House Decoration:
Rémon, G. Soixante planches de peintre
décorative. n.d.

and the supplementary references are

Decoration, House. See House Decoration.
Ornament. See also House Decoration.

If the title of this book were printed "60 planches de peintre décorative", and the title had to be transcribed in full, the language of the original must be followed, and not a hybrid title given, as "Sixty planches de peintre décorative".

The third book, being upon ornament in general, receives an entry accordingly

Ornament:
Lehner, J., &c. Neue Dekorations-Malereien
im modernen Stil. [1904]

No further references are needed beyond those already given to the first of these three books. It would be literally correct but none the less pedantic to convert the "&c." of the above entry to "u.s.w." (und so weiter), as

Lehner, J., u.s.w.

and such a procedure is not recommended.
