First edition, first issue, possibly a later impression. In this issue the title page is headed ‘Manuels Roret’, the author’s name spelled ‘Berthiau’ and it is undated. The second issue title page is without the heading, the author is spelled ‘Berthiaud’ and it is dated 1837 (the copy in the BN on Gallica has advertisements dated June 1837). Copies with the first issue title page are found with advertisements dated 1880 or 1885; both issues were very likely printed from stereotype plates. In this copy the half-title and advertisements – if there were any – have been discarded by the binder. References. Bigmore and Wyman I, p. 52; Stijnman 029.1, both describing the issue dated 1837.
¶ The most extensive rolling press manual ever published and the first original manual since Bosse (1645) – above. Pierre Boitard explains in his ‘Avertissement’ that he edited material supplied by Berthiau, an experienced copper-plate printer. Both wooden and iron presses are described and illustrated, making this the first published account of the iron rolling-press and its operation. It is the first manual to discuss the use of intaglio illustrations in printed books.
Berthiau travelled to England to investigate copper-plate printing in London, where plates for books were apparently much better printed than in Paris. Boitard attributes this to the higher price of books in London. In his long ‘Appendice de l’éditeur’, he makes proposals for the improvements in the economy of copper-plate printing.
Many of the ‘Manuels Roret’ were first published as ‘Manuels’ with revised editions as ‘Nouveau Manuels,’ but there seems to have been no earlier edition of this manual. This issue, which I take to be the first, is undated but the date can be inferred from the fact that Boitard says that Bosse’s Traité was published 193 years ago in 1643, giving a date of 1836 (actually the Traité was published in 1645; Boitard repeats his error on the following page). The priority of this undated issue seems to be confirmed by the fact that the author’s name is here consistently spelled Berthiau (on the titlepage and pp. 4 and 5) while in the 1837 dated issue it is Berthiaud on the titlepage but unchanged in the text which is printed from the same setting of type (presumably from stereotype plates).
