Phoenix Games published 4 CT supplements that I know of (and have):
1. Spacefarers Guide to Planets Sector One - From the back cover:
"Spacefarers Guide has a brief description of 100 planets in the wastelands. Even the brief descriptions in the guide have cost many men their lives. If you are brave or foolish enough to venture into the wasteland may this guide help you, and the odd gods of the galaxy be with you."
front & back cover - 64 pages inside
2 pg star generation tables
100 worlds - Name, book taken from, author & publisher (in 1979). Stats: Physical (Population), Mental, Culture, Technological Level, Imports/Exports, Notes & very, very basic world information
2. Spacefarers Guide to Planets Sector Two (Rourke's Diadem) - From the back cover:
"At any rate, be warned: in the Diadem, truth wars with truth; if you would seek your fortune there, you must walk, fly, swim or crawl with extreme caution. May you learn something new every day."
72 pages
16 pages of library data & encounter charts
100 worlds - same format as book one, but a little bit more information.
3. Spacefarers guide to alien monsters - From the back cover:
"Enclosed I have listed some of the more interesting faunae, that reside on Second Empire planets."
64 pages
4 pages of encounter charts, more background information & bad artwork (think Judges Guild - on the other hand, this is what most artwork looked like "back in the day")
350 monsters with the following stats: size, speed, planet (type), weight, hits, & terrain (CT based) along with a short 1 or 2 paragraph description
4. Spacefarers guide to alien races - From the back cover:
"In it are listed most of our brother races who reside in Second Empire space."
64 pages
2 pg intro, 7 pgs of conversion charts, more bad artwork.
100 races, 1/2 page description
This is just a quick overview. What "Crunch" are you looking for?
