Yes... most certainly, everything is relative, isn't it?

Surprisingly, their combined physical space is little more than that required by a single bound volume of "The American Practical Navigator" by Nathaniel Bowdidtch. Yet they host about 2,000 feature length movies, several thousand miscellaneous videos, probably 1,000 eReader books in various formats, a little over 500 audio books, all of my programming technical manuals, etc. Even more importantly, I have parts lists and rebuild manuals (also PDF) for just about every piece of hardware and/or electronics on the boat.

Most of these, you understand are for reference as needed, not for reading, per se. Suffice to say that I'd sooner "have it and not need it", than be half way 'round the world when "I need it but don't have it", and tackle the rebuild my engine, etc. I suppose it's a bit like the old days of your youth, when you're parents bought you the complete Encyclopedia Britannica. They purchased it for your "reference"... not for "light reading".

Most assuredly, if the Apollo Mission COULD have taken more along so efficiently, they WOULD have!
