Since 1998, the Casia Corporation Holland have been working on The Definitive TLA Wörterbuch to help people find their way in the ever growing intellectual chaos caused by the late-twentieth century tendency to use as many acronyms in the daily communication as possible. Especially acronyms with a length of three letters have been and continue to be immensly popular, not only in Information and Communication Technology circles, but also among people in more mundane fields of labour; a tendency that has mushroomed with the advent of mobile communication and the combined growing popularity of Short Message Services.

At present, there are 6281 (3972 distinct) TLA's in the database.
