Today, I read an article "National Library of China to add its records to OCLC WorldCat" (more information at: http://www.oclc.org/news/releases/20085.htm), in Nextspace, No. 9, published by OCLC. Since the later part of the last year, there have been many discussions about the cooperation between NLC and OCLC. The cooperation was first announced in August 2007 during the WLIC in Durban, and the agreement was signed at the beginning of 2008.
However, we have submitted several batches of test records to OCLC until the end of July. I think the last test file is about to be passed, and we will submit our full records to OCLC in the next couple of months.
