Chain Procedure and Micro Subjects

Mentions the need for providing facility of browsing among the Main Entries for micro documents. Demonstrates the unhelpfulness of the Class Index Entry (CIE) with Multiple Headings derived by applying the Chain Procedure to the full class number of a micro subject. Suggests (1) deeming a micro subject as a multi-focal one; (2) its division into convenient smaller compound subjects going with one and the same Basic Subject; (3) preparing a Main Entry for each of these compound subjects; and (4) deriving (CIE) from each Class Number by applying the Chain Procedure. Also demonstrates a method of rendering the (CIE) by cyclic permutation of the terms in the Heading and reading it keeping the syntax of its language in tact.
