Note: One front page of the 2008 Alice omnibus (ISBN 0199536341, trade paperback format) notes that the series is now more than 100 years old with more than 700 titles, and mentions "the pocket-sized hardbacks of the early years". Thus the publisher Oxford University Press considers this series identical with The World's Classics, founded by Grant Richards in 1901. OUP considers the 21st century Oxford World's Classics Hardback Collection a subset of this series.
