What are the locations of the Act I lore books needed for the achievements A Quick Study, Taking Notes and Historian of Tristram?
A Quick Study
Adria's Journal: Leah will drop this after you fight Captain Dalton in Adria's Cellar.
Lachdanan's Scroll (all parts): These drop from scribe's lecterns found throughout the cathedral.
Leah's Journal (all parts): All pages can be found in Leah's room on her desk. New pages are activated as you progress through the quests.
Leoric's Journal (all parts): These can be found on pedestals in the Royal Crypts, Leoric's Manor, or the Hall's of Agony.
Farmer's Journal: In a satchel that spawns on the north end of the Fields of Misery (up a short flight of stairs - shares a spawn with Tinker's Hovel & Pillaged Home).
Scabbard of Talic the Defender: Spawns when doing the event on level 2 of the Watch Tower (Northern Highlands) - look for Vendel the Armorsmith.
Deckard Cain's Journal (all parts): Found in Deckard's home on his desk; the second part shows up after you start Sword of the Stranger.
Adenah's Jottings: Found in the House of Curios (Fields of Misery) near the bed.
Hermit's Ravings: Drops in a satchel that spawns somewhere in the Caverns of Araneae.
A Prisoner's Journal: Drops after you free Merhan in a random event found at the very end of the Halls of Agony (the large area just below the door to the Highlands).

Scoundrel's Journal: In a satchel in the Fields of Misery near the trail to the Old Mill.
Kingsport Bill: Drops when you talk to the scoundrel about his origins.

Wandering Tinker's Diary: Inside the Tinker's Hovel in the Fields of Misery.
Notes of Urik the Seer (all parts): Satchels found inside the Cave of the Moon Clan.
Priest's Contemplations: A satchel along the lower fork at the start of Wortham. Both parts drop from the same spot, so you need to do the quest twice (or leave your game and resume).
Mira's Letter to Haedrig: Drops in a box near Haedrig's smithy.
The remaining books are all found in an Old Keepsake Box that spawns along Old Tristram Road or in The Old Ruins. You will need to come back several times to get all the books:

Command from Cultist Grand Inquisitor: On a Musty Lectern in the Halls of Agony.
Reply from Cultist Grand Inquisitor: Same as the command; you will probably need to come back to find the reply.
A Page From Lazarus's Grimoire: At the bottom of the Halls of Agony level 3, watch the cutscene about Queen Asylla.
Orders from Maghda: Drops from the horde of mobs just inside Leoric's Manor.
Villager's Journal: In the keepsake box in the ruins of Old Tristram (Patch 1.0.3).
A Summoner's Journal: In the Southern Highlands, to the right of the map, there will be a small set of stairs to a cultist chanting. (Random spawn)
