This was an issue I had to deal with when my sister lost her battle with Colon Cancer in 2001. She had over 2,500 quilt books & a 7 bedrrom house & 2 storage facilities filled with fabric & notions. She also lived 300 miles from me & I was still working as a teacher. As I had only been quilting a few years at that time, I did not know the value of some of the quilt books. If you have a quilt book selection, I suggest getting them listed & include the retail price as well as what you paid for them. Indicate those that are collector's sought after titles. This will help anyone who is given the task of selling them or even claiming them as a charitable tax deduction.
