Combining punctual statistical data compilation, access to real-time order and payment information, and harmonious workflow and reporting tools in one place has long been the Holy Grail for libraries seeking a reliable means for tracking costly electronic resources. This is the tale of two academic libraries that have adopted very different types of electronic resource management systems (ERMS) to attain these goals. This proceeding will provide complementary case studies of the implementation process at Binghamton University where two commercial ERM systems are used, and at The University of Texas at Tyler where an open source ERM is utilized.
