So, some students can online read the required for their work, and often very expensive books from the first to the last page and browse.

That the books are all in a uniform quality to the available software is ensured by callas.

So, all hidden problems are detected and corrected during the conversion. These functions allow PaperC quasi automatic recording new books and make sure that the virtual range grows rapidly.
