I use the binder to organize and store book reviews and discussion guides for my book club. Keeping magazine and newspaper clipping reviews mean that I'm alway ready to share future book selections with the club. They think I'm so organized but it's a simple matter of keeping the notebook handy and updated.
We use these binders in large legal cases. They are sturdy but not heavy. They hold up well and store well. My only wish is that the 1.5" and larger have a bit more reinforcement in the front and back covers as the weight of the contents can bend them. Otherwise no one has anything better going especially as light weight.
