KOPERNIO extension to find PDF's : plus Open Access button, Unpaywall, Google Scholar and Connect UPDATED!

I am currently testing 4 browser extensions in Chrome that can help me find the PDF i need.
They seem to be popping up like dandelions in the fields ;-)

(Please read my post on ALL possible options to get to a PDF: )

Here is a first glance of what they do. For testing i used this article:

Kopernio (previously Canary Haz (
Note this is a .com extension. This new company has been founded just 8 months ago. The Kopernio  extension was released just in March 2017. Currently the Kopernio button is in alpha-testing and so far it seems free. The previous name appeared to be a tribute to the #ICANHAZPDF movement (requesting pdf's via Twitter with this hashtag).

Kopernio extends the reach (and functionality) of your library linkresolver to the browser.
It goes beyond the reach of the traditional library linkresolvers which show you if you are entitled to get the full-text based on checking your subscriptions database. It tries to solve the problem of the linkresolvers, early-online issues, publishers holdings- and access registrations. There are always discrepancies, bills not paid, backlog of mutations, titles changes etc etc. 
Kopernio does not only shows users the publications they can immediately open as pdf based on library subscriptions, but also other free versions that are out there on the Web. If your library holdings say NO, but the publisher left it open, you get the pdf. There is no doubt. Either you get it or not.

You HAVE to create an account. If you register with your institutional /corporate email, it is then connected to the proxy settings of that particular library. 
When opening the webpage of a journal article or institutional respositories, e-print-servers etc) a #kopernio bar indicates (just like the Unpaywall tab) immediately IF a pdf has been found.

The first time using Kopernio off-campus, your proxy login details are stored encrypted IN the plugin, and are never shared with Kopernio servers or others.
If your library proxy settings have not yet been added to the Haz-bar give them a shout on Twitter , on Linkedin or Facebook. Their response so far has been excellent. 

They even have added the Groningen institutional repository as the world's first repository activated for Kopernio, on my request! So, every page on that repository, containing a DOI, WILL be "hazzed". I am coining the verb "hazzing" for showing available versions of scientific publications or data (free, open access or licensed) in a browser! ;-) It's is therefore not only using institutional repositories as a source to harvest pdf's, but also as a target to show the Kopernio Get PDF button/bar.

In Search results vs article detailed view (PubMed and Google Scholar)
The Kopernio button appears also in PubMed search results to offer direct access to the pdf, instead on the article view level. This is also activated for Google Scholar search result page, which makes it possible to do pratical comparison between the coverage of Google Scholar itself, Kopernio ánd the Library linkresolver showing up as Library Links in Scholar.


You can then click GET PDF. Your Kopernio registration then allows you to choose to either add it to your LOCKER, Bookmark it to read the article later, or download the pdf.
Clicking on the #kopernio logo in the upper left corner, takes you to the LOCKER with your saved articles/bookmarks. There is a build-in viewer to read your pdfs. You can download the citation to .bib currently.

How does it work?
With thanks to Ben Kaube, one of the founders of Kopernio (previously Canary Haz), I can now write that Kopernio does quite a lot of things in the background, Parallel searches for the best PDF version are made currently:
The following sources are considered:

- Links to PDFs on the page (e.g. as you might find on an OA article page)
- "Deep links" via institutional libraries. This requires authentication against the library the first time Kopernio is used off-campus.
- Kopernio's index of open PDFs articles
- Cached Google scholar results
- Your Kopernio PDF search history known as your "locker"

 They are working with a (fast growing) whitelist of websites right now and they are adding more institutional repositories to these lists too.

Depending on which (if any) of the above returns positive, the bar may take between 1 and 20 seconds to complete its search (Kopernio claims the average is around 3 seconds).
When making a head to head comparison with Unpaywall it's worth considering that the Kopernio link goes straight to the PDF while Unpaywall may take you to a sequence of interstitial pages first.

Kopernio DID find a PDf version which seem to come directly from the publisher, because it is using my library proxy settings! So, I login once, and after that I don't need to do that at all anymore!

Google scholar button
Finds full-text versions on the web. You can connect Google Scholar to your library's linkresolver (OCLC in my case) in Settings; Library Links; find your library and SAVE.
In this case it finds the PDF based on your library subscription AND a free version of I have no idea why this version is available for all, but it does not look to be open access or a final author's version.

Unpaywall ( 
This add-on shows immediately if there is a free version without even having to click. It shows up as a coloured button on the right side in the browser screen.

