The depth and breadth by subject is varied – for example under "History & Archaeology" there are currently only two history journals – but there are thirty listed for archaeology. Arts and architecture has pretty good coverage in a variety of languages.

SPARC (the Scholarly Publishing and Academic Resources Coalition) Europe gave this website an award in 2009 "for outstanding achievements in scholarly communication." Must be worth something!
