Model
WorldCat operates on a batch processing model rather than a real-time model. That is, WorldCat records are synchronized at intermittent intervals with the underlying library catalogs instead of real-time or every day. WorldCat shows that a particular item is listed in the catalog of a library, but cannot indicate if the item has been borrowed and is therefore unavailable for access by other patrons. Alternatively, WorldCat allows participating institutions to add direct links to WorldCat to their catalog entries for a particular item.