See a green tab when they find fulltext from an institutional repository or preprint server, and a gold tab when we find journal-hosted content with an Open license. When we find journal-hosted fulltext with no license you'll get a blue tab. And grey means NO full-text available. You can activate the coulour-coded tab in Settings. Another setting can hide content from less trusted sources. You won't see fulltext from ResearchGate,, researcher homepages, and some IRs. This option decreases coverage by about 20%.
Clicking the coloured tab opens up the free version from immediately.

Open Access Button ( 
You have to click the button in the Toolbar to get it working.
In this case -after searching for a few seconds- it does NOT show me any available version, but the Request article or data option. This feature will eventually send a request to the AUTHOR for a copy.

This bookmarklet in your browser forces you to go via the Library proxy-login, wherever you are on the web. It takes you from the PAYwall to the PDF, if the library has access to the full-text based on their subscriptions. You just have to click on the CONNECT in the bookmark-bar. The choice to save your proxy login details in your browser is yours, but it can be very useful.

I am working on a screencast to demonstrate all these extensions. "to be continued' ...

Altmetric at UMCG : Who is talking about your research?

On May 2nd I presented at the Meet&Learn session in the University Medical Center Groningen our Altmetric UMCG project. It was in Dutch. A summary was posted afterwards on the blog For staff of the UMCG: if you want to know more and/or get access to the UMCG Altmetric Dashboard, please contact Guus van den Brekel!

UPDATED: How to get the PDF! Infographic | Find the full-text of e-journals INSIDE OR OUTSIDE the collection of your library ALL OPTIONS

April 20th 2017:
I have added the browser extension Canary Haz ( as a very promising easy tool with many interesting features. Please read more on Canary Haz in my post about browser extensions like UnPaywall, Open Access Button and Google Scholar button.
Currently looking into a Dutch commercial product targetting academic or research libraries also with a browser extension, called @leanlibrary ( )

April 13th 2017:

Updated version! I have added ResearchGate as identified source many researchers use to upload ánd download pdf's (both copyright protected & open access/free versions)

The button says it is searching also in "less trusted sources". ResearchGate,, researcher homepages, and some IRs. You can UNcheck this option in the Unpaywall tool, but they tell us it decreases coverage by about 20%.

Maybe they can adjust the text a little bit regarding the "less trusted sources".. Im am sure many institutional repositories would argue that they ARE a TRUSTED institutional repository!

Does making #openaccess publications available as pdf in institutional repositories have a negative effect on stats of publishers version?

Earlier this week I posted about: "Does making #openaccess publications available as pdf in institutional repositories have a negative effect on stats of publishers version?"
I put the topic on my Facebook 

Some researchers are asking librarians to make full-text pdfs of open access in our repository (Pure) invisible on the research portal, because it would affect the read/download stats on the publishers site in a negative way.

In my opinion open access is about making research and publications as easy findable and accessible as possible, and not about boosting the read/download stats for publications on publisher sites..
What is your opinion? What is your library or institutions policy in making the final publishers versions available  as pdf in your repository?

Here are the comments and responses of Peter Suber (in Italic):

Does making #openaccess publications available as pdf in institutional repositories have a negative effect on stats of publishers version? 

Yes. ​Whenever there are OA copies at one site, they will tend to reduce the downloads of the same works at other sites. 

​BTW, while there's pretty good evidence that OA copies in an institutional repository reduce publisher downloads, there's no evidence that they increase publisher cancellations. And on the other side, there's good evidence that they increase citations to the same works.​

Some researchers are asking librarians to make full-text pdfs of open access in our repository (Pure) invisible on the research portal, because it would affect the read/download stats on the publishers site in a negative way. They are talking about the gold oa articles.

​To me, what's remarkable about this is that authors are identifying with the publisher's interests rathe​r than their own interests. Their interest lies in OA, not in protecting the publisher's stats.

Another dimension of this: If the institutional repository is acting with care, then it's only providing OA when it has legal permission to provide OA. The majority of subscription journals provide this permission through their publishing contracts, and the majority of OA journals provide this permission through their open licenses. Hence, the publishers are *consenting* to this OA. There's no reason for faculty to protect publishers when publishers have the means to protect themselves.
In my opinion open access is about making research and publications as easy findable and accessible as possible, and not about boosting the read/download stats for publications on publisher sites..

Exactly. I completely agree.​
Libraries are adding these pdfs partly to build a local archive, just in case anything might happen to the publishers site ( bankruptcy, take-overs etc...)

I agree that repositories also provide the valuable service of preservation. But if anything, providing open access is even more important.

It almost seems as if researchers think that these publications read/download counts, including other altmetric stats, IS going to effect there bibliographic citations.
One fear that is mentioned out loud is, that it would be bad if the repository version (post-print or final versions) would be quoted in a citation. It would cost them "official" citations.

