Sometimes once isn't enough. You might be amazed to discover how valuable it is to reread books you've read several years before, especially books you thought were hard. When you reread them and can't figure out why you ever thought they were hard, you'll know you've made progress. And finally, I've learned to make routine searches for new books from my favorite authors, many of whom you'll find listed in this selection. There is tremendous satisfaction to be gained from reading books that authors you find intriguing have used as resources.
Bibliographies alone can lend incredible insight.
For the purposes of simplicity the titles on this page are listed alphabetically by author within each section. These sections are broad-brush categories of my own making and may seem out of sync with your personal logic. I therefore invite you to browse through them all. Of special note is the section on credentials, which addresses common problems encountered by self-educated people. I recommend your public library.
