My first guide!

Let's get one thing clear - there is not an abundance of books that you can leisurely pick up. You need to strive for perfection in getting these books. At this time, this is a single playthrough achievement. If you are crazy enough to pursue this achievement, let this guide help preserve as much of your sanity as possible.

You need to try to get every last book; some folks talk about how there are oh so many lore entries in the game and you "only" need 45. Well, to the best of my knowledge from three play throughs, if you rescue Ag Center then there are at most 47 books that you can get that count towards the achievement as of the writing of this guide. One of those 47 was from a random encounter in California.

What if you rescue Highpool? If you rescue Highpool, you will still only miss out on 2 books - the Garden Journal and Lab Journal. You will still find the four "History of the Ag Center" books [Thanks to ValDeez for this information]. So, you should still be able to complete it with either choice. However, you may still need Ag Center for the gorilla suit, so if you are going for every achievement in a single playthrough, I would recommend saving Ag Center.

I am not sure if this is achievable if you fail to rescue either Ag Center or Highpool.

Many of these books are easy to overlook. This is an achievement of perseverance. You will not be able to come back and get books in Arizona when you leave, so make sure you have them all before you leave.

Finally, some books may require a certain Perception level to spot. For example, Napolean Blownaparte reports needing a Perception of at least 4 to spot the Garden Journal in the Ag Center.

What follows are notes on how to find 47 books.

I found 35 of my 46 lore entries here.

• (Temple of Titan - Underground) The Servants of Titan Part 3: Crate en route to launch computer

If you rescue Highpool instead, you will be unable to acquire the Garden Journal or Lab Journal, but you can still acqurie the four "History of the Ag Center" books [Thanks to ValDeez for this information]. However, you will gain two more books by rescuing Highpool, so you should be equally capable of completing this achievement either way:

• (Highpool) The Legend of the Red Ryder: Jesse-Belle's house, chest with alarm
  
• (Highpool) The Ballad of Bobby & Rex : Up top?

I obtained 11 of my 46 lore entries in California. I never found any lore item in Rodia, in spite of what has been recorded in various wikis on the interwebz.

Do yourself a favor and have Brother Thomas join your party so you can look at the four books in his inventory. Then you don't have to sweat finding them in/near the Bastion. I can, however, confirm that I did manage to find all four, so if you really don't want Thomas in your party even for a moment, then you can get by with searching around.

One of these lore entries is a random encounter, I think it may have been unavoaidable (e.g., a 0% chance to run away, but I am not certain if that was always true regardless of Outdoorsman skill); either way, if you read "Mannerites on nearby rooftops" be sure and have that fight.

• (Angel Oracle) Mr. Manners' Guide to Post-Apocalyptic Etiquette: talk to "Mannerite" woman near booktable with brochure on it (note: the brochure on the table is *not* the lore book). [Thanks to Xelian for this information and senornacho for confirming]
  
• (Hollywood) Welcome to Hollywood!: Medical crate in Swifty's sewer
  
• (Los Feliz) The Griffith Observatory: A History: Mound near building with statue out front
  
• (The Bastion) The Ten Commandments of James King: Medical crate behind refrigerator inside entrance of Penitent's pen
  
• (Bastion or Santa Fe) The Story of Samson Part 1: Crate on top of main Bastion building or in Brother Thomas's Inventory
  
• (Bastion or Santa Fe) The Story of Samson Part 2: Mound to the right of the Bastion main entrance or in Brother Thomas's Inventory
  
• (Bastion or Santa Fe) The Story of Samson Part 3: Somewhere in/near Bastion or in Brother Thomas's Inventory
  
• (Bastion or Santa Fe) The Story of Samson Part 4: Medical crate near Bastion Radio Tower or in Brother Thomas's Inventory
  
• (Seal Beach) Your Golden Future: When you enter Seal Beach, circle around to left into cul-de-sac by construction equipment; in crate
  
• (Seal Beach - Inner Compound) The Gospel According to Matthias: You pretty much walk out right by this crate in the Dugan fight
  
• (Mysterious Shrine (SW-most)) Blood-stained journal [1 of 2]: On corpse
  
• (Random Encounter) Stoll's Journal: You will have a random encounter "Mannerites on nearby rooftops" and find this on Stolls after you kill him

You may notice that there are no entries for Angel Oracle or Rodia. That's because, in spite of suggestions on the interwebz, I could not find any nor has anyone responded to my threads about those books. Ergo, I assume they are no longer in the game or something special must trigger their appearance.
