This session answers the ever elusive question: How do holds work in Evergreen? Take a deep dive into the mechanics of hold fulfillment in Evergreen: targeting and opportunistic capture. We also examine hold configuration options that libraries can use to fine-tune how holds work at their library, including Best Hold Selection Sort Order, Org Unit Proximity Adjustments, and the many Library Settings related to holds. Join us to learn the answers to questions such as: What is the hold-copy map/potentials list? Is the hold queue position a lie? How can my library adjust hold fulfillment order? How can I optimize holds configuration for my library or consortium? And more!
