Chips load from the side on the 80-pocket books, Barry
If you use 3-ring binders and plastic pages for chips, I recommend using the 30-pocket pages which have the same 1 1/2" pockets as in the books I mentioned. They do top-load, but when new, they hold the chip pretty tightly. I find all these plastic items last about 1 1/2 to 2 years, after which they must be replaced, either due to the plastic stretching or tearing, or the holes tearing out. Wish there were something better, but haven't found anything.
I find that the COWAN brand has the best durability in the 3-ring binder pages.
