I notice that 518 has been assigned. Where did it come from? I do not find it in Abridged 13 or Abridged WebDewey. 

In DDC 22, Numerical analysis is relocated from 515 to 518, a new number.  This relocation is indicated in the heading at 518 Numerical analysis [formerly 515].  As of June 15, 2003, WebDewey is based on the DDC 22 database.  The abridged edition is generally released from six months to a year after the release of a new full edition and Abridged 14 will also include 518 (as all three digit numbers used in the full edition are also in the abridged edition). 

The print version of Abridged 14 is expected in early 2004; Abridged 14 is expected to be available in Abridged WebDewey on December 21, 2003.  (Abridged WebDewey is currently based on Abridged 13.)
