It lets you sort the encyclopaedia. e.g. only to filter units currently available, or in unit class order. See the Game Guide "CD-Extended Features" link then scroll down to "Encyclopaedia Sort Screen" sub-section.

The Encyclopaedia always allows you to see the other nation's units - press the nation flag and change from the nation selector screen. (This is described in the Game Guide, "Encyclopaedia screen", paragraph beginning "Select a new nation from those active at this date by pressing on the existing flag in the centre of the screen.." which is right at the start of the Encyclopaedia help)

The Game Guide is the game's manual - easiest way to get there is to load the GameOptions menu, select the "Help" tab and press the "Read the Game Manual" button. The GG will then appear in your HTML browser, with a frame of navigational links in the left column, GG text in the RHS column.
