2. BACKGROUND
»OPEN ACCESS
»Journals and articles on DOAJ
» over 10,000 OA journals
» over 2 million searchable OA articles

3. BACKGROUND
»'PREDATORY' OPEN ACCESS
»Coined by Jeffrey Beall
»"The sort of publishers and journals who aims to collect
article processing fee, but lack rigorous peer review and
proper marking practices"

4. RESEARCH PURPOSE
»Earlier research about 'predatory' OA publishing have so far mainly
concentrated on exposing lacking peer review and scandals involving
publishers and journals.
»There is a lack of serious studies about several aspects of this phenomenon,
including extent and regional effects.
»The aim of this study is to provide a comprehensive understanding of
'predatory' publishers and/or journals in terms of
» the number of journals
» article volumes published over the past five years
» APC costs
» Publication time
» Regional distribution of publishers and authors

5. RESEARCH DESIGN
Sampling process: we take Beall's list of 'predatory' publishers as our
starting point and sample a total of 613 journals

6. MAIN RESULTS
development of article volumes

7. MAIN RESULTS
average number of articles per journal

8. MAIN RESULTS
average article processing fee
The average APC over journals is estimated
to be 304 USD, but calculated for articles
turns out to be only 178 USD.

9. MAIN RESULTS
country of publishers
»38.7% -Asia
»26.8% -Impossible to
determine
» 17.5% - North America

10. MAIN RESULTS
country of authors
»60.3% - Asia
» 34.7% - India
»16.4% - Africa

11. CONCLUSIONS
» Over the past five years, there was a dramatic rise in the
number of article published by 'predatory' journals with
exceptional low APCs of 178 USD per article and a
short publishing time between 2-3 months.
» The problem of ‘predator’ is highly limited and regional
to a few developing countries, where ‘international
publication’ is a prerequisite for academic appointment,
more funding, or promotion.
