There are 2,885 plates in 11 volumes. The plates were never banned and became a cash-cow enabling further copies of the text to be published.
The plates though were themselves not without controversy. They were based on a project by the French Academy of Sciences and there were accusations of plagiarism.
The volumes of plates follow on from the Panckoucke edition of the Encyclopédie on the lower shelf.
