The Visual Dictionary es un excelente recurso para buscar imágenes y vídeos con fines educativos.
"Have you ever wondered what the various parts of a guitar are called? Perhaps you need a refresher on the various types of dresses? The Visual Dictionary website covers both topics in copious detail, along with offering up information on transportation, biology, and the human body. Essentially, the site offers annotated images that identify each part of a given item, such as an automobile or a musical instrument. Visitors can search the site by using the embedded search engine or they can look over a list of topics. The coverage is quite broad, as users will find everything from the detailed anatomy of a turtle to an exploration of a car's engine."
