So, you have an ISBN, ISSN, DOI, or a PMID, but you have no idea what item it corresponds to and whether you can access that item through UMD. Now is the perfect time to use UMD's LibX add-on.
LibX attempts to identify these numerical ids and turn them into links. The links will go directly to our catalog or Database Finder.
Sometimes, LibX might not recognize a numerical ID, or there might already be a cue on the entry. In this case, just select the numerical ID with your mouse and right click to search the ID.
