This article in Information Today outlines upcoming changes in Open World Cat and mentions that OCLC will begin charging Libraries to participate in OWC.
Some of the services
Serials--a union catalogue of electronic journals and sources. Libraries will be able to register resolvers so users can connect directly.
Reference--libraries that offer virtual reference can have a icon added to indicate this when users search for libraries that hold an item
Book Buying--users can buy books direct from Baker & Taylor, if a home library is named by the buyer, then the library will get a portion of the sales as a credit on their OWC invoice
