If an Item Is Not Delivered
If you receive a message that an item is not on the shelf, double check the call number and bibliographic information for accuracy and completeness. If the item was an issue of a periodical, consult a reference librarian to find out whether the Library has received the issue and whether it has been bound. If the submitted information was accurate and/or the item was received, you can submit an electronic Special Search Form to the Collections Access, Loan and Management Division (CALM): https://www.loc.gov/rr/cmd/specialsearch_pub_form.html
CALM staff will then conduct a comprehensive, long-term search for the missing item over a 30-day period. Staff can also help gain access to materials that are charged to offices within the Library or are assigned to a reference collection or other location. Reference staff may also be able to identify other area libraries which have copies of an item in their collections.