This is another good reason to de-emphasize metrics based on official citation counts!​ 

Altmetrics would not raise this problem, and evaluating scholars by their quality rather than their citation counts would not raise this problem. 

Peter gave a few links to find more evidence quickly:
​I collect some evidence in the updates and supplements to my book (Open Access, MIT Press, 2012, for pages 152 and 154.

In summary:

Yes, making the pdf of a Open Access article available in an institutional repository, dóes affect the download/read stats on the Publisher's site, bút there is evidence that it increases citations.The permission to make open access available in institutional respositories is legal ánd consented by by Publishers.
The *traffic* is divided between the various locations where open access articles should be offered (personal author site/blog, institutional repository, online Journal....)

No, there is no need to make final publishers versions of open access publications invisible on institutional respositories.
There is a strange fear that other researchers could quote the version available on the institutional respository, but as the actual OA pdf's are downloaded from the Publisher's site, they are always the same for the final publishers versions.
(People might mistake the *green* open access publications in the institutional respository for a citable publication, but when done with care these final author versions are marked and branded very clearly as NOT the final Publishers versions. Many libraries add a special page to the final author version pdf to make this very obvious.)

Yes, also from the preservation aspect, it is a good idea to make the final publishers versions of publications available in the institutional respository.

Plagiarism scan with iThenticate now available via Central Medical Library UMCG

The Graduate School of Medical Sciences (GSMS) now licenses the plagiagism software tool iThenticate with the specific goal to facilitate promotors, and supervisors of doctoral/phd students. 
Doctoral/PHD-students should turn to their promotors and supervisors if they want to scan manuscripts, as only they have access to an account in iThenticate.

All other staff members in the UMCG can -as of now- turn to the Central Medical Library (CMB) of the University Medical Center Groningen (UMCG) to have manuscripts scanned for plagiarism with iThenticate. The CMB will perform the scan in iThenticate, deliver the detailed report and offers to discuss the results with the author. Please send us an email or call us (050) 361 6200) to make an appointment.

Students of the University of Groningen have to turn to their supervisors & teachers in NESTOR to have manuscripts scanned in Ephorus INSIDE Nestor.

For more information on the use of iThenticate in the UMCG, please contact the GSMS.

How to get the PDF? Find the full-text e-journals INSIDE OR OUTSIDE the collection of the library : ALL OPTIONS

Do you want to know ALL OPTIONS to get access to the pdf of an scientific article? You will find all tips and tools below.

The University of Groningen Library has -together with the Central Medical Library UMCG- a very large collection e-journals (e-journals; 50.000+ titels)

The search-engine/catalogue SmartCat, but also the Get it!-button are two main ways to reach the full-text in our collection, but both tools do have their issues. 
Only too often things go wrong in offering our users the direct access to the pdf's. 
(more details on this at the end of the post)
  • We often can not explain this to the customer.
  • This causes frustration and confusion. Many users stop using these tools or disconnect from the library alltogether ...

This is really unnecessary, with the use of the following tips and tools!

    Here is the overview of ALL options to get your PDF!:

    1. Via the Get it!-button, presented in almost all our scientific bibliographic databases, like Pubmed (but also WoS, Scopus etc.)
    Please use always the Pubmed link used  on the CMB-website.

    (Tip: replace your current Favorites link to PubMed with this one: )
    Where ever you are online in the world, you will then always be presented the Get-it!-button on the article-level in Pubmed!

    It is though unfortunately, not a 100% guarantee that you you will get access to the PDF:
      • The best advice we can give you currently is to use the DOI-link (Digital Object Identifyer) presented in each PubMed-record (see the image below) It is shown next to the PUBMED-ID near the bottom of the record. It will take you directly to the publishers/journal-site
        If you can download the PDF there, it is because the library has a subscription (or it's free or Open Access).
        If you can not download the PDF from there, we do not have a current subscription for access to the full-text.

      • Allthough we do have a very large e-journal collection, we do not have everything in subscription!
        The Get it!-button shows if we do or don't have access to the full-text. If we do, you are presented with a link directly to it, but ....
        CURRENTLY THERE IS AN ISSUE WITH THE GET IT!-button in PUBMED. It presents -in some cases- incorrectly the message that we do not have access. we are working very hard to repair/improve this. Please contact us, if you notice something is wrong (
      • Please note that also in the case pre-prints and "early online" versions of articles the Get it!-button might give this incorrect message, due to the fact that it is simply too new, and even the publishers have not integrated the complete metadata themselves. Please try the DOI-link or the Publishers-link in these cases too!

