Below you will find titles housed at HathiTrust that were published in 1928 and now have full view access available in the US. The data comes from this collection. The titles are sorted by popularity, meaning the works at the top and in descending order are the ones mostly widely held by the most institutions, according to Worldcat. By Matt Miller
You see titles like Moby Dick in this list, which have long entered the public domain, because an edition or translation of the work was published in 1928. HathiTrust works on volumes so if a new publication of an old work happened in 1928 it will show up in this list.
The 2000 top literature list is an attempt to filter down to mostly widely held novels and other fiction, not things like government or institution reports that are widely held. The number 2000 is the number of titles that are held by over 100 institutions.
The 1000 list is everything, including annual reports etc, the number 1000 is arbitrary.
I used a popular generative machine learning API to produce book covers for these titles. I wanted to make browsing the page more visual and I think it is a rare example where generative image generation is a valid use case. The images are not always very good or make any sense contextually but if you like them you can download them with or without the text overlay, CC0 license with metadata in this zip file (6GB).
