This series was published fortnightly by the German Administration in Rabaul. Local people were trained as printers and in other areas of the printing industry and the paper was produced using these local tradesmen.

These photocopies of the originals have been bound into 11 volumes, including two supplements to the 1913 issues (Vol.IV): one on the establishment of the botanic gardens at Rabaul by Dr Gerhrmann and the other on types of shell and molluscs by M. Braun. An index appears at the beginning of each volume. The page numbers are sequential from issue number one to the end of the last issue for each year.
