Thanks Lee and Michael! Very helpful comments! I was keeping track of my custom TMG Source Types in word docs. I also included the Full Footnote, Short Footnote, and Bibliography sentence templates noted along with sample output from sentence previews on the Output form tab of Source Definitions, as well as notes for Source Type Reminders. I reviewed Terry's, Lee's, and Michael's source element tables and copied the Source elements and groups (two columns) into an Excel spreadsheet. I compared the elements to TMG's default (out of the box list) which can be viewed in TMG Help, Search, using "source elements" (yes, with quotes) and in the topic Source Element Groups. This gave me the default source elements and groups. Then, in TMG menu Tools, Source Elements, viewed the resulting list of source elements and compared to the default list. Thus, the custom elements I had added over a period of time were obvious. By selecting a custom element and clicking Edit, the Source Group is shown. Then, I added my custom elements to the new list I made in excel and included an asterisk following the element name for custom elements only. Now, I have a custom list in spreadsheet format for all default and custom source elements. The spreadsheet can be sorted alphabetically on the source element or source group columns as needed for different "ways" to view... or saved as two separate tables. The spreadsheet table is fairly simple, as follows, showing just a couple entries: GROUP............................ELEMENT Author.............................Agency Record Type....................County * Second Location............. State * Finally, it was fairly easy to add a list of source elements and groups to the word docs I already had for tracking custom TMG Source Types. I added the elements and groups used for each specific custom Source Type to make it easier to edit or copy them for other custom source types in the future. Thanks, Tom
