  • This project is distinct from OCLC’s collection analysis service

Distinctive aspects

Worldcat linking
WorldCat Linking

The OCLC Number is used to link the circulation records to the corresponding bibliographic record in WorldCat

  • For records with an obsolete OCLC No.; the obsolete OCLC No. is replaced with the current OCLC No.

  • For records lacking an OCLC No. which had either a unique LCCN or ISBN; that number is used to identify the corresponding OCLC No.

  • Records lacking any standard number were not be validated and were excluded from the study

  • Records from the 2007 circulation files were paired the 2008 to determine annual circulation

  • The resulting data set contained the circulation records for ~30 million different items

  • Approximately 93% of the records were validated; many of the unvalidated records were for non-book materials


The project is still “in progress” and the data analysis is incomplete

Results are preliminary; revisions and corrections will occur
