The <b>Nippon Decimal Classification</b><span style="font-weight: normal"> (<a href="Japanese_language" title="Japanese language">Japanese</a>: <span lang="ja">日本十進分類法</span>, <a href="Hepburn_romanization" title="Hepburn romanization">Hepburn</a>: <span title="Hepburn transliteration"><i lang="ja-Latn">Nihonjisshinbunruihō</i></span>)</span> (<b>NDC</b>, also called the <b>Nippon Decimal System</b>) is a system of <a href="Library_classification" title="Library classification">library classification</a> developed for mainly Japanese-language books maintained and revised by the <a href="Japan_Library_Association" title="Japan Library Association">Japan Library Association</a> since 1948. Originally developed in 1929 by Kiyoshi Mori, the 10th and latest edition of this system was published in 2014. The decimal notation system is similar to the <a href="Dewey_Decimal_Classification" title="Dewey Decimal Classification">Dewey Decimal System</a>, and the order of main classes is inspired from the <a href="Cutter_Expansive_Classification" title="Cutter Expansive Classification">Cutter Expansive Classification</a>. The system is based upon using a three digit number to classify subjects, where more digits can be added if necessary and a decimal point is used to separate the third and fourth digit. The first division level is called a class, the second level is called a division, and the third level is called a section. Each '1-9' digit is used to represent a specific category, with the digit '0' being used to represent general works.
