Okay so I delved a little deeper into Ruby's goodreads and her 150 'books' read.
Her average book length was 249, with the shortest being 13 pages and the longest being 744 (which was David Cameron's autobiography
).
I think it's completely fine to put short stories on it but she's put
everything as a book read, including essays, single poems, and the majority of what she's read appears to be children's literature. She read 37,358 pages overall.
I read 150 books in 2020, my average length was 335, my shortest was 12 pages (yes a short story lol) and my longest was 803. I managed 50,266 overall. Just for some perspective. Same amount of books, significantly more pages overall.
Also I love libraries and what ruby said pissed me the fuck off, I grew up forcing my poor mother to drag me and my younger sister down there once a week at least, because we couldn't afford to spend fucktons of money on books so libraries were how I got into reading. They're such an important resource and I continue to use them as an adult.
