    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.

The author's procedures and methods were described for compiling General Volume Tables for teak, from which Local Tables can be derived. Only easily and rather accurately measurable characteristics should be used: tree height, length of trunk free of branches and timber-yielding length of trunk and trunk girth at 1.30 metre. Girthes at 1.50 metre and 1.70 metre were also necessary, to avoid abnormal trunk bases. The Table should also contain estimated volumes of whole tree and its parts with bark, and diameter, girths and volumes of the tree without bark at different heights.

But more data were needed to construct the Table, primarily the mathematical expression of the trunk form. Two true form quotients are required to represent the trunk form of teak with satisfactory accuracy in a simple equation. Estimation of the form class of an individual tree was only possible by direct measurements, so average form classes were used. These classes for the various trees and stands of one single kind of wood usually varied so little that for any one Table practically only one form class was required. The slight variation in form class of teak can easily be incorporated in the Volume Tables.
