Eh?

What databooks I have on hand besides this seem to concentrate on chips
rather than discrete stuff for the most part...

And this is a perfect example of why it's still nice to have all those
paper databooks on hand when you can get all those .pdf datasheets on the
'net...

I know of NTE,  and when they first came out they didn't seem to work as
well as ECG did for the same numbers.  Nowadays it seems like they've
pretty much taken over.  And I have an SK book around also,  somewhere, 
though it's probably not all that current either (neither are most of the
parts I'm looking up...   :-).  Never heard of VIS.
