Guillaume Bigourdan discovered IC 4528 = Big. 423 on 23 May 1898. His position corresponds with CGCG 248-046 = PGC 53658. Nevertheless, MCG, CGCG and PGC fail to identify this galaxy as IC 4528. Instead, MCG and PGC misidentify MCG +08-27-049 = PGC 53607 as IC 4528. This edge-on galaxy is over 10' NW of Bigourdan's position.
