Players looking to add more personality to their homes should keep an eye on the Travelling Book Shop vendors: Solelo in Stormwind, and Lonalo in Orgrimmar.
Both vendors offer a rotating selection of decorative books, and their selection changes every day. This makes them a surprisingly useful stop on your daily circuit for two reasons:
- A steady source of Housing XP. Purchasing new decor grants a first time collection bonus of 10 XP towards your House Level.
- Library building. If you’re aiming to create a full library, these daily book offerings can add up quickly.
Lucasqs on Reddit has shown us just what these larger library builds can look like, with their Dalaran-inspired ceiling library. They used 125 
Secretive Bookcase Walls to assemble a soaring spiral of shelves—an architectural illusion that feels like it belongs in Karazhan itself.
If you’re going for the lore-rich aesthetic—or you’re planning an ambitious mage tower library—these vendors deserve a spot on your daily list.
