True enough. Depends on the Mfg, and ADI (among others) is pretty good 
about keeping old stuff online. Don't you hate it when a company doesn't 
just discontinue a part, but almost disavows it ever existed? If there's 
a reason for that beyond plain cheap/lazy I can't think of it.

Nice. Looks like a _lot_ of work.

I guess the ideal case would be "The Ultracomplete Maxi-Megalon Library 
of Every Datasheet Ever Conceived" (to borrow from Douglas Adams, RIP). 
This would have the following characteristics:

* Free
* Wide Bandwidth
* Contains _everything_
* Google (and all other web indexes) would list it first in their results.
* All PDF (or high-res scans of old printed sheets)
* Sort by function, Mfg, part number, package, dates of production, etc
* Includes cross-references
* (reaching) Includes private/custom/house number cross refs.

I suppose that a few sites out there come close to this, but I've found 
that they all have holes in 'em and I have to be prepared to try a few 
different ones to ensure success. That's why the actual Mfg is always my 
first stop.
