I can't say how this product has helped create organization for my negatives and extra photos. I love the sheets in the back for storing negatives, so what I ended up doing was filling the entire book full of negatives so I could throw away those old envelopes that use to hold the negatives. I used a label sticker to write the date and topic of the negatives. I currently own 3 of these and they are completely full. This small size fits on my bookshelf better than the 3up size.
