As a peculiarity of the library’s development, two catalogues are representing the holdings of the institute. The OPAC catalogue includes all titles since the acquisitions year 1995. It offers multiple search possibilities. The journal’s collection (1.600 titles) is completely detectable through the OPAC.
Our holdings with an earlier acquisition year than 1995 have to be searched for in our image catalogue IPAC. This catalogue facilitates a search function for author's name and for keywords. After the input of a search term, the system offers a name or term as a starting point for your search. Continuing from this point it is possible to find the name or term you are looking for by clicking on the numbers at the bottom of the image.
More user instructions for both catalogues and explanations on the transcription system can be found here.
