This means providing counsel to agencies on what information is in demand, how their Web site meets this information demand, and how to set indexing to support citizen discovery. A GILS is not a guarantee of presentation of source documents. In fact, it may only provide a link to a Website for directions on how to obtain the full text. Therefore, it functions best as a matchmaker between agency source and GILS patrons. Indexing every object is vital for hardcopy collections in a library, but may not be needed in the virtual collection of the Internet.
Indexing provides the opportunity to enhance classical cataloging.
In fact, the author or Webmaster's choice of terms may improve discovery. Rewards for indexing collections will accrue over time. Don't expect obvious improvement in searching as the number of 'tagged' documents grows. The value in indexing the virtual collection may not be realized for years. However, it prevents a problem similar to the Y2K issue.
