The journal began in 1976, and in 1988 introduced a new format and a broader editorial board. Since then we have been able to combine good standards of published papers with moderate waiting time. Presently, the average publication delay is about seven months. A volume is published each year divided into two issues. For information on prices click the "How to subscribe" button shown above.
