Subject Indexing of Textbooks: Challenges in the Construction of a Discovery System

The purpose of this paper is to present the steps on the way of finding a suitable classification system for subject indexing of textbooks and to integrate this into a resource discovery system. Textbooks are usually not indexed at great length. Yet, the research library of the Georg Eckert Institute has a unique status regarding the range of collected textbooks. This makes a detailed subject indexing indispensable. The currently used local solution shall be replaced by a more standardised solution to serve greater dissemination and compatibility of our data and to simplify the search process for the user.
