PowerPoint slides for the presentation given June 26, 2011 at the American Librarian Association's Annual Conference in New Orleans, LA. Presentation Description: To tame the complex and ever-changing electronic resource management landscape, electronic resource management systems need to be flexible, evolving and affordable. Two such systems are ERMes and CORAL, developed by libraries for libraries and made freely available. ERMes runs in Microsoft Access and is suitable for small and medium libraries. Released in summer 2010, CORAL, is a modular, web-based system. Presenters will discuss the development, use and future plans for each system.
