Thanks for reaching out!
Tom with Wiley
I discussed your case with Tom, and we identified that the book does have a companion site which directs to alphaarchitect.com. I am sorry for any inconvenience, but you'll need to contact that company to inquire about the materials. You can find a contact form here: https://alphaarchitect.com/contact/
They should be able to assist you in locating those materials if you provide the name of the resource and the ISBN of your book.
Please let us know if you have any questions. Have a great day!
