Some people in the archiving / 'data hoarding' community feel it's simpler to just back up everything. This attitude is particularly prevalent in the communities that deal with data other people have already digitised. If you're paying $100 per book for someone to visit a major library, get the book out, scan it, check the OCR? Then you'd probably be selective, to get the most out of a limited budget. But if you're grabbing epubs and pdfs, and a book only needs $0.002 of space on a hard drive somewhere? Grabbing the useless 41% is probably cheaper and easier than exercising editorial control.
