[GOAL] Re: Tech tip for journals contributing metadata to DOAJ; check your publication years in DOAJ

[Dietrich Rordorf / MDPI]

Dear Heather,

I think the count on DOAJ is pretty correct if the Publisher delivers
metadata correctly. It can always happen that a Publishers re-submits
the one or the other paper if the first submission was erroneous. I
found in the past that it is not so easy to delete an entry from DOAJ (I
had to ask the staff members). So actually the article count on DOAJ,
including those resubmissions, is usually lsightly higher than on the
Publisher website.

Examples:

International Journal of Molecular Sciences (DOAJ versus --> Publisher
website)
2014 (1469)   --> 1435, see: 
http://mdpi.com/search?journal=ijms&year_from=2014&year_to=2014 etc.
2013 (1373)   --> 1367
2012 (1124)   --> 1082
2011 (632)   --> 631
2010 (339)   --> 339
etc.

International Journal of Environmental Research and Public Health (DOAJ
versus --> Publisher website)
2014 (786)   --> 779, see: 
http://mdpi.com/search?journal=ijerph&year_from=2014&year_to=2014 etc.
2013 (454)   --> 454
2012 (307)   --> 306
2011 (277)   --> 277
2010 (268)   --> 267
etc.

About the "World Journal of Gastroenterology" mentioned in your blog
post, I have yet another article count based on CrossRef doi deposits.
You can access its article number stats based on CrossRef doi deposits
here (the CrossRef-based count is quite different from the DOAJ count,
yet seems closer to DOAJ than the number you report based on the
Publisher website): http://sciforum.net/statistics/journal/articles/13016

Journal: World Journal of Gastroenterology
Partly open access
Current Publisher: Baishideng Publishing Group Co  (doi prefix:
10.3748),  2004-2015
Year: :2004-2015
ISSN / EISSN: 10079327 / -
Total articles: ≅8'184
Indexing: SCOPUS - (1998-) PUBMED - (2001-) MEDLINE - (2001-) MEDICUS -
(2001-) PMC SCIE EBSCO
Archiving: SHERPA/ROMEO (gray)

Please also note that one of the major open access publishers, namely
PLoS, does not deliver article-level metadata to DOAJ since quite a
while. PLoS published around 36K and 35K articles in 2013 and 2014
respectively. Probably the view here is more realistic (yet, it does
only count OA papers that have a doi number registered and deposited to
CrossRef):

Best regards,
Dietrich
