Have you noticed? Many more controlled headings in WorldCat

Three weeks ago my colleague Thom Hickey blogged about a project he started to control names in WorldCat. This is another example of leveraging the work done in WorldCat Identities to bring more headings under control in WorldCat itself. Rather than individual catalogers updating headings in a record manually, Thom describes a process where 8 headings a second are linked to their associated LC-NACO authority record.

At the time he wrote about the 63,489 Johann Sebastian Bach’s in WorldCat that were brought under control; last night it was 47,000+ Beethoven’s. Since the start of the project, about 5.5 million headings have been controlled, just over 20% of the 26 million “fairly easy” headings—personal names that match an authority record on multiple subfields.

So, how about it? Have any of you out there noticed?
