Happy to let you know that there's a new IA collection from an Italian library (Opal Libri Antichi), and that uploads have been done by a wikisourcian, with any possible care about metadata, so that Tpt IA-Commons uploader can be easily used.

Most items have been uploaded as high-resolution TIFF zips, so that a better resolution djvu can be rather simply obtained when needed.
Items are so far mainly ancient Italian books, but there are too many French and Latin books.

In days/hours the goal of first 1000 uploads will be met.
