Many repositories have a limit on the number of searches they will conduct for each reference letter, and each sets its own fees. Usually, letters are answered within several weeks. Patrons should determine which collections they want to see before coming to an archives. Unfortunately, many patrons drive many miles to do research, only to find out they should have gone elsewhere. Always verify that the repository, especially the smaller facilities, will be open before beginning a research trip, and ask about parking.
Archival materials are unique and irreplaceable, so security is very important to archivists.
If records are lost, stolen, or vandalized, they rarely can be replaced. Archivists have a responsibility to provide access to the materials, but not if the materials can get damaged in the process. Most archivists follow standard security procedures to help ensure that the documentary heritage will be available for everyone. An archives will normally ask patrons to check their bags and fill out a few registration forms. Some archives will provide patrons with paper and pencils.
