Universal Decimal Classification. Abridged Edition (PD 1000:2003) Ring bound

Universal decimal classification. Abridged edition (PD 1000:2003) This simplified edition of the Universal Decimal Classification (UDC) contains approximately 4,100 classes and incorporates major changes to the scheme since 1999. The UDC Abridged edition replaces the Pocket Edition and has been abridged from the material in the official UDC database, the Master Reference File. It takes account of official amendments, up to and including those in Extensions and Corrections to the UDC, Number 24, November 2002. It includes the new properties table (1k-02) and new and revised classes for management, religion, population, tourism, social welfare, environment studies, biotechnology and cinema. This abridged version of the UDC will be a useful reference for students studying UDC, as it contains a selection of the most common codes used. It is more portable and compact than the complete UDC, available in two heavy volumes. Organizing information Information is everywhere, but is not necessarily usable. It proliferates at an intimidating rate, and the problem for an information-seeker is to find what is relevant and access what is needed. Finding a way through the overwhelming volume of irrelevant material can be a challenge. There are various aids to doing this some for virtual information (website search engines e.g. Google) and some in either print or electronic form (bibliographies, catalogues, directories). They vary in effectiveness, and when relying on natural language can be limited by problems with words (did you use the right term Are you searching in a single language Are you missing relevant items in other languages). Aside from sheer luck, search strategies are more effective if they can draw on information organized into patterns that correspond to the needs of most users or are at least familiar to them with related items brought together, and unrelated ones excluded in other words, information that has been classified
