Good to know this, thanks. The fact remains that almost no one but a
few people in Intermec and a handful of biologists have ever heard of
code49.

I'm not convinced that code128 won't hold what we need, since all we
need is a unique alphanumeric code. I'm still checking on that. And I
will not put symbology face up, nor will any entomologist I know
accept that.

Tell me more. Is this getting close to optical character recognition,
where we won't need a symbology at all? Then I might accept a face-up
label, that has all the locality data and a unique number.

Any ideas on who might maintain a registry of barcode labels being used?
