News that Reed Elsevier is in talks to buy Mendeley.com will have many scientists reaching for their “delete account” button. Mendeley has built an impressive user-base of scientists and other academics since they started, but the possibility of an Elsevier takeover has worried some of its users. Elsevier has a strained relationship with some groups in the scientific community [1,2], so it will be interesting to see how this plays out.

If you’ve built a personal library of scientific papers in Mendeley, you won’t just want to delete all the data, you’ll need to export your library first, delete your account and then import it into a different tool.

Disclaimer: I’m not advocating that you delete your mendeley account (aka #mendelete), just that if you do decide to, here’s how to do it, and some alternatives to consider. Update April 2013, it wasn’t just a rumour.

Exporting your Mendeley library

Open up Mendeley Desktop, on the File menu select Export. You have a choice of three export formats:

  1. BibTeX (*.bib)
  2. RIS – Research Information Systems (*.ris)
  3. EndNote XML (*.xml)

It is probably best to create a backup in all three formats just in case as this will give you more options for importing into whatever you replace Mendeley with. Another possibility is to use the Mendeley API to export your data which will give you more control over how and what you export, or trawl through the Mendeley forums for alternatives. [update: see also comments below from William Gunn on exporting via your local SQLite cache]

Deleting your Mendeley account #mendelete

Login to Mendeley.com, click on the My Account button (top right), Select Account details from the drop down menu and scroll down to the bottom of the page and click on the link delete your account. You’ll be see a message We’re sorry you want to go, but if you must… which you can either cancel or select Delete my account and all my data. [update] To completely delete your account you’ll need to send an email to privacy at mendeley dot com. (Thanks P.Chris for pointing this out in the comments below)

Alternatives to Mendeley

Once you have exported your data, you’ll need an alternative to import your data into. Fortunately, there are quite a few to choose from [3], some of which are shown in the list below. This is not a comprehensive list, so please add suggestions below in the comments if I missed any obvious ones. Wikipedia has an extensive article which compares all the different reference management software which is quite handy (if slightly bewildering). Otherwise you might consider trying the following software:

One last alternative, if you are fed up with trying to manage all those clunky pdf files, you could just switch to Google Scholar which is getting better all the time. If you decide that Mendeley isn’t your cup of tea, now might be a good time to investigate some alternatives, there are plenty of good candidates to choose from. But beware, you may run from the arms of one large publisher (Elsevier) into the arms of another (Springer or Macmillan which own Papers and ReadCube respectively).

The Open Access Irony Awards: Naming and shaming them

Ask me about open access by mollyaliOpen Access (OA) publishing aims to make the results of scientific research available to the widest possible audience. Scientific papers that are published in Open Access journals are freely available for crucial data mining and for anyone or anything to read, wherever they may be.

In the last ten years, the Open Access movement has made huge progress in allowing:

“any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers.”

But there is still a long way to go yet, as much of the world’s scientific knowledge remains locked up behind publisher’s paywalls, unavailable for re-use by text-mining software and inaccessible to the public, who often funded the research through taxation.

Openly ironic?

ironicIronically, some of the papers that are inaccessible discuss or even champion the very Open Access movement itself. Sometimes the lack of access is deliberate, other times accidental – but the consequences are serious. Whether deliberate or accidental, restricted access to public scientific knowledge is slowing scientific progress [1]. Sometimes the best way to make a serious point is to have a laugh and joke about it. This is what the Open Access Irony Awards do, by gathering all the offenders in one place, we can laugh and make a serious point at the same time by naming and shaming the papers in question.

To get the ball rolling, here is are some examples:

  • The Lancet owned by Evilseviersorry I mean Elsevier, recently  published a paper on “the case for open data” [2] (please login to access article). Login?! Not very open…
  • Serial offender and über-journal Science has an article by Elias Zerhouni on the NIH public access policy [3] (Subscribe/Join AAAS to View Full Text), another on “making data maximally available” [4] (Subscribe/Join AAAS to View Full Text) and another on a high profile advocate of open science [5] (Buy Access to This Article to View Full Text) Irony of ironies.
  • From Nature Publishing Group comes a fascinating paper about harnessing the wisdom of the crowds to predict protein structures [6]. Not only have members of the tax-paying public funded this work, they actually did some of the work too! But unfortunately they have to pay to see the paper describing their results. Ironic? Also, another published in Nature Medicine proclaims the “delay in sharing research data is costing lives” [1] (instant access only $32!)
  • From the British Medical Journal (BMJ) comes the worrying news of dodgy American laws that will lock up valuable scientific data behind paywalls [7] (please subscribe or pay below). Ironic? *
  • The “green” road to Open Access publishing involves authors uploading their manuscript to self-archive the data in some kind of  public repository. But there are many social, political and technical barriers to this, and they have been well documented [8]. You could find out about them in this paper [8], but it appears that the author hasn’t self-archived the paper or taken the “gold” road and pulished in an Open Access journal. Ironic?
  • Last, but not least, it would be interesting to know what commercial publishers make of all this text-mining magic in Science [9], but we would have to pay $24 to find out. Ironic?

