Where can you buy cel books

you're welcome ^^
the best solution would be the framing, but specific framing (air coming inside, window not too close from the cel, and anti U.V) but more expensive.

Even with the most expensive of framing light is not good for cels it hastens their deterioration.

However the box method is what Disney uses, all Microchamber boxes and matting with only three to four cels per box. As stated before for a private collector with a large collection this is not reasonable lol.

So for a larger collections the Itoya Binders are the best I use the large blanket hangers to hang them in my closet so there is no pressure put on the paint.
