The IOBC-WPRS Bulletins are a well established series of relatively fast issued working papers in a systematic format.
This publication is an important support to the WPRS expert groups: Bulletins are proceedings of Working and Study Group meetings and Commission activities.
The number of volumes varies each year (7-15 volumes).
IOBC-WPRS ePublications can be downloaded as PDFs from the Online Shop.
IOBC-WPRS Bulletins older than 2 years are open to public and free of charges.
