#OA Is PLoS ONE now the largest journal by number of articles? Currently 6385 papers indexed in PubMed for 2010 (and 4400 for 2009). - http://www.ncbi.nlm.nih.gov/pubmed...]
According to http://poeticeconomics.blogspot.com/2009... , the largest ones in 2008 were PHYS REV B (5782) and APPL PHYS LETT (5449). Anyone have their figures (or those of other contenders, or more accurate ones for PLoS ONE) for 2009 and 2010? - Daniel Mietchen from Bookmarklet
Also interesting to see that of those 6385, only 6365 are currently in PMC, so a batch of about one day seems not to have made it there yet. - Daniel Mietchen
Final number for 2010 for PLoS ONE seems to be (around?) 6800, as per http://blogs.plos.org/everyon... . - Daniel Mietchen
Actually, we published 6,749 articles in 2010 (use our Advanced Search, which is worth trying for all sorts of interesting queries). Given the data in the Poetic Economics blog post, I would say that does make PLoS ONE the largest journal in the world (by # of papers). See: http://www.plosone.org/search... - Peter Binfield
Thanks, Peter - hadn't thought of using the Advanced Search for this yet. Do you have any idea why the numbers differ between that and the PubMed search (e.g. 4405 vs 4400 in 2009)? - Daniel Mietchen
Well, its very close. Perhaps the final few papers from 2009 got registered by them in 2010? Perhaps retractions get 'removed' from their count? They are on the East coast and we are PST, so perhaps their definitions of timezones are causing the difference? We sometimes have problems with papers that we want to fix before posting to PMC (at which point they get propagated to multiple locations so it is better to 'fix' it before the propagation). Or some combination? - Peter Binfield
Thank you, Peter - all of these seem possible from my end. As for retractions, Advanced Search didn't bring up anything better than http://www.ncbi.nlm.nih.gov/pubmed...] or http://www.google.de/search...". Could be good to have w.r.t. http://ff.im/vDyWt , though - http://pmretract.heroku.com/journal... only gives the top retractors. - Daniel Mietchen
It looks to me like PLoS ONE is now the world's largest journal, I have updated my 2009 post at http://poeticeconomics.blogspot.com/2011... Comments welcome. - Heather Morrison
Whether the largest yet or not, what must be beyond doubt is that PLoS ONE is the fastest growing journal of all time. - Chris Surridge
Indeed Chris, and as the original Managing Editor you deserve a lot of credit there! Interestingly, it is now more than clear that other publishers are taking notice and rapidly launching titles with very similar editorial policies to PLoS ONE, and all featuring Article Level Metrics (examples include Nature's Scientific Reports, SAGE Open, AIP Advances etc) - Peter Binfield
Dear Heather, I just checked Journal Citation Reports, 2009 edition. Back then the top 3 were Phys Rev B, Appl Phys Lett and J Appl Phys, very closely followed by PLOS One. The average length of a PRB article is 7-8 pp., the typical PLOSOne article is approx. 10 pp. long (Peter Binfield may be able to verify this). Thus it is likely that PLOS One would also be the largest journal measured by shelf size if we had to archive a print copy (about 3,7 m, if you would bind it; one volume each week at a spine width of 7 cm). Phys Rev B would now consume 2,6 m / year but we cancelled print way back in 2001/02. This is primary journals, of course. The largest printed Abstracts journal, Chemical Abstracts, ceased publication recently after volume 151.2009. The latest output was roughly 140,000 pages of abstracts plus 220,000 pages in the 2 volume indexes, occupying together over 4+7 m shelf space... - Bernd-Chr. Kämper
Just clocked that this number of papers for is 18-19 per day. Astonishing. - Matthew Todd
Mat, I hadn't done that calculation either -- that really brings it home. I'm in awe. - Bill Hooker
