I cannot believe how many gadgets are invented to just hold a book! I just found another one. It is called the “Easy Book Clip”. As always, I am concerned about the gadget damaging the pages. I have not tested this product, but it seems like it might do some harm to the pages. In any case, it seems not easy to turn them. If you have any experience with this product, please let me know!
