This volume contains a wealth of information on the word accentual (metrical, stress) phenomena that we encounter in natural languages. Two types of information will be supplied: language profiles in 'tabular form' and survey articles. Of the total of 10 chapters in Part I, 3 are general in nature, while the other 7 describe and analyze word accentual systems in all continents. The volume's point of departure is a database called StressTyp. StressTyp developed into a database on word prosodic systems of the languages of the world. The over 500 languages, representing a wide geographical distribution, taken from the StressTyp database will be represented in this volume. For all these languages, information regarding identity, sources and stress location(s) will be included, accompanied by some examples in nearly all cases. These language data packages will be organized by language family. This information constitutes Part II of the volume.
