National statistics are collected and reported by libraries for a variety of reasons. The presenter was recently asked to report statistics about her library's collections for ARL, AAHSL, ABET, CEAL and IPEDS, each of whom ask a variety of questions about disparate data points. Her institution recently migrated from Voyager to Alma, and she found that the data is not comparable between the prior and subsequent years to this migration. The differing statistical collection methods between Voyager and Alma / Analytics will be discussed, and if time allows, the presenter would appreciate any tips for collecting collection-based data and its use in your institutional assessments!
