I've been basically keeping two log books. One was the traditional pen
and paper logbook that my CFI/CFII signed. The other is electronic.
Good thing I kept the electronic one as it made figuring out the
dozen or two dozen questions about the hours the FAA has when I applied
for my IFR.

From previous threads, the electronic log book is apparently completely
legal as the FAR's don't specify how you keep the log.

So my question....for logging IFR approaches with a safety pilot, you
have to put down the date, flight time, location, aircraft number and
type, type of approach, and the name and certificate number of the
safety pilot. I'm assuming an electronic log book is sufficient but is
there any reason I should log these with pen and paper? I'd assume
if it is better to log it with pen and paper then the same would
go for currency with respect to aircraft type, landings, night landings,
and everything else.
