This isn't an edit-heavy mod, but there are a few additions to various interiors.

WARNING: THIS DOC MAY INCLUDE SPOILERS IF YOU'RE TRYING TO WORK OUT THE LOCATIONS OF THE UNIQUE BOOKS

(note: this contains the edits for the upcoming update, so if you read it before the 1.1 release then some of this stuff won't be there yet)

Apocrypha has a few here and there, but I've not seen any mods that really edit the Apocrypha dungeons much so I'm going to assume these are fine for now. Each black book has its associated 'complete' book next to the perk chooser book thing at the end, except for Epistolary Acumen which has it near the beginning, and Waking Dreams which has it in a container at the Summit of Apocrypha (so it doesn't go flying off the tower in the Miraak fight).

Anise's Basement - One journal

Yngvild - One book added to Throne Room.

High Hrothgar - two books added to existing bookshelves.

Hob's Fall Cave - two or possibly three books added to one of the bookshelves.

Soul Cairn - One chest added to a floating island close to one of the Keepers

Temple of Miraak - Three book stack containers added just behind 'Waking Dreams' book

Sky Haven Temple - Three books added to bookshelf

Dimhollow Crypt - One satchel next to Vigilant Adalvald

Blue Palace, Pelagius Wing - One book added

Blackreach, Debate Hall - One book added

Fort Frostmoth - One book added

Mount Kilkreath, Catacombs - One chest added
