Join us for forty-five minutes guaranteed to be of no interest to non-catalogers as we explain some ideas related to bibs that may not be obvious such as parts, peers, transcendence, and how exactly do volumes fit in the picture? We will also touch on how Evergreen calculates attributes such as search formats, how located URIs work, and how do booking materials fit into things. This presentation is an introduction to the above concepts in cataloging for Evergreen end users.
