I've gotten three jobs by taking my electronic log book to the interviews. Fedex do a great job of printing binding it for you, all for less than $15 dollars. They make it look really sharp and the interviewers commented as such.
I have also scanned all my sign off's and endorsements so and placed them at the back of the logbook. I have full paper logbooks that mirrors my electronic one in case they want to see the originals of anything (which so far they have not).
Electronic log book is great for ensuring no errors in the paper one, a good balancing tool for checking correctness of your paper one.
