The Library Annex , also known as the Southeast Ohio Regional Depository, is a high-density library storage facility for the OU Libraries combining filing, retrieval, and delivery services. If you find an item in ALICE that's located in the annex, you can request that the item be delivered to Alden by using the Request Annex or Intercampus button.  See this video on requesting a book from the Annex for a demonstration.
