How many journals actually allow self-archiving into an Open Access repository?
A. This is a difficult question to give a definitive answer and it is really necessary to review individual publishers using the SHERPA RoMEO database. A related question, then, is “How many publishers are covered by RoMEO?”. Currently the database has records for 386 publishers and it is estimated that this covers between 8,000-9,000 journals; the vast majority of titles of interest to UK researchers. The database is being added to all the time.
