2wheelwander, that's a pretty nifty comprehensive book. Looks like it holds all the data you would need etc. Ten years ago I would have gotten something like that. As I got pulled into the electronic digital world (kicking and screaming) I did eventually realize the value of having something in the cloud, or at least on several hard drives somewhere, instead of on one physical book that could burn in a fire, and is only accessible wherever it physically is. The added benefit of being able to pull that phone from my pocket and pull up any information about my guns, serial numbers, pics, range data.. anything, was pretty appealing. Even more so being able to ADD to that digital file from that phone or laptop anywhere there was cell service or WiFi. If I really need a hard paper copy I just print it out. I suppose you could put those printouts in a notebook and still have a physical file you can hold and page through, but personally I don't bother with that. Anyway, I fully understand that approach is not for everybody. For me the ability to access and add to my gun file from anywhere was pretty appealing and that's what I now do. In fact, not just guns, but all data or info about everything from my car maintenance to health information is now digital, in an iPhone Note or WORD file, in the cloud (DropBox etc) so it's accessible from my phone or laptop from anywhere.
