To store an infinite amount of data on a toothpick, assign a numerical value to each letter of the alphabet (00 for 'a', 01 for 'b' and so on) - you could even use their ASCII codes. Next string all the letters making up the encyclopedia together to form a very large number. You'll end up with something like this 0419041713081924...
Next turn this number into a fraction by pre-pending a 0. to it and make a mark on the toothpick at exactly this point of its length (where 0 is the start of the toothpick and 1 is its end). This mark contains all the information of the encoded encyclopedia in its position.
