Disclaimer about Amazon links on Illacertus:

I participate in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn commissions by linking to Amazon.

In other words, this means that whenever you buy a book on Amazon from a link provided on here, I get a small percentage of its price.

That helps support my work by offsetting a fraction of what it takes to maintain the homepage and the illacertus YouTube channel. Your contribution is very much appreciated.
