A handy new combo list of the open ejournal titles included in PubMed, Scopus and the ISI Master Journal List…
Languages and Literatures: 280
History and Archaeology: 198
Philosophy and Religion: 162
Communication and Information: 145
Arts and Architecture: 137
General and Multidisciplinary: 43
Total of the above, at Dec 2012: 965.

“The Web of Science database (including Arts & Humanities Citation Index, Science Citation Index, and Social Sciences Citation Index) now indexes close to 1,000 peer-reviewed open access titles”.
But I just found a paper published in 2012, “Challenges for open access journals”, which gave a figure of… “864 open access journals” in arts and humanities in Web of Science.
