about the support bulletin
The support bulletin is a quarterly technical journal published by NeXTComputer, Inc. Its goal is to provide timely technical information to help you better support your NeXT network or user community. 

Each support bulletin includes a floppy disk that contains an electronic version of the bulletin and NeXTanswers, a comprehensive library of technical information. The disk is designed to be used with the Digital Librarian application so you can easily access information on specific topics by searching for keywords.

NeXTanswers provides responses to common (and sometimes uncommon) technical questions. Formatted as question-and-answer pairs, topics include system administration, programming, and NeXT applications.

If you'd like to subscribe to the support bulletin or inquire about subscriptions, please use the order form called order_form.ps found in this directory.

If you have editorial suggestions or comments, we'd love to hear from you. Please e-mail us at support_bulletin@next.com or write to:
