I still have all the supplies and equipment to make the spiral-bound logbooks. I shut that business down as I found that only was able to sell a few - even at a very low price. I tried offering 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 seemed to want 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.
