This list features the cream of early 20th century literature worldwide. It includes many childhood classics and is a concentrated blend of 6 other challenges, as follows:
--- 3 are titled "Literature in the 19..s", and were originally published by a 'private user' at the start of 2021.
--- the other 3 are of the form "The Chronology of American Literature in the 20th Century: 1900-1909" and so on, and were published by me in 2019.
Criteria for inclusion in this subset were high relative popularity, high average ratings, good reputation of the publisher (e.g. NYRB) and a small dose of favouritism on my part.
