As collections of e-books grow, librarians face the challenge of making patrons aware of the titles included in these collections and how to access them. To promote e-book usage, quick response (QR) codes were posted throughout the print book collections at two medical libraries. Once scanned, the QR codes led users to a subject page, listing e-book titles with links for access. The codes were created using URL shorteners, allowing scan data to be recorded. The codes were scanned infrequently at both institutions, however because of minimal cost for creation and maintenance their use is still viewed as beneficial.
