The ARIADNE Portal consists of a Catalogue providing access to over 3.5 million archaeological resources which can be searched and filtered according to a number of criteria. The returned results from the search facilities provided with the Catalogue are listed individually and also as aggregated results on a map and as a timeline. This Guide aims at helping all end users to get the maximum benefit from using the Catalogue. A separate section of the Portal provides several services to assist archaeologists with their research, from planning data management, exploration and analysis to display of all types of data (including from the ARIADNE Knowledgebase, where applicable). Each of these services has its own information on their use and application, so are not covered by this Guide.
