Why is the system rejecting my request with the mis-match error message "Lender title or author does not match requested title or author - lender XXXX skipped."?

[Live Shelf Status] With Live Shelf Status activated, the Illume system not only live checks the Lender library Z39.50 server for the status of the item (Available, Checked Out, On Hold etc) but also double-checks that the Lender library actually owns that exact item by checking the ILS for the catalogue record. This is useful when a request is created from a union database record that may be out-dated but can be frustrating when the Lender library's Z39.50 server returns a Title or Author (or other record information) Mis-match error!

The Illume system is set-up to match your request exactly with the Library's catalogue record so you receive the correct item.

TIP: Use the Blank Request Form to submit your request. All Live Shelf Status sites (except BNVI) have currently disabled live shelf checks against requests submitted using the blank request form.

Or check-out the tips below for editing your request to avoid the mis-match error. You can also contact us if you'd like us to over-ride the live shelf check or email the exception sites (BNVI) directly for assistance filling your request.


Rejections occur when a detail (big or small) in the requested Illume master record doesn't exactly match the catalogued record retrieved from the Lender z-target ILS record.

For example when a request is submitted to Surrey Public Libraries (BSUR) for the BC Union Catalogue record "The dark crystal creation myths. (Volume 1)", the details are double-checked against the live BSUR Z39.50 catalogue record available, and the request is rejected because the BSUR catalogue says the title is actually "Dark Crystal Creation Myths Vol 1" NOT "Dark Crystal Creation Myths Volume 1".  It may also reject the request if it finds that the Author mis-matches, for example in the case below the Request said the Author was "Thomas Carter" and the Surrey catalogue record said the Author is "Tom Carter".

Small mis-matches can be common across all Lender Z39.50 targets to differences in cataloguing rules, for example RDA versus LOC.

We agree it's frustrating to have your requests rejected based on such small discrepancies in record details!  We've opened a Helpdesk Ticket with Auto-Graphics about this issue and requested a change to the system to make it more lenient on matching exact details during this shelf status ownership check. In the meantime, there are a couple work-arounds to make your request go through successfully:

  1. When you see this mis-match error message try editing the request details to make it match exactly.  For example on Retry you can edit the Author to say "Carter, Tom" rather than "Carter, Thomas" and the request should successfully go through to BSUR on re-approval. From the error message you can copy and paste the mis-match directly into your request and then Retry!
  2. Submit a Blank Request for the item instead including the changed details, for example a Blank Request for "The dark crystal creation myths. [Vol. 1]" instead of "The dark crystal creation myths. [Volume 1]" should go through to BSUR. Please note this usually only works when submitting it to one specific lender. Note: If desired, Lender Live Shelf Check libraries can also now de-activate shelf status availability checking on requests submitted via Borrower library Blank Request forms.

  3. If you request a lot of items from a particular library, you can add their Z39.50 server as a search target for Staff within Illume. Check the Configuring Search Targets Display guides for more information or contact us directly for assistance. Making a request directly from the Z39.50 search resource record should create a request that matches their ILS catalogue details.
  4. If desired, a library can internally update their ILS catalogue record to reflect these differences.  For example updating the above title from "Vol." to "Volume" in the ILS catalogue record title details should resolve this particular record request issue.

Please contact us if you have any additional suggestions or questions/concerns about this issue. Or if you would like to submit your mis-match request examples to our open Helpdesk ticket. We will let you know about any changes to the matching process or enhancement updates as soon as they become available!
