I'll only spoiler the things that you might not get from the description of the items:

Magazines are supposed to give the people a career boost (Office Professional, Kitchen Professional, Workshop professional).

There are story books that let the parents read bedtime stories to the kids.

There are encyclopedias that have an effect on likes and dislikes, as long as your peep doesn't have too many of either one.

Desensetizing Kits remove a dislike from a peep.
