The first annual report has been published in 1928 and covered the years 1928-1928. It provides a good overview on the origin and development of Eduard Rübel's private research. Since 1931, the annual reports appear on a yearly basis and contain scientific publications, as well as briefings on the scientific activity of the institute. Over the years, these reports became an important source of information in geobotany.
The release of these reports has stopped in 2003, because scientific results are now mainly published in international, cross-referenced journals, which can furthermore be accessed on the Internet. Today, the Rübel Foundation supports the publication of the international journal Perspectives in Plant Ecology, Evolution and Systematics.
