Index Diachronica is a list of sound changes from many, many, many, many different languages. However, it is large, and it doesn't use Unicode, making it hard to search for specific sounds. Therefore, I made a Unicode PDF, and also an HTML version (since I know at least Apple's Preview has trouble searching for certain Unicode characters (like ʷ) even if a document is in Unicode), and also made a search tool. (Note that I did not make the Index, I only converted it to HTML and made the search tool.)

(There still may be bugs to work out.)
