A longitudinal comparison of citation rates and growth among open access
journals

David J Solomon, Mikael Laakso,Bo-Christer Björk

Abstract

The study documents the growth in the number of journals and articles along
with the increase in normalized citation rates of open access (OA) journals
listed in the Scopus bibliographic database between 1999 and 2010.
Longitudinal statistics on growth in journals/articles and citation rates
are broken down by funding model, discipline, and whether the journal was
launched or had converted to OA. The data were retrieved from the web sites
of SCIMago Journal and Country Rank (journal /article counts),
 JournalM3trics (SNIP2 values), Scopus (journal discipline) and Directory
of Open Access Journals (DOAJ) (OA and funding status). OA
journals/articles have grown much faster than subscription journals but
still make up less that 12% of the journals in Scopus. Two-year citation
averages for journals funded by article processing charges (APCs) have
reached the same level as subscription journals. Citation averages of OA
journals funded by other means continue to lag well behind OA journals
funded by APCs and subscription journals. We hypothesize this is less an
issue of quality than due to the fact that such journals are commonly
published in languages other than English and tend to be located outside
the four major publishing countries.
