Your campsite contains a lovely 3-shelf bookshelf -- handsome mahogany inset with mother-of-pearl mystical runes! It's got a shelf for Tomes, a shelf for Librams, and a shelf for Grimoires...
Tomes: Tomes contain powerful spells. So powerful that you can only use one Tome per day, lest you become absolutely corrupted by the absolute power.
Librams: Librams also contain powerful spells. Each time you use a Libram in a day, it'll take you more and more energy to use another one. Or the same one again. You'll get the idea once you start using them.
(Your bookshelf doesn't have any Grimoires on it.)
Notes
The bookshelf will only appear in your campground if you have used at least one Tome, Libram or Grimoire.
The bookshelf is not affected by Hardcore or Ronin restrictions. However, it is not visible while in Bad Moon, although it is currently possible to access the bookshelf through direct linking. Originally it was possible to use the books normally this way, but this was soon fixed.
The MP cost for summoning your nth Libram item is 1+(n*(n-1)/2), or 1+(1+2+3+...+(n-2)+(n-1)). This price resets upon rollover and ascension.
