It will be necessary to have this revision completed by the end of 1998 so that it can begin to be used in Current Mathematical Publications in mid 1999, and in Mathematical Reviews and Zentralblatt für Mathematik beginning in 2000.

We hereby solicit comments and suggestions from the mathematical community to be considered in this revision process. These should be submitted by June, 1997. The preferred method of communication is by e-mail:

msc2000@math.ams.orgor

msc2000@zblmath.fiz-karlsruhe.de.(Comments and suggestions may also be sent to either one of us at the addresses given below.) We are eager that research mathematicians and scholars have input in this revision process as soon as possible.
