To organise this myriad of information and distribute it to the relevant audience every organisation uses a series of core databases. These core databases usually comprise a contact, library and project database. Web technology has provided us with the opportunity to combine such collections with others to reach different audiences. An audience has a key interest in one subject area rather than in the organisation producing the material. The web provides an opportunity to work with other organisations to produce a shared subject site.
Geographical profiles are then possible within such sites.
To reach different audiences an organisation may choose to join different web communities. A community may provide access to different audiences through a variety of sections, from a Kids and schools section to a virtual think tank for researchers and policy makers. The type of material may be handled differently, for example library catalogues are increasingly appearing on the web by combining them through a single search. The results can then be linked to joint information on document delivery a number of libraries can present their catalogues and holdings to a wider audience and begin to organise joint management of collections. More specialist formats have the advantage in being input to cooperative databases that facilities for their digitising and indexing can be shared.
