This one corner alone took about a week to clean up. Once it was empty a new book case was put in which led to phase 2. Over Thanksgiving break the books were pulled off the shelves, scanned onto librarything, then put all 628 books in my room to be sorted and shelved. Labelled the books while scanning so we know which ones were scanned thanks to a friends recommendation. I also labelled the shelves by category so we all know what goes where. It's a good check for me when I'm cleaning up. Even Melania at 18 months has a bottom row of books for herself to go through.
