Locations of all tomes to permanent increase stats

I noticed that there is no such guide yet, so i thought to quickly write it down.
There are several tomes hidden in BG1. Each tome increases one stat by +1 permanently.

Strength:
Candlekeep Catacombs (chapter 6) Its in one of the sarcophages.

Constitution:
Its in the siren cave in the lighthouse map. To get there from Beregost, travel West, then south, then west. The cave is in the top left part of the map at the shore.

If you are playing a fighter type with 18 Constitution and want to profit the most from this, you actually can sneak into the cave with Imoen (make sure she can carry it, tomes are quite heavy) right after the start of the game so you get 19 Con before you level up the first time to get more HP.
Make sure she has the oil of speed with her to sprint out after getting the book. Also watch for traps. (She can detect and defuse them, even at lvl 1)

Dexterity:
In a barrel behind the merchant "Black Lily" in the thieves guild of Baldurs Gate (city). You can just loot it without raising an alarm. (chapter 5)
The thieves guild is in the east part of the city (the map where you first enter it)

Intelligence:
Located at the top of the tower of Ramazith, in the northern part of the city. (chapter 5)

Wisdom:
There are actually 3 tomes of wisdom available:

One appears in Baldurs Gate (city) during the quest where you are tasked to cure Marek from his curse. Your task is to bring the tome to the temple in the dock district in exchange for Mareks cure, but you can trick the priestess to give you the scroll before giving her the book and then simply keeping it without big consequences (you have to kill the priests though)

Two is located in the Candlekeep Catacombs just like the the tome of strength. (chapter 6)

Number three is in Durlags tower, in the 3rd floor of the upper levels. Watch for traps!

Charisma:
In one of the 3 caves in the southern part of the gnoll fortress map. From Nashkel mines travel west, travel west and travel west to get there.
