Help the librarians…


We need proofreaders! Digital processing of books is still a difficult task because errors other than those of the author can be introduced. Proofreading consists in:

  • Tracking misspellings, grammar errors, misprints…
  • Correcting any error (page interchange, caption misplaced, layout…).
  • Comparing with the original to make the copy as identical as possible, except the author's errors and the possible corrections that he published.

NB: It is a long and heavy work. Do it only if you are sure to conclude! Its is better to proofread carefully a few pages than to proofread badly the whole book.

You find a mistake (or several…)

  • Be sure that it is really an error by comparing with the original (file …_O.pdf)
  • send us by mail ( the description of the mistake and the correction.

NB: Knowledge progress since the work was published may prove that the author was wrong. This is not a “mistake” that deserves correction however.
