Huge: 32 stories / 621 pages. No date or editor listed in credits or anywhere on the book - I got the date from Contento's listing. I have most of the magazines that these stories came from - and while I have not read them all, I can tell you this is a pretty good sampling of Astounding/Analog from 1939 to 1972, and makes an effort to include some uncommon stories that you won't have seen before. If you want to know what is meant by the term "Analog story" - this anthology will show you. See scan #2 for the table of contents.
