Wow.  There's more stuff in pockets than this, but it's different to see it all in one place.  He'll spend a while wandering through, looking at signs and titles without picking anything up.

There are sewing patterns and books of recipes. Books about animals and plants, physics and chemistry. Fairy tales and fantasy and poems and a lot of kids' books.

Can he find any slice-of-life about what it's like to live in Hollow Grove?  It's fine if it's a kids' book.

There's a Local section with people's memoirs and slightly polished diaries and stuff.

...He thinks he'd prefer fiction, if there's any.

There are a couple recently written fiction items that seem like somebody's attempt at distilling their parental advice to their children into book format which are about a child growing up in Hollow Grove and learning to get along with others and tolerate doctor's appointments, and going to school and going mushrooming and conquering his fear of bees, and stuff.

What is taught here about how to get along with others?  And also like, what are some objects that exist in the background and that he might or might not be familiar with.

This book emphasizes that you must be Considerate and think about how you might be affecting people - being noisy at night is not considerate! Getting them a present you didn't put any thought into isn't considerate! Etcetera - and there are smokers to make bees chill out, and various kitchen gadgets, and musical instruments, and paintbrushes, and dogcarts, and cats, and potter's wheels, and doctor tools of assorted kinds.

They don't have good soundproofing; that's good to know.  And obviously everyone is much more on the same sleep schedule...

Pottery wheels!  Bee objects!  Interesting.

...What sort of doctor tools are there.  In particular what ones might have been used on him.

This book mentions tricorders, injectors, bandages, pills, and flashlights for looking into one's ears and mouth.

Do the bandages seem to be just plain strips of cloth??  Or is there anything about them to make people heal faster.

They're sticky strips of substances that are not wholly cloth. They keep irritants out of a healing wound, and keep topical medications in place.

That's strange, but most importantly not an obvious indication of magic.  ...Are there any mentions of restaurants, in this book?  Do they seem to exist?

There are restaurants! There's a sandwich place mentioned in specific.
