But when it comes to additional information about the individual coins, I haven't found a good way to organize it. Originally I just tried to remember what I read, after all, it was all interesting, but there comes a point where I could no longer remember what I read. Later I started to take notes in text files, one file per country. This is where I dropped interesting things I have heard or read, related web sites, book titles I read with a short description or sometimes notes I took from each book. But at this point it is a disaster, organized by country. The reason why I don't add notes to the individual coins is because what I read often relates to a particular country, era, etc. I am curious, how do you keep your notes organized, what works for you, what have you tried that didn't seem to work out?
