VTLS provides a dynamic search and discovery platform (driven by Chamo Discovery), which 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.
