Libraries previously had given books permanent shelf locations that were related to the order of acquisition rather than topic. The classification&amp;#039;s notation makes use of three-digit numbers for main classes, with fractional decimals allowing expansion for further detail. Numbers are flexible to the degree that they can be expanded in linear fashion to cover special aspects of general subjects.&amp;lt;ref&amp;gt;Chapter 17 in {{cite book |last1=Joudrey|first1=Daniel N.|last2=Taylor|first2=Arlene G.|last3=Miller|first3=David P.|title=Introduction to Cataloging and Classification|date=2015|publisher=Libraries Unlimited/ABC-CLIO|location=Santa Barbara, CA|edition=11th|isbn = 978-1-59884-856-4}}&amp;lt;/ref&amp;gt; A library assigns a classification number that unambiguously locates a particular volume in a position relative to other books in the library, on the basis of its subject. The number makes it possible to find any book and to return it to its proper place on the library shelves.&amp;lt;ref group=&amp;quot;Note&amp;quot;&amp;gt;Consider as an example a book on the network protocol IPv6.  It will be located at 004.62, after general networking books (004.6) but before peripherals (004.7). It can thus be placed on the shelf in the correct location.&amp;lt;/ref&amp;gt; The classification system is used in 200,000 libraries in at least 135 countries.&amp;lt;ref&amp;gt;{{cite web&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Over time it added some aspects of a [[faceted classification]] scheme, allowing classifiers to construct a number by combining a class number for a topic with an entry from a separate table. Tables cover commonly used elements such as geographical and temporal aspects, language, and bibliographic forms. For example, a class number could be constructed using 330 for economics +&amp;amp;nbsp;.9 for geographic treatment +&amp;amp;nbsp;.04 for Europe to create the class 330.94 European economy. Or one could combine the class 973 (for the United States) +&amp;amp;nbsp;.05 (for [[periodical]] publications on the topic) to arrive at the number 973.05 for periodicals concerning the United States generally. The classification also makes use of mnemonics in some areas, such that the number 5 represents the country Italy in classification numbers like 945 (history of Italy), 450 (Italian language), and 195 (Italian philosophy). The combination of faceting and mnemonics makes the classification &amp;#039;&amp;#039;synthetic&amp;#039;&amp;#039; in nature, with meaning built into parts of the classification number.&amp;lt;ref&amp;gt;{{harvp|Chan|2007|p=331}}&amp;lt;/ref&amp;gt;&lt;/div&gt;&lt;/td&gt;&lt;td class=&quot;diff-marker&quot;&gt;&lt;/td&gt;&lt;td style=&quot;background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The classification was originally enumerative, meaning that it listed all of the classes explicitly in the schedules.
