I now have 5 logbooks, the oldest was
very tatty when I went for my last job interview - one of the pilots interviewing me picked it up, sniffed it and exclaimed "Ahh, experience" - I got the job.
To be honest though, if you are going into aviation as a career I would forget paper logbooks and go for something like Skylog pro, You can summarise your old log books into it, it then does not run out, also, when you apply for jobs you will find every company you apply to wants your hours in a different way, easy to do with an electronic log book, but takes
ages working it all out from paper ones!
