An undistinguished collection. No originals, no Canadian authors and 10 books from the queen of soft core mid-century romance - Phoenix Press of New York. I don't know anything about the owners or employees of Derby.
Lush Lady by Gail Jordan (pseudonym for Peggy Gaddis [1895 - 1966]) was first published by Phoenix Press in 1949. Gaddis has too many other pseudonyms to list.
Highway Jane by Gordon Semple (pseudonym for William Arthur Neubauer [1916 - 1982]) was first published by Phoenix Press in 1949 as Passion's Highway. The author also wrote as William Arthur, Ralph Carter and Norman Bligh.
Borrowed Husband by Florenz Branch (pseudonym for Florence Stonebraker [1896 - 1977]) was first published by Phoenix Press in 1949 as Borrowed Love. The author also wrote as Thomas Stone.
