Official Civilization II Documentation.
The documentation that comes with Civilization II is inadequate.  Most of the information you need can be found someplace, but it is scattered across the printed manual, the terrain supplement, the wall poster, and several entries in the online Civilopedia.  I have collected into one file the information contained in these various locations.  I have added a few snippets of useful information as well.  The file is in pdf format.  You are free to download it, print it, and distribute it to your friends.


Civilization II Fanatic's Manual.
I have copied the "War Academy" text from the superb web site Civilization Fanatics Center and converted everything to pdf format.  I have made a few minor editorial changes to make some tables and other text print on one page or something similar.  I also have corrected a few typos.  Otherwise, the text is the same as what appears on Fanatics web site.  The Fanatic's Manual contains excellent discussions of strategy, the way combat results are determined in the game, and so on.  The file is as large as it is because of three figures.


Two useful websites:

    Civilization Fanatics Center (http://www.civfanatics.com/civilization2.shtml) is an outstanding site that has extensive information on the original Civilization, Civilization II, and Civilization III.

    Apolyton Civilization (http://www.apolyton.net/civ2/) is another excellent site that has extensive minute details of how to play Civilization II.  Lots of practical discussion and advice contributed by users.
