DVA Special Markets. (From their website) "We are DVA, the largest distributor of authentic studio released special interest DVD and VHS at deep discount prices. We would like to invite you to visit our website with a special 10% discount code for educators. There you will find hundreds of great educational videos from studios like PBS, A&E, Discovery Channel, History Channel and National Geographic." The DVA material is obviously secular in content, so buyer beware; however, some are from the History Channel and PBS which were quite good at truly "cheap" prices!

Webster's 1828 Dictionary. Noah Webster could best be described as an America's first curriculum writer. Concerned with the quality of books in Amercian schools (a hodge podge of used English books), He revolutionized American educational curriculum in the 1780's by producing the Blue Back Speller which taught children how to read for over 100 years. He later wrote the first American dictionary which standardized American spellings and recognized uniquely American words (such as squash). His strong Christian character and firm grasp of the principles of government shine through in his definitions. Here's another site for Webster's dictionary (since these free sites do change from time to time).
