    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.

It was of importance in the evaluation of feedingstufrs to know its quantitative composition. A qualitative botanical indicated purity but a quantitative test was needed for the degree of purity. Natural feedstuffs always contained a certain amount of foreign material, which could be considered either as natural or chance contamination. The manufacturer had to ensure that commercial feedstuffs had a high degree of purity. Whenever there was consideration in the trade of standards for purity, it was necessary to be able to check these standards.

Ezendam worked out a method of measuring impurities both quantitatively and qualitatively. It was tested on some feedstuffs and thus led the way for microscopic study of feedingstuffs.
