With nearly 300 million bibliographic records, WorldCat is the largest aggregation of shared library data in the world. With access to this data on a large parallel processing computer cluster, OCLC Research has undertaken a number of projects to maximize its value by processing the data in interesting ways to create new services. Work is also being done to report back to the library profession on how the MARC standard has been used over the last 40 years. Roy Tennant describes some of these efforts as an illustration of the power of mining shared library data.
