TABLE OF CONTENTS: 1) Introduction 2) New combined list of traditonal acronyms 3) List of ATT related acronyms 4) List of slightly non-traditional acronyms

-------------------------------------------------------------------- 1) INTRODUCTION

A while back I posted a list of acronyms(first edition) with expansion/definitions along with a request that I wanted more. Below is a compilation of what I had, and what people sent me.

I would like to thank the following people for contributing: Roger R. Gowland hvmga!rgowland Carl Deitrick iham1!cbd Dave Curry pur-ee!davy Rick Heli ucdavis!groucho:ccrrick Lynn Ihlenfeldt mmm!lynn ?????? elsie!sck Kevin Koch dec-elgar!koch Greg Noel ncr-tp!greg Maurice trwrba!suhre Lum Johnson osu-eddie!lum ?????? lsuc!msb Marty Olevitch wuphys!marty Mike D. Jones wuphys!mike Jack Applin hpfclg!jack Craig Werner aecom!werner

Here are some random comments in no particular order:

Several people suggested some books of precompiled acronym listngs. As I was to repost the second edition of the list to the net, I turned down the offers to avoid copyright entanglements.

One person(lsuc!msb) sent me about 120 corrections (typos and spelling) to the first edition (I doubt that I will ever know how to spell missile).

For a machine readable list of acronyms, it was unconscionable to forget to include CS.

A couple of people mentioned that some of the entries are really abriviations or word (laser, etc). Maybe I should ammend the subject line to include abbreviations. And since I have seen AAAAAA in several places now, whether it was real or fake originally, it is now real.

I added another 100+ to the list.

If people wish to send me more acronyms (please not a bounce-back of the first edition list), I may(?) get around to doing a third edition (if there are plenty of responses).

I hope people don't flame about this in net.sources. I take sources to mean general knowlege listings (which in a CS environ means programs). It is also in net.misc to followup on the original posting/request. If this really does offend people's sensibilities, send mail.

Much thanks to everyone, Scott Barthelmy ihnp4!wuphys!scott "I am a child of the unixverse."
