Debian 3.0r1 contains 7 CDs. From the READMEs:
The programs on the Binary CDs are ordered by popularity. The Binary-1 CD contains the most popular programs and the installation tools; it is possible to install and run Debian with only the Binary-1 CD. The other CDs, up to Binary-7, contain mostly special-interest programs.
And I am not bringing the NONUS version of disc 1 unless someone specifically wants that.
