Hi, Frederic: you may see "Obtaining the Dewey Decimal Classification Number from other databases: a catalog clean-up project" [1] where MARC21 or Unimarc sources (through Z39.50, SRU, web scraping...) where used to enrich our catalog. The batch and the online version of Dewey import processes are presented in [2]. HTH. Stefano [1] http://leo.cineca.it/index.php/jlis/article/view/8766 [2] http://www.slideshare.net/stefanobargioni/bargioni-dewey

I want to collect dewey codes to complete my database. I was thinking about using z39.50 servers to get them but I have 2questions: - I want to use 2 different servers; one in marc21 and one in unimarc. As z39.50 only works for servers using the same format as me, Is there a way to collect the dewey code of the other server with an alternative? What about SRU ? - My second question is: When importing that dewey code, I dont want other data (like title author etc) to overwrite mines. How can I do that?

Thx for responses,

Frederic Edmont