    Other options to get the PDF below!

    2. Using the Eduroam wifi inside the UMCG, will get you access to the PDF without having to use the library proxy-login! 

    If -for some reason- you do NOT get access to the PDF while using Eduroam:
    a. either we do not have a subscription (and it it is not free or Open Access) ÓR
    b.  there is something wrong with the subscription and the online access. This can involve issues with payment, changes, take-over, bankruptcy, errors, mistakes or internet issues.
    On a collection size of 50.000 online journals, there is always a small amount of ongoing issues. 
    Please contact us, if you notice something is wrong (

    3. If you are using links to publishers of journals NOT generated from our library website (CMB-website) and you are NOT using Eduroam in het UMCG:

    a. the Get it!-button will NOT appear ->

    b. Start using our CONNECT-tool for this! This is a button you can easily add to your browser, simular to a favorite-link in your Bookmark- or favourite-bar. This works for a laptop or desktop, but you can also install this on your tablet or smartphone!
    No matter where you are online, this button will take you from the so-called PAYWALL (where they ask you to buy the article for a lot of money), directly to the PDF, with a push of the button (via the library proxy-login)
    Our advice is to: save your login-details of the proxy in your browser!
    Details on how to install the CONNECT-button are here and a short instruction-video.

    c. Extra feature of the CONNECT-button: it makes the Get it!-button appear again in Pubmed for you, if you just started at, instead of using the CMB PubMed-link ;-)

    4. Extra tools and options to get to the PDF
    This button works in Chrome, Firefox, Safari, Internet Explorer and Edge. You have to do a simple email login, to install it.

    b. The Google Scholar-button: simular to the CONNECT-button, but also searches for all possible other available pdf's out there f the same publication
    for CHROME | Firefox (i did not find this for different browsers like IE or Safari)

    c. Use services like DOAI en oaDOI: you can enter the digital object identifier (DOI) and the service will search free-accessible versions of the publications. DOAI and oaDOI search preprint archives, ResearchGate and/or institutional repositories (like our own Pure research database)
    d. NEW! Use the Unpaywall-extension for desktop Chrome
    Get full-text of research papers as you browse, using Unpaywall's index of 10 million legal, open access articles.

    e. For twitter  users: use the hashtag #icanhazpdf together with a link to the requested publication; if somebody has access, they can send you the PDF.

    f. Request a copy at your library; this is not free, but often a fast option, and much cheaper than buying it from the publisher. We have special rates for staff, phd;s and students!
    g. you can of course BUY it from the Publisher or Journal itself anyway...
    h. request a copy from the AUTHOR directly: often not the fastest way, but traditionally a well-used route to get pdf's ...

    i. use our journal app BROWZINE (als web-access )
    By registering as University of Groningen/UMCG staff ánd the use of the library proxy-login, you can get a personalised way of access to all Tables of Content you wish for, ánd direct access to the PDFs of ALL our e-journals. Browzine offers óne interface for all journals, with a lot of extra features that make keeping up to date a lot easier!
     “What you see, is what you get” + “You don’t see, what we don’t have”

    j. Use the journal app READ by QXMD (also as web-access:
    By registering as Universitair Medisch Centrum Groningen staff members, 
    ánd the use of the library proxy-login, you can get a personalised way of access to the latest medical publications, get alerts on new content relevant for you, ánd of course, direct access to the PDFs. Annotations options for pdf is a very neat feature of READ, including the search & topic alert.  
    The CMB now has an institutional license for READ by QXMD. You will be able to SEE our holdings, adn get the PDF even quicker now. (more information soon!)

    k. And last, but not least -to not forget the "elephant in the room"
    - : 
    If all else fails, you have the option to consider using Sci-Hub. It is estimated that it contains currently about 50% of all publications, so you got a pretty good chance to get what you need. There is however a big BUT! There is a RISK in using this "service". In many countries the use of Sci-Hub is considered as an "illegal act", as if involves content protected by copyright laws.
    There are ongoing lawsuites of Elsevier against Sci-Hub.
    As a library, we can not advice the use of Sci-Hub, but research shows the use is worldwide ánd substantial. Use at your own risk.

    Background information on Smartcat and the Get It!-button
    • In SmartCat people get often "lost in multiple presentations of print- and e-content editions. Often the emphasis is on the printed materials, rather than the e-content.
    • The Get it!-button does not always show the correct access information on online full-text access, while the publishers icon in PubMed DOES take the users to the PDF.  Also "ahead-of-print" publications can often not resolveded to the PDF via the Get it!-button. Not only the OCLC linkresolver has this issue, also the others have this issue.
