What does it mean if an item is "restricted" from use in the reading room?

Items that are "Restricted" require permission for access. Usually an item is restricted because it is very fragile or in a special format that requires staff assistance. It may sometimes be restricted because a donor wants to ensure privacy of parts of a collection. 

To request permission to access restricted materials, add a note to your request in the HOLLIS Special Request account. Please indicate the specific reasons that you would like access to the restricted materials. 

Readers who request to see restricted materials will receive a reply to their request as soon as possible.
