From Diablo Wiki
Books and writings are as common in Sanctuary as in any other world, and the writings of men, angel and demon kind alike numbers in the thousands. These are a few of the known works from the Diablo Universe.

A lot, but not all, of the material that sums up what we know of the lore about Mr D comes from "in-world" books, and as such is prone to fault and inconsistencies, like sources might be in our world. This is of course also a perfect way for Blizzard to keep most of the material "real" in terms of retcons and "canon" facts.
The fact these stories most likely were meant to indeed be "true" when it was written by Metzen & co ten or more years ago just makes it a little bit funny to us readers a decade later.
With an ever growing library of ideas that together sum up the Diablo Universe, inconsistencies are bound to happen, and as such, retcons will happen. Less interesting facts like specific years or months will fall aside to more interesting ideas such as fitting a multitude of creative works together as a cohesive whole.
All of a sudden, King Leoric was no longer a Northern Lord and he no longer ruled for decades in Tristram. Instead the pious lord ruled for a year or two and come from the East. Several similarly minor changes have taken place, and much of it explained as just errors by the individual authors of the books, as the author was an in-world scribe with his own knowledge and own motivations. Most famously hinted on by Abd al-Hazir in his Goatman entry, blaming much of the old lore's faults on corrupt Vizjerei mages wanting to improve their reputation after the horrendous Mage Clan Wars.
Most of these books have no known author and only comes with a few short paragraphs each. This of course makes sense from our real world point of view, as it would be a terrible waste of man hours to write a multitude of books that often overlap just to give some backstory to the game anyway.
The two primary sources of these books are from the Diablo I Manual, Diablo II Manual and Tomes. Tomes are ancient books spread in dark and dangerous places with surprisingly little useful information (considering they are each a whole book). Never the less, some pieces of information can only be found in Tomes.
A majority of these Book excerpts are collected in Diablo Wiki as a handy reference for anyone interested in lore. More books will soon be added, both from the Diablo I Manual as well as from actual Diablo novels and other references.
So, you got the intro peptalk, what are you waiting for? Go ahead and read some REAL Diablo literature, from people living* on Sanctuary!

Known Authors and their Works
There are several known authors of literature in Sanctuary and related realms. Many of the more interesting ones are of course powerful magicians or leaders of people. There is also Abd al-Hazir and his travels around the globe, which brings a lot of knowledge to us readers. Here is a list of known authors:
- Abd al-Hazir - Travelling writer, who have seen much of Sanctuary none else ever have.
- Akarat - Prophet of the Zakarum.
- Aust of Harrogath - One of the town Elders in the Barbarian town of Harrogath.
- Deckard Cain - Scholar and last descendant of the mighty Horadrim. While lacking magic skills, he has tremendous knowledge, and helps any inquisitive traveller or adventurer on their path.
- Kalan - Not much known.
- Nor Tiraj - Acolyte of the Horadrim.
- Ord Rekar - One of the Elders of Harrogath.
Works of Unknown Authors
- Prophecies of the Final Day - This book is a work of prophecies in Sanctuary. It's most likely located in one of the libraries of Caldeum, but exact information is currently unavailable.
- Encyclopedia Sanctuaria - As part of the Vizjerei or Horadrim libraries, it's a known encyclopedia about Sanctuary with brief entries about its lands and inhabitants (mostly monsters). Author is unknown, but it's possible it's Nor Tiraj.
Tomes & Books
- Main article: Tomes.
Tomes are in-game in the Diablo games with lore information. They are of course also books, but listed and indexed separately from "regular" works created on Sanctuary (or anywhere in the Diablo Universe). Their exact credibility or canonity is as debated as any other in-world book. Most of these lack a known author.
