Smith, John: A catalogue raisonné of the works of the most eminent Dutch, Flemish, and French painters: in which is included a short biographical notice of the artists, with a copious description of their principal pictures : a statement of the prices at which such pictures have been sold at public sales on the continent and in England; a reference the the galleries and private collections in which a large portion are at present; and the names of the artists by whom they have been engraved; to which is added, a brief notice of the scholars & imitators of the great masters of the above schools (Part 6) (London: Smith and Son, 1835)

In compliance with a wish expressed by several
subscribers to the work, and the objections of others,
the Author’s estimate of the probable value of pictures
in private collections will be in future omitted, except
in such instances as where they have been sold greatly
below their present value, and such estimation will
hereafter be confined to those only in public galleries.
It is hoped that this and the two following volumes,
will show the earnest desire of the Writer to fulfil the
expectations of the subscribers: the eighth and last
volume will contain a large Supplement of omissions in
the preceding, and correction of such errors as have
naturally occurred in a work of so multifarious a
character, and the first of the kind undertaken.
