Scopus has prospectively de-listed (removed) all IDOSI journals from its database. Previously, Scopus had indexed six IDOSI journals. Retrospective indexing data will be retained in the database.
IDOSI means International Digital Organization for Scientific Information. Its URL is http://www.idosi.org, and it claims to be based in Dubai, but it may really be managed from Iran. This publisher has been on my list for a long time — with good reason. IDOSI offers quick and easy acceptance of scholarly articles, a hallmark of low quality and questionable publishers. I strongly recommend against submitting papers to all IDOSI journals. IDOSI publishes 88 gold open-access journals.
Why have the journals been de-listed? I don’t have any solid information on that, but it seems that these and other IDOSI journals have a high number of self-citations. An easy way for a journal to increase its impact factor is to have new articles in the journal cite older articles in the journal. This manipulation can be detected and lead to the de-listing of journals in scholarly indexes and metrics.
The above image shows the list of IDOSI journals formerly indexed by Scopus as it appears on the IDOSI website. Predatory journals often annoyingly refer to their journal titles by their abbreviations; this makes them look like high-impact journals whose titles are abbreviated.
The publisher still includes this box on its website claiming that six of its journals are indexed by Scopus. The de-listing of the six IDOSI journals from Scopus is prospective (from now on). This means that IDOSI articles currently indexed in the database will remain there, but newly published articles will not be added.
The publisher is exploiting the ambiguity of being cut off by Scopus. Yes, the journals are indexed in Scopus, but only the past articles. New articles will not be indexed in Scopus. If you have an article “in process” at IDOSI, it and all other current and future submissions apparently will not be indexed in Scopus.
Also, the World Applied Sciences Journal‘s website still claims to be indexed by Scopus:
In many countries, publishing an article in a Scopus-indexed journal is like publishing an article in an impact-factor journal. The index is used as a measure of quality for tenure, promotion, and annual raises.
Being listed in Scopus and other scholarly databases can mean hundreds of thousands of dollars of extra yearly income for gold (author pays) open-access journals. I think Scopus has been too liberal in its listing of questionable journals in its database and welcome the removal of all IDOSI journals from future indexing.
I think IDOSI is playing games to increase its metrics. I still recommend that all scholars avoid submitting papers to all of the IDOSI journals.
