"Preface to the Abridged Form: The Abridged Form of the Mathematical Tables has been arranged primarily for the convenience of those wishing to use a book of tables in tests or examinations. The material included comprises the first 274 pages of logarithmic, trigonometric and other tables taken from the current edition fo the complete Mathematical Tables. Formulae and equations are omitted, but the Abridged Form still provides an extensive collection of tables for general use, fully adequate for all ordinary mathematical operations. Recent additions to the complete tables, which are also found in this collection, include: a fifteen page tabel of natural secants and cosecants; a table of natural logarithms in more convenient and more complete form; a table giving values for the square of the sine and cosine and their product; and a two page, four-place table of logarithms of decimal fractions."
