Today marks the 40th anniversary of the launch of WorldCat, the world’s most comprehensive online library database (and as I’ve told scores of USI students, my personal favorite). In addition to the subscription version of WorldCat, which is available to all USI students, faculty, and staff, there is now a free version, known as WorldCat.org. The database currently has in excess of 240,000,000 bibliographic records, representing 2 billion items of all types held by over 72,000 libraries worldwide. (See the database’s stats sheet.) It’s always fascinating to “Watch WorldCat Grow” in real time. For the complete text of the press release announcing the anniversary, click here.
