OSRIC is -- especially in its Black Blade Publishing version -- it's probably a little too impressive to be used as a player's reference book. At nearly 400 pages, OSRIC includes a lot of material intended for use by the referee rather than by players. That's where the OSRIC Players Reference comes in. It strips OSRIC down to the 140 pages that players require to generate characters and to play the game at the table.
You can get the PDF version of the book for free at the link above. Alternately, you can get a print version from Lulu.com in either a regular or pocket size. Both are inexpensively priced and for use with the current version of the hobby's first retro-clone. If you're using OSRIC at your table, the Players Reference is definitely worth taking a look at.
