In my email this morning, posted to the American Scientist Open Access Forum, was a message about a just-released tool called Journal Info. Designed as a partner website to the Directory of Open Access Journals (DOAJ, at http://www.doaj.org/), Journal Info presents information for about 18,000 journals. Some of the data is basic stuff (e.g. ISSN, publisher URL, etc.) but there is also a nifty section that lists fields dealing with "reader accessibility", most of which are OA-connected. Here's the "reader accessibility" information for the Haworth journal Serials Librarian:
Open Access: No
Allows self-archiving of reviewed manuscript: Yes
Alternative journals with Open Access:Journal of Medical Internet Research
Journal of the Medical Library Association
Information Research: an international electronic journal
more alternative journals ...
There's also a section called "quality" which lists the indexes a journal appears in and something called the Frida Score (Serials Librarian has a "low" Frida score). To be honest, I'm not sure what a Frida Score is; I'll have to do some digging...
Though Journal Info treads into territory held by Ulrich's and others, I think it could be a handy tool, especially the "reader accessibility" section.
The URL for Journal Info is http://jinfo.lub.lu.se/. I was created by the good folks at Lund University Libraries, with financial support from the National Library of Sweden.
