SEARCH and BROWSE ETDs
There are at least two search engines that specifically search and browse the complete NDLTD Union Catalog:
This dynamic search and discovery platform driven by Chamo Discovery allows you to sort by relevance, title, and date. In the current implementation, faceted searches are available by language, continent, country, date, format, and source institution. Additional facets, such as subjects or departments, may be added if desired.
This comprehensive scientific research engine from Elsevier provides an advanced search that can narrow results to theses and dissertations as well as provide access to related scholarly resources. To search the NDLTD Union Catalog, use Scirus Advanced, under "Content Sources/Preferred Web sources" click on "List more sources", and check "NDLTD".
Note: Elsevier is planning to discontinue the Scirus service by the end of March 2014.
