- This replacement name for a formerly lettered crater was provisionally introduced on LTO-63C4 (December 1973). It was approved by the IAU "as assigned" in 1976 (IAU Transactions XVIB). Two other provisional names on the same map (named for literary authors) were rejected. - Jim Mosher
- Schubert B (the IAU's Back) was the same crater which was once called Febrer by H.P.Wilkins and P.Moore.
