When a user browses the Drug Industry Document Archive (DIDA), executes searches, or downloads documents, certain information about the visit is gathered and stored automatically.

• the Internet domain and IP address from which the DIDA was accessed,


• the type of browser and operating system used to access the DIDA,


• the date and time the DIDA was accessed,


• the pages visited, and


• the address of the last site visited before linking to the DIDA.

This automatically gathered information is analyzed to make the site more useful to visitors and to assess system performance or identify problems. We also aggregate such data to report, for example, how many visitors use the site on a monthly or yearly basis. The Library does not track the searches or document requests of individual users.
