A full list is also available on application. Under the Select scheme, licences, Upgrade Advantage, media, and manuals are priced separately. The licences and Upgrade Advantage are issued in-house, and disks are copied locally. The software is provided by Microsoft on master CD-ROMs, and a new set arrives periodically. The latest software releases are not always available straight away under the scheme.
Some software is provided only on disks, and some only on CD-ROMs.
Under Select 4, licences may only be issued for the latest version of each software product, except where this version is more expensive than previous versions. Under the terms of the licence the end-user may run an earlier version of the software instead. Upgrade Advantage under Select 4, replaces Maintenance under Select 3. It allows the software to be kept up to date but does not imply any support. For approximately two-thirds of the cost of the licence, software may be put on Upgrade Advantage for two years until 31 December 1999.
