everyone. She had the computer skills—and contacts with other pirate websites—to make that happen, and so Sci-Hub was born. Elbakyan sees the site as a natural extension of her dream of helping humans share good ideas. “Journal paywalls are an example of something that works in the reverse direction,” she says, “making communication less open and efficient.”
Running a pirate site and being sued for what is likely to be millions of dollars in damages hasn’t stopped Elbakyan from pursuing an academic career. Her neuroscience research is on hold, but she has enrolled in a history of science master’s program at a “small private university” in an undisclosed location. Appropriately enough, her thesis focuses on scientific communication. “I perceive Sci-Hub as a practical side of my research.”

Digital piracy is not all about movies and music—pretty much anything that people feel is unfairly priced will find its way online in large numbers. Even academic papers.

In October 2015, a New York district court ruled in favor of the academic publisher Elsevier, which had accused Sci-Hub, a website that offers pirated versions of academic papers, of copyright violation. That decision allowed authorities to take down the site’s domain name, sci-hub.org.

Suspending a domain name does not delete a website forever, though, it just prevents visitors from knowing where exactly to find it. It’s trivial enough to relaunch the same site under another domain, as Sci-Hub did, setting up as sci-hub.io. Now knowledge of the new domain has spread far and wide, with mentions of it showing up across social networks like Reddit and Hacker News, and with coverage in publications like Big Think and The Atlantic (our sister publication).

Sci-Hub’s tagline is “to remove all barriers in the way of science.” It was created by Alexandra Elbakyan, a neuroscience researcher from Kazakhstan, and is effectively an automated version of the #icanhazpdf hashtag. Most academic papers are behind some kind of paywall, coming out to around $30 per paper, according to one estimate. In the manual way of getting around this, someone tweets a link to a paper along with their email address and the hashtag #icanhazpdf. Someone else, who has access to the paper, perhaps through a subscription or their university, then downloads and emails the paper to them.

Sci-Hub, on the other hand, takes a link to a paper and automatically tries credentials for various universities until it manages to gain access to the paper, retrieving the PDF. This method gives it access to more information than any individual researcher or institution, and Sci-Hub estimates its total access at 47 million papers.

The new domain will be hard for a US-based lawsuit, like Elsevier’s from last year, to shut down. The US only has jurisdiction over registrars based in the US, such as .com, .net, and .org. The trendy .io domain is actually registered to the British Indian Ocean Territory, meaning the UK would have to act, as happened with PopcornTime.io, the Netflix-for-pirates.

But as The Atlantic points out, Sci-Hub will be able to survive any number of domain seizures thanks to its existence on the “dark web.” Accessing the site in this way, through the distributed Tor network, does not involve any centralized registry, meaning there is no single entity that authorities can shut down.

The main beneficiaries of Sci-Hub are outside of the US, like the site’s creator herself. The traffic figures from Alexa.com, though only a crude estimate, list users from China, Iran, India, Brazil, and Russia as the top visitors to sci-hub.io, with the US outside the top five. While even Harvard has said it can’t afford the steep prices of some publishers, most American universities offer relatively robust access, and researchers may be able to afford the $30 or so it usually costs to purchase a paper.

“For me, even the purchase of one such article would be a financial setback,” Alexandra told Russia Today via email. “So I had to go about acquiring all the articles by pirate means.”
Remember me in prayers.

With the increasing demand for research in education, and progress in research every person need to get updated knowledge. To get information every one use internet libraries and research journals to upgrade his knowledge. But there are some barriers to obtain articles and research paper. Some universities provide free access to their students. But after completing his education standered all students lose their access. But their research work and knowledge up-gradation don't stop. So they face problems while accessing many journals.

Sci-Hub is an online repository of over 51,000,000^[1] scientific academic papers and articles,^[2] available through its website. New papers are uploaded daily after accessing them through educational institutions.^[3] Founded by Alexandra Elbakyan from Kazakhstan in 2011, it began as a reaction to the high cost of research papers behind paywalls, typically US$30 each when bought on a per-paper basis.^[4] Academic publisher Elsevier has in 2015 filed a legal complaint in New York City alleging copyright infringement by Sci-Hub.^[5]
The Sci-Hub project started running on 5 September 2011,^[9] founded by Alexandra Elbakyan, a software developer and neurotechnology researcher from Kazakhstan,^[10] with the goal to increase the spread of knowledge by allowing more people to access paywalled content.^[11] The project's original domain name, Sci-Hub.org, was suspended in November 2015 due to a court order.^[12] The project resurfaced again that same month under a .io domain.^[13]
The site has become very popular in developing countries including India, Indonesia,^[14] Pakistan, Iran, China, Russia and Brazil.^[15] As of early 2016, data released by Elbakyan shows that developed countries also use Sci-Hub, as a large proportion of the downloads comes from the US and countries inside the European Union.^[7] Providing access to research for less privileged institutions and countries has been Elbakyan's express goal in creating the site, stating that she similarly shared papers without permission when she did research at a Kazakhstan university, given the need to skim hundreds of papers.^[16]
Sci-Hub is the first known website to provide automatic and free access to paywalled academic papers on a massive scale.^[17] Before Sci-Hub people used to request and share research papers manually by direct email to paper authors or other academics^[17] or by requesting them via online research forums^[18] or social networks, like the #ICanHazPDF Twitter tag.^[19]

Sci-Hub provides readers with articles without requiring a subscription or payment.^[20] In February 2016, the Sci-Hub website claimed to serve over 200,000 requests per day.^[21][22][7] According to Elbakyan, the website had an average of 80,000 visitors per day before its original domain, Sci-Hub.org, was blocked.^[2]
The site gets papers by passing through publishers' paywalls using a collection of credentials (user IDs and passwords) belonging to people at educational institutions with legitimate access to the publishers' sites. According to article published in Science, Elbakyan said that many anonymous academics from around the world have donated their credentials.^[7] Publishers have claimed that Sci-hub relies on credentials obtained by phishing.^[7] Sci-hub has credentials to access papers published at JSTOR, Springer, Sage, and Elsevier, among others.^[23] As of 2013, Sci-Hub started collaborating with Library Genesis, a repository of educational books and documents hosted in Russia.^[24] If the requested paper was available there, it was deployed to the user. If a paper was not previously available at LibGen, Sci-Hub would download it and share a copy of the document with LibGen for future use.^[20] Today, Sci-Hub relies on a distributed network of repositories to store and retrieve research papers.^{[citation needed]} The site's operation is financed by user donations^[7][25] of the cryptocurrency bitcoin.^[26]
In 2016 Sci-Hub's .io domain was taken offline after a complaint from Elsevier was directed to the site's Chinese registrar, Now.cn. Despite the takedown by the registrar, Sci-Hub remains reachable via alternate domains, IP address and a .onion Tor Hidden Service scihub22266oqcxt.onion; the latter of which TorrentFreak states is "pretty much immune" to take down requests.^[1][27]
