Does anyone even know what this is anymore? ...Now that we have the internet and hardly anyone goes to the library these days. They even cut the library hours and staff. In case you didn't know what this was or you'd like to teach your kidlings, Wikipedia defines it here. "The Dewey Decimal Classification (DDC), or Dewey Decimal System, is a proprietary library classification system first published by Melvil Dewey in 1876. It has been revised and expanded through 23 major editions, the latest issued in 2011. The classification was notable in its time because it introduced the concepts of relative location and relative index. It makes use of three-digit Arabic numerals for main classes, with decimals as expansions for more detail. A library assigns a Dewey Decimal number that unambiguously locates a particular volume in a position relative to other books in the library. This makes it easy to find any particular book and return it to its proper place on the library shelves. The system is used in 200,000 libraries in at least 135 countries." Informal Survey: How many of you knew what it was? How many didn't? How many of your kids did? How many of you actually use it today? How many use the internet more than the library these days?
