Designed by Lawrence K. Lo, this Web site is meant to serve as "an introduction to writing systems, which hopefully will tantalize the reader into searching for more information." Lo offers visitors a brief overview of several topics related to linguistics (both modern and historical) in sections devoted to writing systems, sounds and phonetics, and historical linguistics. In the writing systems, Lo offers a brief overview of writing systems over the millennia and then concludes with several categories of languages around types, families, geographical regions, and an alphabetical listing. From these categories, users can obtain information about any number of languages, including Aztec, Sumerian, Cherokee, Old Persian, and literally dozens of others. The section of phonetics contains a summary of how different tones can be utilized to create a host of varied sounds and meanings. The site concludes with a brief discussion of why languages evolve over time and a bibliography of helpful linguistic resources used to create the site.
