The NA-Net is a system developed to serve the community of numerical analysts and other researchers. The Na-Net provides two independent databases and a weekly digest to its members.
The NA-Net's email database knows the electronic mail address of each of its members, and is capable of forwarding mail to them. In addition, this database serves as the distribution list for the NA Digest (see below).
The NA-Net "white pages" is basically a directory service. It provides a way to exchange personal information among its members. Contained in the database are phone numbers, postal mailing addresses, research interests, affiliations, etc.
In addition to the two databases, the NA-Net also provides its members with the NA-Digest, a weekly collection of articles on topics related to numerical analysis and those who practice it.
