Fast Facts: Roy Tennant on “The Most Edited Records in WorldCat”

Roy Tennant at OCLC Research has yet another interesting post for all library data geeks now available on the blog.

This time Roy does some data mining and provides us with a list of the most edited records in the WorldCat database.

After explaining how this research came about Tennant writes:

…I looked into how often WorldCat Records have been edited and by whom. I will be blogging about this in an upcoming post, but a small slice of this investigation was a closer look at the records that have been edited a lot. Since we keep track of the cataloging symbol of every institution that has edited a record, these can stack up for records that require updates on a regular basis — in other words, serials.
All of the records for these serials were edited more than 60 times over their life in WorldCat, and in no particular order:
13 serials are on the list, many of them serials published by the U.S. government.

Here are a few of the titles on the list. You can find the complete list here.

  • Books in Print
  • Encyclopedia of Associations
  • US News & World Report
  • Occupational Outlook Handbook
  • Statistical Abstract of the United States
