CURRENT AWARENESS SEARCHES ON CT, CBAC AND ASCA Available to Purchase

During the past year we have been one of the organizations participating in the Chemical Society's experiment on the use of routine computer searches of Chemical Titles (CT) and Chemical‐Biological Activities (CBAC) for current awareness. For some time we have also been subscribing to the Automatic Subject Citation Alert (ASCA), which is produced by the Institute for Scientific Information as a by‐product of the Science Citation Index. These three sources differ in their scope and methods, but share the same ultimate objective of providing a computer‐based current awareness service.
