Bookmarklets with Pop-up Search box

These are closely based on the example from the Stevens Institution http://www.slideshare.net/val_forrestal/metr-obookmarklet-preso To use them, simply drag these links to your Browser's Bookmarks Toolbar to install, and then while viewing any wikipedia page, simply click on that link to launch a search for that page's main topic.

Example 1 - Search my local library catalogue from a wikipedia page

Search GVPL Catalogue for Wikipedia Topic

Example 2 - Search Worldcat from a wikipedia page

Search Worldcat for Wikipedia Topic

Greasemonkey (and/or wikipedia server-side script) to annotate the page itself with links to resources/books

This is what I think is a real winner. Whether through an approach like Folksemantic's overlay or one that actually writes the results into the actual wikipedia page, this result would list actual book titles (could be queried from anyplace, in theory) based on the keyword title. The issue is needing services that actually return results, not just a link to the seach query, and then writing the javascript to format that data and embed it. I am looking at the WorldCat search widget and other existing greasemonkey scripts, but if you know of something that already inserts a block of results in a wikipedia page, as well as book search services that return results and a way to format them, please let me know. I will keep working on it in the meantime.
