    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

To facilitate further discussions and to inform tropical forestry experts, the formation and anatomy of bark were reviewed in association with its terminology. Sections deal with: secondary phloem; dilation and sclerosis; their influence on primary bark parts and on secondary phloem; interxylary phloem; pith ducts; periderm; lenticels and dead outer bark. Next follows an analysis of what could usually be seen of the anatomy of the bark and the crust with a x 10 lens and with the naked eye. The features noticed were then evaluated as distinctions for bark species. Information was given on odour and taste.

Then follow descriptions of 60 investigated barks of the Indonesian Archipelago, analysed by these means. A x 10 lens proved sufficient for identification.

The sequence of bark features from common to special features was shown to be usually: cork layer, stone cells, fibres, soft bark parts, secretory organs, bark rays, while the primary bark parts, often having disappeared, could only serve as distinguishing features for a limited number of barks.

If the number of bark parts considered were to be further enlarged the use of a x 20 lens might become necessary.
