The people at the journal Pecia: Ressources en médiévistique have issued a call for papers for vol. 15 (2006) of the journal. The journal is devoted essentially to book production and manuscripts in the middle ages, although you’ll see issues of the journal devoted to any number of specialized topics (e.g., relics and sanctity in the middle ages). Articles are in all the main languages (French, English, Italian; I haven’t yet come accross any in German or Spanish).

You can find a table of contents for published issues, and a provisory one for future issues, at their web site, which also has many valuable links to other sites dealing with medieval studies.
