    Abstract
    The origin of the abridged edition of the Dewey system goes back to 1894 when an outline of 192 pages based on the full 5th Edition (1894) was issued for small public and school libraries of North America. New editions have appeared regularly following closely the publication of new full editions. An abridged version, which is always in one volume, comprises an introduction, schedules, four tables (namely 1, 2, 3 and 4) only, and the relative index and other minor features of the full edition, and has shorter numbers. Abridged 15 is a logical abridgement of the DDC23 (2011) and is a product of a new approach to development of an abridged edition of the DDC. Its content has been derived from the DDC database applying a set of rules to extract the edition using the new (2010) version of the editorial support system. The revision process has been informed by interaction with an always widening and diversified Dewey community at home and abroad. It aims to improve the currency of the schedules continuing to serve as shelving tool while recognizing its 'other' uses as a spinoff of its simplicity and inexpensiveness.

    Abstract
    S. R. Ranganathan (1892-1972) has been called the father of the Indian Library movement. He developed the revolutionary Colon Classification (CC), which was published in seven editions from 1928 to 1987. The evolution of the classification through the editions is discussed. The unique features of the CC are described, including the idea, verbal, and notational planes. Tools for designing and evaluating a system are enshrined in his 55 canons, 22 principles, 13 postulates, and 10 devices. Semantic and syntactic relations are enshrined in his PMEST facet formula, fitted with rounds and levels of facets, and other principles, such as the famous wall-picture principle, for citation order of facets. Briefly explained are facet analysis and number building with its notational base of 74 digits. The entry concludes with a discussion of the extent of use of the CC, its enduring contribution to the science of classification, and its future.

    Abstract
    A study of the 144 publications on the Colon Classification published in the last 15 years was made with the purpose to understand its present situation. The article gives the reason for the selection of the period, describes methodology and scope of the investigation, shows previous attempts of collecting this literature and attempts at an interpretation of results (displayed in 8 tables) according to (1) chronological output, (2) kinds of media, (3) origin of contributions, (4) authors, (5) subjects written about, and (6) neglected areas of study. The 144 publications are listed is a separate bibliography in chronological and alphabetical order

    Rez. in: Mitt VÖB 61(2008) H.1, S.99-103 (M. Sandner): "In der Schriftenreihe "Information Professional Series" möchte der Verlag vielbeschäftigten Angehörigen der Bibliothekszunft leicht lesbares, sehr praxisorientiertes, durch ausgewiesene Autoritäten ihres Faches abgesichertes und aktuelles State-of-the-art-Wissen anbieten. - Der Verfasser des vorliegenden Bandes gilt als solch ein arrivierter Experte in Sachen Wissensorganisation, Klassifikation im Allgemeinen und DDC, Kolonklassifikation und UDK im Besonderen. Er ist Vorstand des Departments für Bibliotheks- und Informationswissenschaft an einer indischen Universität. Seinem Text stellt er einige tiefe Verbeugungen voran: die erste gilt dem 1991 verstorbenen Herausgeber der 20. Ausgabe der DDC, den er als geistigen Koautor mit herein nimmt, die zweite gilt Melvil Dewey und dessen phänomenaler Erfindung (The sun never sets on its ever-spreading empire.), die dritte, den ganzen Text begleitende, gilt - unausgesprochen - dem Konzept der Facettierung von Ranganathan. Satijas erklärte Absicht ist es, Anfängern die DDC22 verständlich zu machen und Anwendern zu nützlichen Einsichten zu verhelfen. Einerseits, so kündigt er im Vorwort an, werde er den philosophischen Hintergrund immer wieder beleuchten, andererseits stelle das Buch einen kompletten Kurs dar: anhand didaktisch ausgewählter Beispiele solle nämlich Schritt für Schritt jeder wichtige Bereich des Klassifikationssystems angesprochen und würden alle Methoden für dessen Anwendung erklärt werden. - Keine geringen Ansprüche, die sich Verlag und Verfasser selbst stellen! Das Äußere des Buches wirkt erfrischend und modern - gerne greift man zu dem einladend bunten Band, der laut Inhaltsverzeichnis klar strukturiert scheint. Nur: wo versteckt sich wohl der angekündigte DDC-Kursteil? ... Fazit: sollte dieses Buch, liebe Leserin, lieber Leser, Ihre erste Lektüre über die DDC sein, dann lesen Sie es nicht allein und vor allem, lesen Sie nicht allein dieses! Sollten Sie aber schon einige Erfahrung mit der Dewey haben, dann werden Sie gewiss mit Gewinn all das heraushören, was ein erfahrener Professor aus der Schule zu plaudern vermag, und das, was nur Satija aus seinem Blick auf die DDC Ihnen eröffnen kann."

    Rez. in: KO 30(2003) no.1, S.44-45 (M. Parameswaran): "The fact that M.P. Satija's Manual of Practical Colon Classification has reached its fourth edition clearly Shows its popularity and usefulness as a textbook. As long as Colon Classification (CC) is taught in Indian universities, the relevance of such a text cannot be questioned. The structure and content of the book has not changed much from its previous edition, but the text has been simplified and new examples were added. According to the author, this is a manual for learners; it is not intended to solve the day to day problems of library professionals. Exercises are not provided, but each chapter contains a large number of examples. The book does not make an effort to rectify any mistake in CC or further supplement the existing rules, but only tries to explain what are the provisions in CC edition 6. The reason for choosing the sixth edition of CC instead of the seventh edition is obvious: edition 7 of CC has become a half cooked product even if it is supported by a strong theory. Schools of library science generally follow edition 6, and so far edition 6 remains the standard edition. The Manual is divided into two parts. Part 1 explains the theoretical principles and Part 11 expounds the practical applications. In Part I, having defined the basic concepts such as Fundamental categories, Rounds and Levels etc., the author further explains common schedules (Space, Time and language schedules), common isolates, various devices, Systems and Specials, Phase relation etc. The chapters an parallel schedules and differential facets will be useful not only to students but also to their teachers. An entire chapter has been devoted to filing sequence. In Part II, a chapter is devoted to each of the main classes (MC). These chapters deal with the rules for facet analysis and synthesis into class numbers. Each chapter contains examples illustrating common isolates, phase relations, various devices and parallel schedules relevant to the main class being introduced.
