File quality should be stated

[Gon Paran]

I believe that the quality of the file is very important and I'd like to suggest that people who post books would state what kind is it. is it a scanned book, is it convetrted into editable text with an OCR software or is it an original pdf file.
I hope it is agreeable.

Quality is subjective and not easy to prove prior to downloading. Would be great if there was some way to preview file before downloading.
