The scanned version directly scans the original page content and then stores it. Support add, delete and check functions, and support batch scanning and one-by-one scanning mode.

Photocopy is the original, and the whole book is completely copied according to the original book of the original publishing house, and then published in the name of the original publishing house, and must be marked "Photocopy". Photocopying does not support the function of adding, deleting and checking.
