Open Access Growth Surprises with Numbers

Consider these facts:

Open access has proven to be a powerful force that shows no signs of slowing down in 2013.

PMC, the National Institutes of Health archive of freely available full-text journal articles, began in 2000 with two journals and 2,345 articles, and by 2012 grew to include 3,374 contributing journals and over 2.6 million articles, an increase in articles of 110,874 percent.

The Directory of Open Access Journals (DOAJ), a quality-controlled listing of open access scholarly journals, originated with 34 journals in 2002. It now lists 8,527, with 4,250 searchable at the article-level.

Open access articles and other materials are not well-indexed in commercial databases, making repositories a valuable addition to search strategies. Global directories of repositories have grown rapidly in response, and serve as powerful search engines, and include:

Quality control of open access journals is a concern shared by many. The 2013 Beall’s List of Predatory, Open-Access Publishers entries increased from 24 to 260 (1,083 percent) over 2012, with a 19.2 percent (50/260) overlap with DOAJ, which may reflect a difference in inclusion criteria.

The increased number of options for OA publishing brings a caveat: it remains the duty of authors to judge the quality of each journal on its own merits as new publications appear and mature, and experimentation in open access business models continues.
