Editorial: Writing in Grana

It has been necessary to re-organize the production of GRANA. The following changes in publishing policy are the most important. 1. GRANA will continue to accept papers in its traditional field of interest, but in future, papers in the applied branches of Palynology, such as pollen-analytical studies, will also be published, as well as papers on other micropalae-ontological fields, in which the methods correspond to those used in palynological research (dinoflagellates, chitinozoa, diatoms, etc.). Only material that is obviously of international interest will be accepted. 2. From now on, there will be restrictions as to the length of a paper. Two types of contributions will be acceptable: Articles, containing 16 printed pages at the most, including the figures, and Notes, covering four printed pages at the most. The Notes will be given priority over the Articles, and will be included in the journal as soon as they have been scrutinized by a referee and prepared for publication by the editorial staff. Thus, the writing of Notes will be the quick way to secure publication in GRANA. The rest of this article gives the technical specifications of GRANA and also some instructions for authors.
