Organization of electronic resources workflow is critical in the increasingly complicated and complex world of library management. A simple organizational tool that can be readily applied to electronic resources management (ERM) is the use of checklists. Based on the principles discussed in The Checklist Manifesto: How to Get Things Right, the electronic resources staff at University of Maryland University College Library developed checklists for transitioning electronic resources each fiscal year and maintained them in a Springshare LibGuide.

Following the application of checklists, issues reported by library staff and patrons decreased significantly. (Contains 4 figures.)
