NON CONVENTIONAL INDEXING MODEL - CITATION INDEXING

Another unique indexing model was developed by Eugene Garfield in early 1960's. The model is non conventional in the sense that  it does not use subject terms in indexing. Instead, the indexing is  done  by  the name of author - cited and  citing references to sources. Here, the name  of the author, the source  document where  a particular paper is published  is taken  into consideration. The author and the source document  cited are  considered for indexing. This indexing named  as  Citation Indexing and developed on the same idea of Shepherd's Citation index is a unique example of  a non conventional model. Here, the problems of citation order, semantics, change of terminologies of a subject are automatically solved, as it is not based on terminologies.  Studies have shown  that  it works quite well in providing subject approach to information. The Science Citation Index, Social Science Citation Index and Arts and Humanities Citation Index are the examples of this model.
