Hi, I'm looking for a way to send a Call Number to WebOPAC via a query so that I can return data (title, author, etc…) for a specific book in the catalog preferably in JSON or XML (I'll even take text at this point). I'm thinking that one way to accomplish this is via Z39.50 and send a query to the backend that powers WebOPAC Has anyone done something similar to this? PHP YAZ (https://www.indexdata.com/phpyaz) looks promising, but I'd appreciate any guidance. Thanks, Juan Madrigal Web Developer Web and Emerging Technologies University of Miami Richter Library
