does anyone really need an elfrink?

Seriously, an Elfrink manual used to be one of the staples of 356 ownership.  It was an early publication on the basics of 356 ownership and repair.  Emphasis on the basics.  I used to have one, but sold it off with the last car.
I've worked probably harder than most on collecting excellent  condition original PORSCHE factory Parts Manuals and Workshop Manuals- amongst other publications.  So, I was asking myself, do I, or really does anyone really need an Elfrink book anymore?  We have the 356 Registry website with lots of friendly help.  There are versions of the parts books on line, and all of it in greater detail than the old standard Elfrink.  
I've noticed the prices of these old books are now below $20, so honestly, cost is not an issue, but why buy one?  My conclusion is that after decades of 356 ownership, probably I would never look in the book.  However, if a new owner who is not well rehearsed in the little things that can go wrong with a 356, well then maybe, just maybe putting one down in the battery box as a "just in case" protection.  It no longer even deserves a spot in our glove box.
​Sorry Elfrink!
