	In O'Reilly's book Mind Performance Hacks, the author covers a system for memorizing information called the Dominic System. This system maps 10 numbers to 10 letters. That makes each two-digit number into a two-letter combination. By associating memorable people, actions, and places with those two letter combinations, you can turn numbers into people, places, actions, and things, and use those to create absurd fantastic stories that help you remember the numbers.

			==Twain System==

			In <u>Taming the Bicycle and Other Essays, Stories, and Sketches</u>, there is an essay called "How to Make History Dates Stick (written circa 1899, published 1914)".

			Ironically, you've probably already forgotten the two years given in the title of the piece.

			The article is several pages and includes hand-drawn sketches by Twain to demonstrate his mnemonics technique for teaching his children the names and number of years of each of the rulers of England.
