JAIRO: Estimating Japan's Annual Rate of Journal Article Self-Archiving

Japan's JAIRO has harvested 700,000 full-texts self-archived in Japan's 158 Institutional Repositories since 2007. The worldwide baseline average for unmandated self-archiving is 5-25% of the total annual output of the 2.5 million articles per year published in the planet's 25,000 peer-reviewed journals. About 75% of 50,000 articles (i.e., 35,000 full-texts) were deposited in Japan in 2009. On the conservative assumption that research-active universities publish at least 1000 refereed journal articles per year, the estimate would be that those 35K articles represent at most about 22% of those 158 Japanese institutions' annual refereed journal article output. The figure to beat is the unmandated baseline of 5-25%, and the only institutions that consistently beat it are those that mandate self-archiving. Their deposit rates jump to 60% and approach 100% within a few years. There are already 170 self-archiving mandates worldwide registered in ROARMAP -- 96 institutional, 24 departmental and 46 funder mandates -- but alas none yet from Japan. If there are any, it would be very helpful if they would be registered in ROARMAP. Also, although Japan has at least 158 repositories, only 77 of them are registered in ROAR...
