I am looking for information about bar codes and bar code readers.
If you have knowledge in this area, I would like to contact you.
If you have pointers to books &/or articles &/or experts, please let me know.

The problem: connect a bar code reader to a micro computer. The term "micro
computer" is intentionally vague, as I have several in mind.  Assume each has
a TTL input port.

Related problems: where find a bar code wand? 
		  how to build a bar code wand?
		  can an HP bar code wand be attached to any old micro?
		  where do you locate an HP wand (and specs)???

More Related problems: software!
	I've found articles in BYTE that describe algorithms for reading 
bar codes.  They appear to be specific to the PaperBYTE (tm) system that
was used a few years back.  Does anyone still use this format?  
What about the bar codes on packages (UPC), aren't they a different
format?  What is 5-of-9, and all they others?  Where can I find
definitions of all these formats, and *why are there so many*!?
