Ellen, I'm new to the National Archives, but I found this information about tagging a document vs. tagging a page:
"There are two ways to add tags:
"Place tags on the left side column to tag the entire record
"Add tags directly to an individual page under the image using "View/Add Contributions” and select the Tag tab."
You can find out more about tagging here:
Thank you for your question, and Laurie, thank you for providing those resources!
If you add a tag to one page in a multi-page document, it applies to that particular page. However, if you or another user conduct a search for that tag, it will return the full record.
If you want a tag to apply to the entire document, we suggest adding it to the left side column on the main description page.
I hope that is helpful. Thank you both for your work as Citizen Archivists!
