Klotzkubaturen – Kubični sadržaj klada (3 decimale)

Klotzkubaturen – Cubic content of logs (tables for calculating the cubic capacity of round logs), 3 decimal places are practical auxiliary tables for quickly calculating the cubic capacity of round logs (logs) based on diameter and length, with an accuracy of three decimal places.

The book was published by Drvotrzac A. Blau from Zagreb, a reputable company of Adolf Blau that dealt in the trade of wood, paper and publishing of professional literature. Adolf Blau (1886–1944) was a well-known Zagreb publisher and merchant of Jewish origin, whose company published useful tables and manuals for the forestry and woodworking professions. For Germany and Austria, the book was distributed through the Viennese publisher W. Frick.

At a time when the timber industry was a significant economic sector in the Kingdom of Yugoslavia, such tables enabled quick and precise calculation of log volumes when selling, buying and processing timber, thus saving time for foresters, traders and sawmills. The work is part of a wider series of Fink's Holzrechentafeln (timber calculation tables), which also included calculations of board areas and other useful calculations.

The 1929 edition (small format, cardboard binding) was intended for practical everyday use in the field and in offices. Today it represents an interesting rarity for historians of economics, forestry and industrial archaeology, testifying to the developed timber profession in interwar Croatia and its connections with German-Austrian technical knowledge. It is sought after by collectors of professional literature and antiquarians.
