The document discusses SERU (Shared Electronic Resource Understanding), a NISO initiative to reduce transaction costs for e-resource licensing by establishing mutual understandings between libraries and publishers instead of requiring formal license agreements. It provides background on the development of SERU, including discussion forums that helped inspire the idea. A working group was formed to draft initial SERU statements addressing topics like subscriptions, appropriate use, and archival access. A pilot period was launched in June 2007 to test SERU, with the goal of formalizing it through NISO in 2008. SERU aims to simplify small transactions while not replacing all license agreements.
