[gutvol-d] DP crisis?

Does DP have a post-processing crisis? With thousands of volunteers texts flow regularly through the OCR and first phase quickly. However there are several thousand books that have been in post processing over a year. Many of these are hard, but many are plain text. Is it appropriate to re-scan a book to start the process over again hoping for better luck? One could clear another edition, etc. N Wolcott nwolcott2@post.harvard.edu
