Zusammenfassung:	The size of a document archive is a very important parameter for resource selection in distributed information retrieval systems. In this paper, we present a method for automatically detecting the size (i.e. number of documents) of a document archive, in case the archive itself does not provided such information. In addition, a method for detecting the incremental change of the archive size is also presented, which can be useful for deciding if a resource description has become obsolete and needs to be regenerated. An experimental evaluation of these methods shows that they provide quite accurate information.
