PASSPORT/PRISM: Search‐to‐produce ratio explained

Abstract

Discusses the change in the search‐to‐produce ratio from 3:1 to 1.5:1 free searches for every produce or update command. Explains what the OCLC considers to be on the ′search′ side and what activities are on the ′produce′ side of the ratio, focusing on numeric and derived keys, title browse, search history, and the use of microenhancers and CD450 searches.
