Hi Herb,
Welcome to the 'flexibility' of XML in Word 2007

(i.e. you can change the label lists if you wanted to <g>
I started looking at some of the other companies and noted that those, such as C-Line Products showed both a number and a name
description in the Label Options 'Product Number' field, so I searched a bit
All of the out-of-the-box label definitions are stored in .XML files in the
\Program Files\Microsoft Office\Office 12\PageSize folder.
It looks like each of the label providers created their own XML documents to list their labels, probably using something as simple
as an Infopath or Word form to create an XML file of label definitions.
Avery U.S. has a MS Partner ID of 81, so their definitions are in
PGMN081.xml PGLbl081.xml
Avery A4/A5 has a MS Partner ID of 48, their definitions are in
PGMN048.xml (papers) PGLBL048.xml (label sheets)
C-Line is Partner ID 97,
PGMN097.xml PGLbl081.xml
The Partner ID/Category Index and layout groupings by label type are in
PG_Index.xml
When you create a custom label it's placed in the User's appdata folder in a file named pg_custom.xml
Each label name that appears in the list is stored in a field of
<locName locale="all">Number & Name of Label</locName>
(locale can vary)
It appears that some vendors chose to list just label numbers, some names, and some a combination. Whether they didn't understand,
or thought there would be two fields, etc, is strictly guesswork

but it's possible to modify a label set.
================
Mailings tab, Labels, click on the Label icon. Set Label vendors: to Avery
US Letter.
You'll find it close to the end. Note that things are sorted in alphabetical
order, not numerical order. Hence, you'll go through everything starting
with 1 before getting to the 2s, etc. So, 8662 comes long *after* 11101. To
get there quickly, drag the scrollbox to the bottom (8987), then go up a
couple of screens to find 8662.
