For which processor?  (Sheesh!)

If you're concerned with the Intel x86 processors, why not go straight to the source?  You can get any of the Intel reference manuals right from their website.  Volume #2 of the Software Developer's Manual contains a complete reference, including descriptions, addressing mode encodings, and timing information.

It's at.

It's in Adobe Acrobat format at http://developer.intel.com/design/PentiumII/manuals/243191.htm.

The site also has information on getting printed copies of the book from Intel's Literature Center.

The help file "Opcodes"(83k),in the MASM32 package, contains all of the opcodes,their mnemonic, and a description of each instruction.

It can be found at:
http://www.pbq.com.au/home/hutch/DOWNLOAD/Opcodes2.zip

Your other option is to download Mnemonix(11k). Mnemonix is a popup program with over 900 hex opcodes and their corresponding mnemonic.

Get it at:
