If there is more than a .000000000001% chance you will ever in your life present your logbook at a job interview then get an electronic logbook. If this is you then start early and start NOW.
I've attended a lot of job interviews (and been hired a lot) for quite a few different kinds of flying, from utility to airline and a lot of stuff in between. A few places haven't bothered to review my logbooks, but most have.
Recently I interviewed with an operator who did look through my logs. My logbooks include all my medicals glued in order in the back, as well as my government cardings, etc. Business cards, some photographs, and other documentation is there. The logs are in black ink and blue. There are a few things printed and glued in there. Some of the logbooks are falling apart; the spines are glued together with reinforcing tape or leather holding them in one piece.
The operator discussed my logbook over lunch. They'd recently had an applicant who talked a great story, but when it came to certain items in their past, they didn't want to talk about it. Their logs weren't nearly as complete, and when it came to some of the things they claimed to have done, they were found to be false. Some of the background wasn't as easily traceable as say, flying for an airline. Some of it involved operations in places and with organizations that aren't nearly as forthcoming or open, but this particular operator had just such a background, and a fairly good bull**** detector, as well as some fairly extensive connections with that community. It turned out that the other person was lying, on multiple counts. The extent of the lying was actually surprising.
In my case, the operator noted that they had no problem verifying my experience; it was all there, as well as all the means to check it out. They made copies of certain items. They didn't care about blue ink or black ink. Most of the log entries contained a lot of detail, from winds to call signs to trip numbers to specific fire numbers to other details that clearly authenticated the record. It made them easy to check. The operator was quite pleased with what was found.
I've never shown an operator or employer my electronic records. They're not complete anyway; they're mainly a way to keep track of things when I'm in the field for an extended time, before I can transfer them to a paper logbook at home.
The paper logs remain in a fire resistant safe.
I don't do totals in pencil. From time to time I'll find an error. It's a very simple thing to address. Just make a new line entry, as though it's a new flight. Put the current date. Make the corrections in the appropriate column (plus or minus), and in the comments section, note what's being corrected and for what page number or date in the logbook. Then at the bottom of the page, the totals will be correct, and it's hardly noticeable. It blends in and doesn't scream "mistake!" in big letters. It's far better than erasing and correcting a total. Your logbook shouldn't be altered; if you make mistakes, move on, and make an entry later when the mistake is found. It's a very simple thing.
You people with just paper logbooks...they are going to end up in a land fill. Your grand kids or kids are never going to go through them and care 1 billionth as much as you do. My point is the logbook is a record. It's sentimental to you alone...but at the end of the day it's a record.
I know a lot of people who treasure their parents (or grandparent's) logbook. It's often a piece of historical heirloom that marks an important part of that ancestor's life. One's grandfather may have served as a pilot in WWII; that war is long over and most likely that person is long dead, but the logbook may pass down through generations just the same. Perhaps to you it's not a big thing.
My logbooks are a journal of my life. I've been flying all my teenage and adult life, and it's been a very varied and divergent career. My logs will never be best sellers or museum pieces, and I don't care if my children keep them or burn them. It really doesn't matter. My logs are accurate meticulous records of my life, complete with souvineers, pictures, and details that mark most of my time on earth. That's enough for me. No electronic book can take that place.
My logbooks have saved me from the FAA twice, and from court involvement more than once. They've served as reference records for the winds on a given day when spraing crops, helping me avoid dealing with an expensive drift claim. My logs showed endorsements and instruction given that kept me out of a court room when a former student crashed and destroyed an airplane. My logbooks convinced the FAA not to proceed with certificate action when I was able to show that my records of a particular flight (and the duty and rest times associated with it) were more more comprehensive and complete than the company records. Instead, scrutiny was thrown on the company, which didn't keep nearly as good records.
My logs have satisfied employers, investigators, and friends. They've been pawed through by the FAA, by airlines, charter operators, ag operators, government agencies, and others. They've been vetted and checked. They're my scrapbooks. I don't care if they make it through generations to come, but I do care if they work for me, and they do.
Electronic logs are okay, but they'll never take the place of my paper logs.
I was once looking at purchasing a Smith Mini-Plane. I was talking with an old hand at the time, and commented that employes reading the logbook probably wouldn't know what it was. "Why don't you snap a picture and put it in the logbook?" He said. It would answer their question, and it would be a conversation piece. Handy in an interview. I've got a few pictures here and there, a few momentos. Business cards. Memorabilia. Nothing elaborate. They're not photo albums, nor are they destined to be anything but my own logbooks. My jump logs are the same way. Perhaps important to nobody but me, but then they don't have to be. They've proven invaluable in seeking employment, and they've satisfied the FAA, designated examiners, the curious, and the dubious. That's more than enough for me.
Electronics are dandy, but won't ever take the place of my paper logs. I started a new one a few months ago, and like the last, it will probably take over ten years to fill. Ten years from now I probably won't be any closer to finishing moving everything to an electronic book, but will likely have made some headway on the current mint-green paper one.
