(...) Digitalitzations come from google books, but they were free access (it doesn't mean no cost) only with USA IPs. In addition, they were hard to access because metada was wrong and different books were displayed in a same file. We didn't find 3 books, but we are seeking them in libraries. Almost all books are poetry book, but some editions include theatre and novel. We know that our scope is too ambicious, but we expect that almost all editings will be in no more than ten books.

Have you tried HathiTrust ? [1] [2]

In short, some libraries that have allowed Google to digitize their books realized the big mess that was done on metadata an scan quality and managed to create a kinda of fork with very powerful search capabilities plus a feedback space that you can request to re-digitize some books.

They restrict the download in the very same way as Google Book Search does regarding year of publication and USA IP address. But using a third part download manager [3] you can get scans in JPEG/PNG up to "400%" resolution, what makes the OCR quality and DjVu generation very improved.

I personally download from them using a Virtual Machine with a Hotspot Shield [4] installation, that provides me a IP from USA.

If you or someone else needs, I will be glad to generate/regenerate DjVus for those titles (ATM I've generated few dozens to pt.wikisource, but I'm uploading those very slowly most to personal laziness xD )
