Interlibrary Loans

Microfilm requests will be available to view at the Daniel Boone Branch during the construction of the Clark Family Branch.

Interlibrary Loan allows St. Louis County Library to borrow items from other libraries around the country on behalf of our patrons. This service is available when:

  • The item is not owned by SLCL or SLPL
  • Not available to borrow via MOBIUS or Prospector
  • Must be an Adult Resident or Minor Resident Cardholder, having an account balance no higher than $50.00 and having no more than five items overdue for more than one week

Items that are very new or rare may not be available to borrow. Please allow 6-8 weeks for delivery of all Interlibrary Loan requests


There is a limit of ten requests at a time.

Patrons should wait 90 days to re-request items that the Library has been unable to obtain from other libraries via the interlibrary loan request process.  

Requesting Physical Items

If the desired item is not listed in the catalog and is also not available through MOBIUS and Prospector, sign in to your account or select a SLCL branch from the dropdown, enter your search criteria, and then adjust the 'Select Resources' options to search the OCLC WorldCat database and place your hold on the item if found.

Article Requests: Copy or PDF

Please fill out the ILL Copy Request form in as much detail as possible. Incomplete information may result in a canceled request. Note that requests for copies of entire journals will be denied.
