Many of these views are based on the format of the information resource (for example, “Pictures and Photos”). Others reflect a topic approach (for example “About People and Organisations”). The number of collection views, and the boundaries between them, may change as the scope of the service develops, and in response to feedback from users. In the future, there may be additional views reflecting disciplines (such as “Music”) which are represented in multiple resource formats, or views reflecting a wider contextual perspective (such as “Research”).
