Most online book sellers offer free recomendation and notification services when they add new items to their database.
Some publishers offer a similar service, or list new publications online.
By registering yourself with them you can be emailed when new material in your area of interest is published. At present the Library is unable to automatically generate lists of new books that have been added to the collection. It is hoped that this service will be available during 2000. New books are displayed within each branch on a regular basis.
