Hello, Elizabeth, A regional database that takes advantage of EAD tags in searching and browsing is the Northwest Digital Archives: http://nwda-db.wsulibs.wsu.edu/nwda%2Dsearch/ In addition to the browsing options, click on Advanced Search. The Library of Congress browse options depend on tags: http://lcweb2.loc.gov/faid/ And the University of Washington Libraries Special Collections Division provides quite a few options for searching and browsing based on tagged information: http://www.lib.washington.edu/specialcoll/findaids/ Thanks.

Yesterday I got this question from a student: "We're doing all this encoding in part so that search engines can search these documents better and understand when Washington is a city or a person's name. What kinds of search engines are we talking about? Not Yahoo or Google. Can you give us a demo of one of these search engines?" I know that the Women Travel Writers Project set up tag-based searches in DynaWeb, but they've gone away. Does anyone know of others? Elizabeth H.
