Affiliate Marketing Notice

In Summary:  There may be links to books and other products that take you to an online commerce site, such as (“referral” or “affiliate marketing” links).  These referral links to other companies pay a very small commission on purchases you make to Alan, at no additional cost to you. They go a tiny way towards defraying my costs to keep the website up and running.