These are just a small selection from amongst many. If you would like to nominate a paper for an Open Access Irony Award, simply post it to the group on Citeulike or group on Mendeley. Please feel free to start your own group elsewhere if you’re not on Citeulike or Mendeley. The name of this award probably originated from an idea Jonathan Eisen, picked up by Joe Dunckley and Matthew Cockerill at BioMed Central (see tweet below). So thanks to them for the inspiration.

For added ironic amusement, take a screenshot of the offending article and post it to the Flickr group. Sometimes the shame is too much, and articles are retrospectively made open access so a screenshot will preserve the irony.

Join us in poking fun at the crazy business of academic publishing, while making a serious point about the lack of Open Access to scientific data.

* Please note, some research articles in BMJ are available by Open Access, but news articles like [7] are not. Thanks to Trish Groves at BMJ for bringing this to my attention after this blog post was published. Also, some “articles” here are in a grey area for open access, particularly “journalistic” stuff like news, editorials and correspondence, as pointed out by Becky Furlong. See tweets below…

How many unique papers are there in Mendeley?

Lex Macho Inc. by Dan DeChiaro on Flickr, How many people in this picture?Mendeley is a handy piece of desktop and web software for managing and sharing research papers [1]. This popular tool has been getting a lot of attention lately, and with some impressive statistics it’s not difficult to see why. At the time of writing Mendeley claims to have over 36 million papers, added by just under half a million users working at more than 10,000 research institutions around the world. That’s impressive considering the startup company behind it have only been going for a few years. The major established commercial players in the field of bibliographic databases (WoK and Scopus) currently have around 40 million documents, so if Mendeley continues to grow at this rate, they’ll be more popular than Jesus (and Elsevier and Thomson) before you can say “bibliography”. But to get a real handle on how big Mendeley is we need to know how many of those 36 million documents are unique because if there are lots of duplicated documents then it will affect the overall head count.

Michael Ley on Digital Bibliographies

Michael Ley

Michael Ley is visiting Manchester this week, he will be doing a seminar on Wednesday 3rd June, here are some details for anyone who is interested in attending:

Date: 3rd Jun 2009

Title: DBLP: How the data get in

Speaker: Dr Michael Ley. University of Trier, Germany

Time & Location: 14:15, Lecture Theatre 1.4, Kilburn Building

Abstract: The DBLP (Digital Bibliography & Library Project) Computer Science Bibliography now includes more than 1.2 million bibliographic records. For Computer Science researchers the DBLP web site now is a popular tool to trace the work of colleagues and to retrieve bibliographic details when composing the lists of references for new papers. Ranking and profiling of persons, institutions, journals, or conferences is another usage of DBLP. Many scientists are aware of this and want their publications being listed as complete as possible.

The talk focuses on the data acquisition workflow for DBLP. To get ‘clean’ basic bibliographic information for scientific publications remains a chaotic puzzle.

Large publishers are either not interested to cooperate with open services like DBLP, or their policy is very inconsistent. In most cases they are not able or not willing to deliver basic data required for DBLP in a direct way, but they encourage us to crawl their Web sites. This indirection has two main problems:

  1. The organisation and appearance of Web sites changes from time to time, this forces a reimplementation of information extraction scripts. [1]
  2. In many cases manual steps are necessary to get ‘complete’ bibliographic information.

For many small information sources it is not worthwhile to develop information extraction scripts. Data acquisition is done manually. There is an amazing variety of small but interesting journals, conferences and workshops in Computer Science which are not under the umbrella of ACM, IEEE, Springer, Elsevier etc. How they get it often is decided very pragmatically.

The goal of the talk and my visit to Manchester is to start a discussion process: The EasyChair conference management system developed by Andrei Voronkov and DBLP are parts of scientific publication workflow. They should be connected for mutual benefit?

Semantic Biomedical Mashups with Connotea

Mashup or Shutup

The Journal of Biomedical Informatics (JBI), will soon be publishing their special issue on Semantic Biomedical Mashups (can you fit any more buzzwords into a Call For Papers?!). Ben Good and friends have submitted a paper on their Entity Describer which extends connotea using some Semantic Web goodness. They’d appreciate your comments on their submitted manuscript over at i9606. As Ben says, their pre-publication turns out to be an interesting experiment “figuring out how blogging might fit into the academic publishing landscape”. If this interests you, get commenting now!

Update: Just spotted this interesting graphic of the Elsevier / Evilsevier logo (snigger), who are the publishers of JBI…
