I am pleased to note that we have updated the OCLC Top 1000 list.
This is a list of the most widely held works in WorldCat, which in turn represents the holdings of many thousands of libraries around the world. A work brings together the various editions, translations and so on of an item. Naturally, the list is rich in classics, works with long and varied publishing history.
The entries link through to OpenWorldCat - why don't you write a review!
Note: we use our FRBR algorithm to create the work sets.
