The original bibliography on the fine structure of diatoms was published in 1993 (Gaul, Ursula et al.) as a combined effort to assemble from the world's literature (1936 - 1988) all available papers on diatom frustule morphology, which have included SEM or TEM photomicrographs. This paper presents the continued literature - search efforts of the Diatom Herbarium (ANSP), covering library research on the subject, published between 1989 and December, 1999. Some earlier entries are included in the bibliography which have, in the meantime, come to our attention. Also included in a separate table are deletions, addenda and corrigenda to the original list. All conditions and limitations are the same as described in the introduction to the first publication.weiterlesen
