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
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!

Thanks :)

Very interesting article ,
please can you explain me how to use http://sci-hub.org ?

Anonymous said...

Dude, you have to insert in sci-hub the URL link of the PDF you are interested in.

mathew said...

hi can you all help me locate these three articles? i do not know how to get the url for these articles. please help

Czerwik, S: Nonlinear set-valued contraction mappings in b-metric spaces. Atti Sem Mat Fis Univ Modena. 46(2), 263–276 (1998)

please help. thanks

eddie said...

My suggestion is to contact the authors directly, since these papers are very specific, the authors (my guess) will be probably very happy to send you at least some draft versions :)

Try BookSC.org

eddie said...

Thanks!

Sci-hub.org is down :(

eddie said...

it seems so.

Sci-hub.org is not working now. how to free download the research papers pl help. is there any links?

Anonymous said...

libgen.org is made by the same guys who maintain scihub.org. I think Sci-hub is down because they are revamping their servers or something. You can search for and get old papers on libgen, very easily, just be sure to enter the exact title and then click the DOI link to get the paper

eddie said...

Thanks for your comment!
I will update the post!

Adela said...

Libgen.org is not working too. Sci-hub.org will not work anymore for us since they have restricted some users to reduce traffic because more than half university proxy accounts got closed.

I am considering the idea of quitting academia, with all those spending cuts it will be easier to be a penguin in the middle of Sahara.

eddie said...

Internet is an ocean of opportunities and probably some other service will appear in the future!
And anyway, with or without sci-hub.org, there is still so much knowledge available for free over there!

ahmed_boy said...

hi i'm looking for this paper and i used all the tricks but couldnt find it unless i have to pay. can anybody help me.thx in advance.

ahmed_boy, you can ask for individual papers at http://www.reddit.com/r/scholar - someone will probably hook you up there.

eddie said...

Thanks a lot for your comment!
I have just updated the post with your tip!

Anonymous said...

Well I have tried it in the last few days with a Russian proxy and it is not allowing me to get papers like it used to without the proxy changes. It keeps telling me that I am signed in as:
National Chung Hsing University (Institutional account) and whenI click for paper (on journal access site like ingentaconnect) I'm told page not found. This is very unfortunate as I am in writing PhD mode and my college has useless access to papers and I could've really done with this. Free education my ass!

If anyone could confirm for sure that this is working, I'd appreciate it as then I would know it's not just me.

eddie said...

If the Russian proxy solution doesn't work
try asking directly the author or make a friend working in a University Department in Finland (no joke) :)

Anonymous said...

Eddie, why the Uni Dep. of Finland?

Anonymous said...

I don't know if it is still like this, but until several years ago, as researcher in Finland you had access to a lot a resources (i.e. papers) on the internet.
The education system in Finland was/is great! Really!

Anonymous said...

Sci-hub.org will work with russian proxies, indeed. I've just downloaded a paper from Springer using it. I exceptionally got this one in the first try, but sometimes you'll have to keep trying, which means refreshing your browser or trying again a few minutes later until it works. Right now, for example, i'm trying to get a paper from JSTOR and it won't work - that happens. I've noticed that the most "popular" journals are easier to get since, I suppose, most of the university proxies that sci-hub.org uses have subscriptions to those journals.

eddie said...

Thanks for your clarification. I have just updated the post!

Anonymous said...

Breaking news: sci-hub.org is now working without proxies, which means it is not restricted to russia anymore (at least by now).

What do you mean by "downloading standards"? Could you be more specific?

Hi!, in Chile we have a facebook group:

Here, we exchange the papers using different institution subscription of anyone in the group.
So, you can receive help from an anonymous and you can help to anyone too.

Be carefull when looking for book links using google. Many sites come up that say they have it, then ask for subscription, often paid, then a VIRUS!!

If you are looking for books, install an anti-virus.
AVG Free is good, but not 100%, some enemies are clever. No problem if you mostly visit scholarly sites.

Yeah. Sci hub only shows "File not found.". It need it SO MUCH. I haven't found the article that I need in any other option. I don't know what i'm going to do if Sci-hub ends.

If sci-hub is down... well just wait or try the other methods.
Especially asking the Author/Authors directly, the Finnish option and reddit.
