Libraries are rooms that must be opened with a key. They can contain at least one book, card or rune in them. The books are free to pick up.

The list of books that can be found in the library can be found here.

Libraries have a base 5% chance of spawning. Touching a book adds a separate 25% chance, for a total of ~29% in the following levels; the item does not need to be kept for the bonus chance to apply.

Contents[]

A Library can take one of the following layouts:[]

Notes[]

  • Removed in Repentance From the outside, the library is identical in appearance to the shop. One of the ways they can be distinguished is if Isaac has a mapping item such as Spelunker Hat Spelunker Hat or The Compass The Compass. Generally, the library will be closer to the spawn than the shop.
    • Added in Repentance The library now has its own door.
  • Once all books in the library pool have been picked up, items from the Treasure Room pool will spawn instead.
    • This can be achieved by repeatedly re-rolling the contents of a Library with The D6.
  • Libraries are particularly useful for acquiring the Bookworm transformation.
  • Added in AfterbirthChaos Chaos replace the books with items from random pools, allowing Isaac to get passive items without rerolling.
  • Added in Afterbirth † Maggots can spawn in the library.
  • Added in RepentanceNO! NO! now replaces all the books inside the library with passive items, with Added in RepentanceBook of Virtues Book of Virtues being the only exception.

Trivia[]

  • The music that plays in the Library is the same as the one played in ending 14.
  • This Isaac seed has 4 libraries up to depths 2 - EY4S A906
