Abstract
The interfaculty centre of Bologna University began 2 years ago a project to 'translate' UDC codes into a user friendly thesaurus, with the object of creating an accurate, easy to use tool for online researches, especially those relating to periodical titles. The UDC numerical codes have been linked by a method based on synonyms to a series of corresponding verbal indices which express in natural language the concepts expressed by the codes. Thus researchers can retrieve information not only through UDC codes but also through their analogous verbal descriptors. Describes the progress of the UDC project so far, and some problems encountered
