My husband kept a lot of old engineering-school Stuff for a while, but I finally persuaded him to dump it.
Engineering is a lot like taxes, in that, by the time the printed materials reach the public, they’re already out of date.
I know how that goes! A couple of semesters ago, shortly before my class went over a section in the textbook, a court handed down a ruling that changed a chunk of the chapter. I have to make sure I keep up with what's going on in the world.
And now I have to step away from the computer again and try to put more things away. Unfortunately, I seem to make an even bigger mess by the time I'm finished!
That's awful! You never know when you might have to design, say, a circuit using 12AX7 dual triodes, so I still have my trusty old 1960 Sylvania vacuum tube guide on the shelf.
