New MARC Usage Data Available

visI just finished updating my “MARC Usage in WorldCat” web site that summarizes and reports on how MARC elements have been used in the 333,518,928 MARC records in WorldCat as of 1 Jan 2015.

Not surprisingly, the totals for new fields such as 336, 337, and 338 have shot up, from some 9-10 million occurrences in January 2014 to 40-50 million occurrences in January 2015.

Also, it appears that well over 33 million records have come in through the Digital Collection Gateway.

As always, if you wish to see the summarized contents of any subfield just let me know. And don’t forget about the visualizations (pictured).
