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.
An attempt was made to provide an identification key, to trees of the former Netherlands East Indies, based solely on vegetative features. Most species flower or seed for limited periods. Only wild plants were included and only those reaching a diameter of 40 cm at chest height, a branchless trunk of at least 2 metres and a total height of 10 metres under favourable conditions. Species restricted to the East of the archipelago were omitted through lack of data.Identification required only a x 10 magnifying glass and a sharp knife. The tables include 442 genera from 92 families. The families themselves were not distinguished, as the genus can more easily be defined; the species of one genus have more vegetative features in common than did a family. The features were selected so that the genera appear only in one or a few places in the key and that related genera or even families may be close together.The tables are preceded by an annotated survey of the features used and some remarks on their systematic value.
