Ashurbanipal

Ashurbanipal (アッシュールバニパル) is the Grand Library that's located at the tenth floor of the Great Tomb of Nazarick.

Background
Most of the books in the library of the Great Tomb of Nazarick are mostly summoning books. But in reality, there is no need to acquire so many of such books, as using every single resource from Nazarick, it still cannot summon about one tenth of the amount of monsters. Therefore, the reasons for gathering so many books were to acquire books that do not need to pay a price and also to hide important magic items by blending them among the ordinary ones.

There are three major corners in the library. The areas are the corner of wisdom, the corner of knowledge and the corner of magic.

The books in the library can be mainly put into five categories:


 * The first category are a collection of recorded monster data, which was required to summon said monsters such as mercenaries. There were three types of monsters inside Nazarick. The first type consisted of monsters that were created in a similar manner as player characters. The next type consisted of automatically spawning monsters that were under level thirty, and the last type consisted of monsters that were summoned as mercenaries. Mercenary monsters needed to be summoned using a book, a special summoning ritual and adequate amount of gold. Thus, they could not be summoned without a book.


 * The second category are magic items, which certain data crystals could only be imbued into a book-shaped object. Items shaped like books usually tended to be single use magic items. The difference between a scroll and a book was that while scrolls could only be used by certain classes, anybody could use a book.


 * The third category are event items, which it was not uncommon for an item to be required, when advancing into a special class. These can be items required for class change, items for race change, learning new magic and books studying about skills, legends. Additionally, some of these items came in the shape of a book. Even Ainz needed a “Book of the Dead” when he evolved from a Skeleton Mage into an Elder Lich. There were other books such as “Bibliography of Weapon Research” or “Anecdotes of the Four Great Spirits”. There were also books that taught new magic.


 * The fourth category are a cosmetic skin database, which these books contained with them are the cosmetic skin data of objects like swords, shields and armour. Thus, players with certain blacksmith skills could put new skins on items with this and other appropriate materials.


 * The fifth category are novels in the form of book shaped items. Normally, there would be old and classic literature whose copyright ran out a long time ago, but there were also background stories distributed by the development team and original novels written by players in YGGDRASIL. There was also fanfiction based on the worlds of YGGDRASIL or game guides in the form of diaries or novels.

Layout

Resembling something similar to an art museum, even the ceiling is adorned with beautiful painting. There is also a second floor in the library with a lot of glass shelves so orderly placed. It is very much this way that almost all of the shelves cannot be visibly seen in a single glance. There were also several smaller rooms designed for specialized uses and the individual rooms for the staff.
