The Avalon project website, in association with Yale University, offers the visitor an interesting way to view and compare documents. The website's strongest, and most interesting feature lies in its design, which is the ability to view documents side by side for comparison. Utilizing frames, the visitor is able to compare many historical documents which serves to more easily view similarities and differences. This feature is an interesting, and helpful way to view these early documents.
