up lit noun [U]
/ˈʌp lɪt/
a literary genre comprising books that make the reader feel optimistic

A bruising year dominated by political and economic uncertainty … has, publishers say, kickstarted a new trend they have have branded “up lit”. In contrast with the “grip lit” thrillers that were the market leaders until recently, more and more bookbuyers are seeking out novels and nonfiction that is optimistic rather than feelgood.

BookTuber noun [C]
UK /ˈbʊk.tʃuː.bəʳ/ US /ˈbʊk.tuː.bɚ/
someone who posts videos of book reviews on the social media site YouTube

Print reviewing and vlogging are two very different things. BookTubers make excellent reading guides and they’re happy to chat about the sort of stuff usually ignored by print critics such as the look (and even feel) of books. There’s a great deal of bookish fun to be had out there on YouTube.
