For the love of god...... Use MFR Enchanter for enchanting books it can give you upto 4 yes FOUR enchants on a single book and does not use your XP.
Here's how...
Get any tier 5 soul shard (cow, pig, chicken or any mob) set up and 10 x 10 area and wall it in, then take 4 MFR Grinders and position one on each side of the wall so that all the area is covered. Then connect each grinder to a BC power system (it uses a fair amount). Put a Relay next to each grinder to collect mob loot (yes you get the mob drops too) and pipe this back to your storage area. Connect a liquiduct to each grinder and then back to a tank.
Turn on system and mobs get killed, you get the drops, and the mobs get ground into "mob essence" which you store in a tank.
Take a MFR enchanter and pipe in the mob essence, connect it to a power source and feed it books.
Try it .. you'll wonder why you never did this before, yes it uses a lot of power but you end up with dozens and dozens of enchanted books, most of the time with multiple enchants on a single book.
