William Herschel discovered NGC 4528 = H II-67 = h1331 on 15 Mar 1784 (sweep 174) and noted "vS but pB." His RA is 42 sec too small (several objects on this sweep have a poor RA). John Herschel made four observations (first on 11Apr 1825, his third sweep) with a range of brightness descriptions from "F" to "pB".

400/500mm - 17.5" (4/25/87): fairly bright but small, oval ~N-S, nucleus bulge, small bright core, stellar nucleus. Located 35' WNW of the NGC 4567/NGC 4568 pair.
