From what I can gather with my 'less than a couple days' experience with the mod, it allows your Artists to produce items with a quality rating that your colonists can read for recreation, but requires multiple workbenches to produce all products.

Tablets at the Stonecutters table (Reaction uses intelligence skill)
Scrolls at the Writers Table (Modded workbench) (Art)
Books and Journals at the Typewriting Table (Modded workbench) (Art), which require pages from the Papermaking Station (Also Modded workbench) (Art)

You can then store these in specialized storage containers included in the mod and in your colonists free time they can walk up to it and take a book which they will either read at the shelf or take it to a nearby chair and sit in while reading. Reshelving books seems to be hit or miss, so misses generate another haul job for your colony.

The mod makes 2 new recreation types, reading, and practice writing.

Skillbooks can't be produced as far as I can tell, but I have seen them in the trade screen a few times already.

Hospitality guests work fine with the books and typewriting recreation

Prisoners, having no recreation need to begin with, ignore it save Prison Labor with Art work enabled

@Rifter, thank you for that excellent summary!
