Presently if a title has a holdings statement attached (holdings 866 I think) or it has a description in an item record, and if the fulfillment rules allow for patron physical requesting, then in addition to item-level request links there will be a "Request other issue" link. The resulting form allows the patron to fill in additional values for chapter, page, volume, issue, part and date. Documentation refers to this as a "Request for a Non-Cataloged Serial Item." However, the link presently appears on non-serial items. Ex: https://librarysearch.williams.edu/permalink/01WIL_INST/1faevhg/alma991013241589702786
Given that this link takes you to a form focused on serials-related metadata, we think this link should only appear on serial titles that meet the other criteria (holdings statement, description, requestable).
Thanks for considering!
