opening catalogues besides 1.e4
MCO is modern chess openings.

MCO stands for "Modern Chess Openings". You'll often see it written, MCO-15 (Modern Chess Openings, 15th edition). That's the latest edition. Basically, MCO is the bible of chess openings.
If you want books that explain openings in detail, take a look at these ones: http://www.chess.com/equipment/chess+books/openings
This one caught my eye: http://www.chess.com/eq/chess+books/ideas-behind-the-modern-chess-openings-attacking-with-white2
I haven't read it myself, but it looks like the kind of book you're looking for.

Anyone know of a good opening book/ catalogue listing non e4 openings? Thanks for any ideas
