[This post is part of an ongoing series about impact factors]

In the world of abused performance metrics, the impact factor is the undisputed heavyweight champion of the (publishing) world.

It has been an eventful year in the boxing ring of scientific publishing since the last set of figures were published by Thomson-Reuters. A brand new journal called PeerJ launched with a radical publish ’til you perish business model [1]. There’s another new journal on the way too in the shape of eLifeSciences – with it’s own significant differences from current publishing models. Then there was the Finch report on Open Access. If that wasn’t enough fun, there’s been the Alternative metrics “Altmetrics” movement gathering pace [2], alongside suggestions that the impact factor may be losing its grip on the supposed “title” [3].

The impact factors below are the most recent, published June 28th 2012, covering data from 2011. Love them or loathe them, use them or abuse them, game them or shame them … here is a tiny selection of impact factors for the 10,675 journals that are tracked in Journal Citation Reports (JCR) ordered by increasing punch power.

WARNING: Abusing these figures can seriously damage your Science – you have been warned! Normal caveats apply, see nature.com/metrics.

Web analytics: Numbers speak louder than words

Two hundo! by B. Rosen

According to the software which runs this site, this is the 200th post here at O’Really To mark the occasion, here are some stats via WordPress with thoughts and general navel-gazing analysis paralysis [1] on web analytics. It all started just over six years ago at nodalpoint with help from Greg Tyrelle, the last four years have been WordPressed with help from Matt Mullenweg. WordPress stats are unfortunately very primitive compared to the likes of Google Analytics and don’t give you access to the server log files either. WordPress probably flatters to deceive by exaggerating page views and encouraging users to post more content, but it doesn’t count self-visits to the blog. Despite all the usual limitations of the murky underworld of web analytics and SEO, here are the stats, warts and all.

As of May 2012, this blog is just shy of 200,000 page views in total with 500+ comments (genuine) comments and 100,000+ spam comments nuked by the Akismet filter. The busiest day so far was the 15th February 2012 with 931 views of a post in a single day which got linked to by the Wall Street Journal. The regular traffic is pretty steady around the 1,000 views per week (~4000 views per month) mark. Most readers come from the United States, United Kingdom and Germany (jawohl! in that order) which breaks down as follows:

Dear Thomson Reuters, you should have an associates scheme like Amazon. I’m advertising your commercial product (Journal Citation Reports) for free! I’m far too kind, please send me a generous cheque immediately for my troubles or I will remove all links to your product.

Lots of people looking for the lyrics of the Friends sitcom jingle don’t know what “Your love life’s D.O.A.” means. Glad to be of service.


Traffic here is fairly modest compared to some blogs, but is still significant and to my mind justifies the time spent blogging. It is great fun to blog, and like most things in life, it can be very time consuming to do well. There is a long way to go before reaching the 10,000 hours milestone, maybe one day.

What people are actually interested in reading, and what you think they will be interested in reading are often two completely different things. Solo blogging has disadvantages and it’s been very tempting to try and join one of the many excellent blogging collectives like PLoS Blogs, Occam’s Typewriter or the Guardian science blogs. For the meantime though, going it alone on a personal domain name has it’s advantages too.

So, if you’ve read, commented or linked to this site, thank you very much. I hope you enjoy reading these posts as much as I enjoy writing them. Like smartphones and wifi, it’s hard to imagine life without blogs and bloggers.

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.

Impact Factor Boxing 2010

Golden Gloves Prelim Bouts by Kate Gardiner[This post is part of an ongoing series about impact factors. See this post for the latest impact factors published in 2012.]

Roll up, roll up, ladies and gentlemen, Impact Factor Boxing is here again. As with last year (2009), the metrics used in this combat sport are already a year out of date. But this doesn’t stop many people from writing about impact factors and it’s been an interesting year [1] for the metrics used by many to judge the relative value of scientific work. The Public Library of Science (PLoS) launched their article level metrics within the last year following the example of BioMedCentral’s “most viewed” articles feature. Next to these new style metrics, the traditional impact factors live on, despite their limitations. Critics like Harold Varmus have recently pointed out that (quote):

“The impact factor is a completely flawed metric and it’s a source of a lot of unhappiness in the scientific community. Evaluating someone’s scientific productivity by looking at the number of papers they published in journals with impact factors over a certain level is poisonous to the system. A couple of folks are acting as gatekeepers to the distribution of information, and this is a very bad system. It really slows progress by keeping ideas and experiments out of the public domain until reviewers have been satisfied and authors are allowed to get their paper into the journal that they feel will advance their career.”

