Some of Houghton's material is stored at an offsite storage facility. The HOLLIS catalog lists the location of this material as "Houghton Library Offsite Storage."
You can place a request for offisite material using a HOLLIS Special Request account.
You may have up to six items at a time from offsite storage. Requests for offsite material received by 2:00 PM one business-day in advance arrive around 10:00 AM the following morning. Requests for Mondays must be received by 2:00 PM on the previous Friday, as there are no deliveries over the weekend.
