Each level of the classification is a number from 0 to 9. This makes MDS/DDC easy to understand and manipulate. It is the choice of most US public and school libraries, and is used around the world. </p> <p> Although Dewey invented his system in 1876, recent editions of his system are in copyright. LibraryThing's Melvil Decimal System is based on the classification work of libraries around the world, whose assignments are not copyrightable. The "schedules" (the words that describe the numbers) come from a pre-copyright <a href="http://www.archive.org/stream/decimalclasific00dewegoog#page/n68/mode/1up">edition of his system</a>, John Mark Ockerbloom's <a href="http://everybodyslibraries.com/free-decimal-correspondence/">Free Decimal System</a>, and member contributions. </p> <p> "Dewmoji" is an emoji versions of the Melvil Decimal