To be fair though, it’s not the metric that is flawed, more the way it is used (and abused) – a subject covered in much detail in a special issue of Nature at http://nature.com/metrics [2,3,4,5]. It’s much harder than it should be to get hold of these metrics, so I’ve reproduced some data below (fair use? I don’t know I am not a lawyer…) to minimise the considerable frustrations of using Journal Citation Reports (JCR).

Love them, loathe them, use them, abuse them, ignore them or obsess over them … here’s a small selection of the 7347 journals that are tracked in JCR  ordered by increasing impact.

Popular, personal and public data: Article-level metrics at PLoS

PLoS: The Public Library of ScienceThe Public Library of Science (PLoS) is a non-profit organisation committed to making the world’s scientific and medical literature freely accessible to everyone via open access publishing. As recently announced they have just published the first article-level metrics (e.g. web server logs and related information) for all articles in their library. This is novel, interesting and potentially useful data, not currently made publicly available by other publishers. Here is a  selection of some of the data, taken from the full dataset here (large file), which includes the “top ten” papers by viewing statistics.

*The rank is based on the 12,549 papers for which viewing data (combined usage of HTML + PDF + XML) are available.

**Citation counts are via PubMedCentral (data from CrossRef and Scopus is also provided, see Bora’s comments and commentary at Blue Lab Coats.)

Science is not a popularity contest but…

Analysing this data is not straightforward. Some highly-viewed articles are never cited (reviews, editorial, essays, opinion, etc). Likewise, popularity and importance are not the same thing. Some articles get lots of citations but few views, which suggests that people are not actually reading the papers them before citing them. As described on the PLoS website article-level-metrics.plos.org:

“When looking at Article-Level Metrics for the first time bear the following points in mind:

  • Online usage is dependent on the article type, the age of the article, and the subject area(s) it is in. Therefore you should be aware of these effects when considering the performance of any given article.
  • Older articles normally have higher usage than younger ones simply because the usage has had longer to accumulate. Articles typically have a peak in their usage in the first 3 months and usage then levels off after that.
  • Spikes of usage can be caused by media coverage, usage by large numbers of people, out of control download scripts or any number of other reasons. Without a detailed look at the raw usage logs it is often impossible to tell what the reason is and so we encourage you to regard usage data as indicative of trends, rather than as an absolute measure for any given article.
  • We currently have missing usage data for some of our articles, but we are working to fill the gaps. Primarily this affects those articles published before June 17th, 2005.
  • Newly published articles do not accumulate usage data instantaneously but require a day or two before data are shown.
  • Article citations as recorded by the Scopus database are sometimes undercounted because there are two records in the database for the same article. We’re working with Scopus to correct this issue.
  • All metrics will accrue over time (and some, such as citations, will take several years to accrue). Therefore, recent articles may not show many metrics (other than online usage, which accrues from day one). ”

So all the usual caveats apply when using this bibliometric data. Despite the limitations, it is more revealing than the useful (but simplistic) “highly accesssed” papers at BioMedCentral, which doesn’t always give full information on what “highly” actually means next to each published article. It will be interesting to see if other publishers now follow the lead of PLoS and BioMed Central and also publish their usage data combined with other bibliometric indicators such as blog coverage. For authors publishing with PLoS, this data has an added personal dimension too, it is handy to see how many views your paper has.

As paying customers of the services that commercial publishers provide, should scientists and their funders be demanding more of this kind of information in the future? I reckon they should. You have to wonder, why these kind of innovations have taken so long to happen, but they are a welcome addition.

Open Access Day: Why It Matters

Open Access Day 14th October 2008Today, Tuesday the 14th of October 2008, is Open Access Day. Like many others, this blog post is joining in by describing why Open Access matters – from a personal point of view. According to the wikipedia article Open Access (OA) is “free, immediate, permanent, full-text, online access, for any user, web-wide, to digital scientific and scholarly material, primarily research articles published in peer-reviewed journals. OA means that any individual user, anywhere, who has access to the Internet, may link, read, download, store, print-off, use, and data-mine the digital content of that article. An OA article usually has limited copyright and licensing restrictions.” What does all this mean and why does it matter? Well, in four question-and-answer points, here goes… (more…)
