OCLC WorldCat Quality Report

My job as a cataloger (as you probably know) requires me to use OCLC’s WorldCat daily, through the Connexion Client. For you intrepid readers that skimmed that jargon-heavy first sentence, allow me to explain. WorldCat is the largest bibliographic database in the world - meaning that it has more catalog records in it than any other database. It is where I start when I catalog a book, as well as where I do the majority of my work. As we are an OCLC member library, we are expected to contribute records (and update our holdings) for every item we have in the library collection. As you can imagine, in the course of cataloging items in the collection, I come into contact with records of a wide array of quality, from very minimal level records, to records that (to me) seem to have too much information in them. There is truly no standard level of quality in the WorldCat database, and even records indicated to be of the best quality are often not exactly that. When my colleague Penny Baker at the Clark posted this tweet recently (in her usual humorous style), I came across OCLC’s report on the quality of records in the WorldCat database.
