<p>Catherine & All<br>
</p>
<p>First, abandon 1-dimensional barcodes. These are i) error
prone. Human eye cannot see if the starting or stopping bar is
missing. It is too easy to print such labels which look good but
have been cropped from their ends. ii) 1-dimensional barcodes
plenty of space on a herbarium sheet or similar. They unusable
for small insect labels. iii) When digitizing the collection,
1-dimensional barcodes (such as code39 etc) are hard to detect by
machine from the images. <br>
</p>
<p>Only use 2-dimensional QR codes, or similar. All the problems
which listed above can be avoided that way. Human eye can
immediately see if the QR label has technical problems. QR codes
are smaller and prettier. QR code can instantly be recognized and
read by machine from a 135 MB TIFF image.</p>
<p>What you encode in the QR code is your choice. UUID is fine but
needs a resolver. A web address, as recommended by the European
CETAF organization may be better. I let GBIF, DiSSCo and iDigBio
to comment about that.</p>

<div class="gmail_default" style="font-family:trebuchet
ms,sans-serif">I have never used barcodes for digitizing but
will be submitting a proposal that should include them, so I'm
looking for some advice. We will be barcoding a diverse
collection of vertebrates, shells, and plants, and I want to
use these barcodes to assign true UUIDs (example: <a
href="https://www.uuidgenerator.net/" moz-do-not-send="true"
class="moz-txt-link-freetext">https://www.uuidgenerator.net/</a>)
and not a sequential set of letters and numbers determined by
humans. Can you recommend a barcode printer (and compatible
adhesive paper) that 1) can serve in multiple storage settings
(both dry and alcohol) and 2) can encode UUIDs? We would like
to print them in-house instead of sending off for someone else
to print them for us as we will need to print duplicates when
we find different preparations of the same specimen (e.g.,
skeleton, skin, soft tissues) in different parts of our
collection.</div>
