Specialized Documents. Earlier, we gave some examples of how information providers offer online usage statistics. Some CWISs post such usage statistics online for readers to peruse. In particular, this allows campus information providers to see which documents are the most popular. Some sites merely provide a summary report. Other sites augment reports with a folder offering direct links to the ten most popular titles in the CWIS. Still other sites may offer on‐line graphs showing usage. In most cases, these usage statistics are updated daily or weekly; some WorldWideWeb services report utilization up to the minute. Online usage logs should not include any information that shows specific activity by fully qualified domain name of the client, so as to protect user privacy.
