Libraries with ongoing subscriptions to WebDewey in CORC or Dewey for Windows may post the DDC21 Summaries (i.e., the first three levels of the Dewey Decimal Classification - for example, 500 Science is Level 1, 510 Mathematics is Level 2, 513 Arithmetic is Level 3) on their web sites solely for the internal, noncommercial purpose of organizing the resources made available to their patrons via such web sites. Such use of the DDC 21 Summaries should be accompanied by the following notice on the initial screen:
