Editors’ preface – a new start

Another stage in the evolution of both Contributions to Tertiary and Quaternary Geology and Tertiary Research has now been achieved – their amalgamation into this, the new journal, Cainozoic Research. Tertiary Research (ISSN 0308-9649) will cease publication with volume 22, Contributions to Tertiary and Quaternary Geology (ISSN 0165-280X) with volume 37, both for the year 2000. Contributions first came out in 1964, as the journal of the Dutch Werkgroep voor Tertiaire en Kwartaire Geologic (WTKG) under the name Mededelingen van de Werkgroep voor Tertiaire en Kwartaire Geologic. It appeared twice a year and was produced from stencils and printed on a single side of the paper. Starting in 1972 (volume 9), double-sided printing was introduced, as were photographs. Volume 15, part 1 (1978) was the first printed edition (as opposed to stencilled) and Dr W. Backhuys, in various capacities, took on the publishing from volume 15(2) to the present. Initially, the journal was published by ‘Dr W. Backhuys, Uitgever, Rotterdam’ and from 1982 (volume 19) by the publishing house E.J. Brill, Leiden. In 1990, prompted by reorganisation in publishing house Brill, the journal’s name changed to Contributions to Tertiary and Quaternary Geology and publication was taken up by Universal Book Services/Dr W. Backhuys, Oegstgeest. From that moment on. Contributions primarily was an Englishlanguage publication, and attracted papers of a more international nature, although the focus still was on Cainozoic palaeontology and stratigraphy of the North Sea Basin.
