Depending on the domain you're interested, this may or may not be important. I work on old Toyota 4x4's, and frequently refer to old forum posts. The details on a brake job for a 4Runner aren't going to change, ever, so this is fine.
I totally agree with you about how the details on changing or upgrading truck components are not mutable as the example below shows, that parts conversion is compatible from 1196-2002 series cars, you can't say 19xx to 20xx computers, nowhere close.
