%X Stack mapping was the last thing on our mind when reference staff requested a small CSS change to Primo locations this summer. However, in the process of clarifying the aims of the request, we not only devised a better way to accomplish them; we also discovered how easy it might be to create our own low-res mapping. We'll show how we employed nothing more than UX analysis, OTB functionality, and existing PDF maps to provide enhanced location names and basic point-of-need maps for virtually every item in our physical inventory. It ain't the Ritz, but feedback indicates it’s good enough for most users. %A Craig Thomas %A Jill Thomas %C Atlanta, GA %L eluna1941 %D 2019 %T DIY Stack Maps in Primo
