Catalogue information

Catalogue information

All books and journals, CD-ROMs, microforms, the dissertation collections and the collection of Medieval manuscripts on microfilm are listed in our webOPAC online catalogue.

Only those titles acquired since around 1990 are indexed by keywords. Books included in legacy archives are generally not indexed by keyword.

Since 2004 the tables of contents of all newly acquired collected volumes have been scanned and can be searched in the webOPAC catalogue via the "Table of contents" search option. Further details are available here.

Medieval manuscripts on microfilm can be searched via the “Title” search option. It is necessary to supply a title by specifying the library to which they belong and that library’s shelfmark, for example "[Filmed manuscript:] München, Bayerische Staatsbibliothek, Clm 24164". For part of the manuscript collection (approx. 400), the catalogue also includes a description of their contents that can be searched via the "Manuscript contents" option. Further details are available here.

Lists of new acquisitions in the preceding six weeks can be accessed via the webOPAC homepage.
