Classification of Books in a University Library (with identification code 1279), CLASSIFICATION of Books in a University Library 1279, Books in a University Library/Classification of  1279, UNIVERSITY Library/Classification of Books in 1279, LIBRARY/Classification of Books in University  1279, Books in a University Library/Classification of 1279, LIBRARY/Classification of Books in a University 1279, UNIVERSITY Library/Classification of Books in a 1279. What is required is an expressive title coextensive to the specific subject of the document; 4) Vocabulary control need not be used; and. Mathematical Methods in the Applied Sciences publishes papers dealing with new mathematical methods for the consideration of linear and non-linear, direct and inverse problems for physical relevant processes over time- and space- varying media under certain initial, boundary, transition conditions etc. An index could be said to be as old as human existence. KWIC and KWOC could not solve the problem of the retrieval of irrelevant document. Derived indexing reduces intellectual effort to a minimum and is thus suited to computer operations, which enables to get a variety of outputs from the one input.
