Bingo. Don’t read to “memorize”; read so you know where to find the relevant information later. If that information is frequently relevant, you’ll eventually learn it and won’t have to look it up as much.

Great example: when was the last time you had to look up how to append an item to a list in your favorite/most used programming environment? You probably don’t remember when that was, because you use it so often, but, there was a time when you did have to look it up (when you were first learning).
