May wrote five large (many thousands of pages) colportage novels, which he published either anonymously or under pseudonyms between 1882 and 1888.

Das Waldröschen (1882–84, a part was later revised for Old Surehand II)
Die Liebe des Ulanen (1883–85)
Der verlorne Sohn oder Der Fürst des Elends (1884–86)
Deutsche Herzen (Deutsche Helden) (1885–88)
Der Weg zum Glück (1886–88)
From 1900 to 1906, Münchmeyer's successor Adalbert Fischer published the first book editions.
These were revised by third hand and published under May's real name instead of pseudonyms.
This edition was not authorized by May and he tried to stop its publication.
