Years ago I used to print spiral-bind ham radio log books for sale, but I found that only was able to sell a few - even at a very low price. I offered them online and at hamfests.
I have always kept a paper log and was surprised how few other hams did so. Those who kept a log at all wanted to do it by computer. This approach makes a lot of sense and I understand the modern reasons for doing so (fast searching and data-sharing with online systems particularly), but for me the paper log is somehow more satisfying.
Attached is a free page from my logs in both pdf and spreadsheet form. The spreadsheet file is useful if you would like to customize it to have different columns, headings, etc.
