A computer search would have given me a list of pertinent cases, but without that I had to read everything. That is harder by far, but you end up learning a lot more. I was forced to remember cases because making copies of everything was too expensive. Keeping cases in your head is good, too, because cases are like puzzle pieces floating around in your mind, and sometimes, in moments of creativity, they fall into place and form a picture. If they were words on a screen that you could pull up anytime you wished, that phenomenon wouldn't happen as easily.
