Sites under construction are excluded unless significant information is available at the time of assessment. However, excluded sites will need to be evaluated at a later date to assess whether they are subsequently suitable for inclusion. Information about electronic journals is automatically included where the journal fits within the subject scope of the gateway, and at least the contents page for the most recent issue of a journal is available for free. In addition, the resource description should include details about the content that is available for free and for a fee via the Internet. Sites purely describing personal experiences or personal opinion are excluded.
Pure advertising is excluded.
However, resources available from a commercial site, such as the catalogue of a publisher or an interactive teaching resource, would be included where a useful service of relevance to the gateway's audience is provided for free. Such examples would be evaluated and described at the individual resource level, indicating in the resource description who has produced the information. Material is excluded if it is strictly local in context. Material that is no longer available is excluded. Resources not accessible from within the UK are excluded.
