invenio offers two different types of search:

1. a general search with one or more search terms – either as a simple search, an advanced search or a name search.
2. a navigating search, which is similar to flicking through a printed catalogue.

Searches are carried out in the descriptive information on the documents (“cataloguing information”, i.e. title, contents note, fonds description). In digitized fonds, it is possible to search for keywords derived from "optical character recognition" (OCR). See advanced search.

A file can only be viewed online if it is available as a digital copy. Files that have not been digitised can be requested for use in the reading room. If you would like to request copies or scans, please contact the responsible department.
