What does it mean when Primo indicates a journal "may be available"?
The "may be available" status will sometimes appear next to print journals in Primo depending on the specifics of the metadata in the back-end of the system. In those cases where the system is not able to determine definitively if the volume/issue you are interested in is on the shelf, it will display that status. However, according to the "Summary Holdings" note listed on the journal's record, we should have volumes 18-30 (1989-2001) in the library.
However, we are closed during weekends in the summer, and Monday is Memorial Day. You could certainly stop by on Tuesday, or we could check the stacks for your article that day. Let us know if you would like us to follow up on this citation when the library reopens.
