This may or may not be what the original poster had in mind: http://www.acm.org/classics
If it isn't, could somebody provide a link, please?
I went to Amazon.com and searched "Books" for "classics in software". The search results (the first 10 books), every single one of them were "Out of Print--Limited Availability" except for the last one -- "Not yet released."
Somehow I find this disturbing.
Maybe the EdYourdon book?

My grandfather recently gave me a copy of the book _Classics in Software Engineering_ edited by Edward Nash Yourdon, copyright 1979. -- DavidCary
Right on the copyright page it says
"This book was set in Times Roman by YOURDON Press, using a PDP-11/45 running under the UNIX operating system."
No doubt using troff.
