COMPULOG's Electronic Colloquium on Spatial and Temporal Reasoning (ECSTER) was a precursor to the present Colloquium and Catalogue, and some of the materials presented here have been inherited from ECSTER. In a few cases, the material has not yet been properly integrated, so that the ECSTER structure and the ECSTER headings still remain. This will of course be corrected in due time.
Although these Catalogues already contain a considerable amount of information, there are still some parts of it which are "under construction". We ask for the user's patience.
Much of the bibliographic information presented here is obtained from the LIDOS and ACRES bibliographic resources. In fact, one raison d'Ítre of ACRES is to be used as the basis for colloquiua catalogues such as the present ones.
