The now completed 100 volumes ofGeologiska Föreningens i Stockholm Förhandlingar (GFF)and its history are briefly reviewed. The initiative to start this national society journal stemmed from A.E. Nordenskiöld in 1871. The publication programme has developed from having been essentially author- and member-oriented to more subject-oriented. Swedish was the all-dominant language in the beginning, German and English were frequently used during the first half of this century, and English is now the official language of the journal.GFFhas had 15 editors, two of whom “persisted” for some 20 years. Observations are made on the development of the contents, rate of publication, publication volume, typographical layout, abstract block, cover, instructions to authors, advertisements, financing, and subscription rates
