STMA-Z is a database of mathematical and general statistics for experts from science, research and industry, as well as for teachers and students. It is the successor of the Statistical Theory and Methods Abstracts Database (STMA) that was published by the International Statistical Institute (ISI). It attempts complete coverage of worldwide literature in the fields of statistics, probability theory, and financial mathematics.
The structure and search functions are the same as in zbMATH, which also covers mathematical statistics and is published in international cooperation.

STMA-Z is published by FIZ Karlsruhe in cooperation with ISI. It comprises about 445,000 records (2010), with an annual growth rate of about 20,000.
