Here is a link to a USGS publication: Map Projections, a Working Manual, by Snyder. Can’t be downloaded, and uses the PDF plugin and not PDF reader.

Here is another source for projections:

G.Projector is a cross-platform application which can transform an equirectangular map image into one of over 100 global and regional map projections. Longitude-latitude gridlines and continental outlines may be drawn on the map, and the resulting image may be saved to disk in GIF, JPEG, PDF, PNG, PS or TIFF form.
