Pretty much a book about books; each book recommended had it's own page along with a description of the book and which patron to recommend the book to. I picked this up at the library because I decided that starting in 2018, I will be working on my masters degree in library and informational sciences (right now I am just deciding on where to apply and what requirements I need to meet). So I figured a book by a librarian who surveyed other librarians about what they recommend to their patrons can come in handy.
And yes, it is handy, but most of the books aren't to my taste. However, I have to give credit to the author for the balance in diversity in the books she chose to highlight in this book - whether from authors of color, to authors from the LGBT* community, books about mental illness, disability, social issues are all there alongside more well-known authors/books. The author also chose to devote a chapter to audiobooks and another to graphic novels, so she wasn't snobby about format. There is also a chapter on YA novels, with the caveat that these YA novels would be good fits for adult readers who enjoy YA, so she wasn't snobby about patrons' reading tastes either. The book did lean more to fiction than non-fiction, but some recent non-fiction reads were recommend for the writing styles were as engaging as some fiction reads.
There were books from the cannon of English Lit (Shakespeare) and modern classics (O. Henry), but also some works dating post WWII all the way through to the early 2010s. Alas, no genre specific chapters were written, so no romance, mystery, sci-fi books were recommended - the author stayed pretty firm in mainstream fiction/literary fiction section of the library. Still I made a list of the books she recommends and that seemed interesting to me (there were a few that I have already read) so I could add them to my TBR pile.
