ABSTRACT
The focus for this chapter is the information manager facing choices on how to organise her or his collection(s) for access by end users. The ‘collection’ may be real or virtual, composed of books; paragraphs or sections in a book; articles, patents, videos, images, records in a database, an incoming news feed, sites or pages on a network. Despite the variety, we shall consider all the items as ‘documents’, rather broadly defined. Some virtual collections may seek to integrate internal with external resources. Sometimes they will be used to ‘push’ unsolicited items to users; at other times they will serve as resources for answering queries.
