From NSDLWiki
This help page will show you how to add a wiki page and its associated resources to the NSDL. This feature is only available to authorized library builders. If you would like to discuss becoming an authorized user, please send us a request with your information.
It's best if you open a second tab or window so you can read these instructions and write the post at the same time. (there's a small bug that makes you sign in again for new windows and tabs --Elly 12:02, 26 March 2008 (EDT))
To get started, please see the accounts help to sign in or register and then navigate to the wiki page you want to publish to the NSDL Data Repository or to create a new page see the Help pages).
Look for the NSDL tab along the top of the article and click on it. (Click on the image for a larger version)

You can then also add or edit existing metadata for the referenced resources linked in the wiki article. (Click for larger image)
NOTE: The search indexing process takes up to 24 hours, so you will not see your resources in the search results right away.
