I’d recommend the book, “Stuff: Compulsive Hoarding and the Meaning of Things” by Randy Frost and “What Every Professional Organizer Needs to Know about Hoarding” by Judith Kolberg. Both are excellent text written by experts in the field.

We are still in the learning stages of understanding and classifying hoarding. It is a very complex and fascinating issue that affects people worldwide regardless socioeconomic conditions. As a professional organizers, my colleagues and I have seen first hand what hoarding is truly about, but we have so much left to learn!

Thank you for sharing some valuable information. This infograph is actually very educational also:
