I typically set things up as projects. When I'm working on the projects, almost daily over to make sure I remember things correctly. I also make additional notes when I'm going through the project so I can have everything in one place. A lot of the time I may work on one thing, then it's a couple of weeks and I need to get back into it.
At some point, everything will get written into a digital scope of work document or deliverable. At that point, most things become superfluous and I don't look back into notes.
Every once in a while I'll want to remember a name or a book and I like being able to have those at the tip of my fingers. Those things are typically in a different notebook.
