There are two locations in Vivec - Hlaalu Records and Redoran Records - that are supposed to keep records for their respective Houses. If you actually look at the record books, they are all in-game books - dozens and dozens of them. Especially if you have some book jacket mod (like Better Books - and why shouldn't you?) this is immersion breaking.

So for those two cells, I replaced almost all the game books with five or so different version of generic record books for each house. Reading them gives you something like:
[These are official records and documents for House Redoran. Dusty, dull, and useless to you.]

No quests use the replaced books, and there were no skill books in either cell, so it should have no impact on gameplay.
