Comments on papers by Harding (MNRAS, 74(8)), and Melotte (MemRAS 60(5)) describing objects foundon the Franklin-Adams plates; compares with plates taken with the Reynolds reflector (Helwan Obs Bull. 9-15):
NGC 5507 is probably a mistake for NGC 5506, which is much elongated; NGC 5507 is round. [previously included in Class II-Spindle-shaped Nebulae]
Van den Bergh, S. (1961)
, Astronomical Journal, Vol 66, p566) notes that this galaxy forms a pure pair with NGC 5507 3.9 arcminutes away.

(Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads EON,BM,SLDIF,EQDKLN.
