The SDSS-DR16 Quasar Superset and pipeline catalogues are searched for
undeclared quasars which were concealed by or confused with other objects,
usually due to incomplete deblending. Forty such quasars with redshifts are
found and herewith presented. Also, 81 entries in the SDSS-DR16Q main quasar
catalogue are shown to be non-quasars, some also due to incomplete deblending,
especially “line poachers”. The deblending issue is discussed throughout.
