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 timber of dicotyledonous trees could not be classified on microscopic features in harmony with taxonomic practice because botanical systems were still faulty and not generally recognized, and because microscopic descriptions of timber were not uniform enough for compilation. To find whether timber features could be conformed with a botanic taxonomy, a scheme was drafted for the description of secondary wood of dicotyledonous trees based on definite, uniform and comparable characteristics.On this basis short descriptions were compiled of the timber of 93 species and a table was composed of species identical in microscopic structure. The 24 most important characteristics of the 42 families represented were described. Families and species were indexed.
