namespace-information |
description |
the ncid identifier is a sequentially assigned number that
uniquely identifies an NACSIS-CAT bibliographic record. In
November 2006 there were about 8 million bibliographic and
90 million holding records in NACSIS-CAT.
If a record is merged into another or if a record is deleted,
its number is discontinued and never re-used.
Information on NACSIS-CAT is available at
http://www.nii.ac.jp/CAT-ILL/contents-e/e_ncat_top.html.
