[edit] Copyright issue?

Is this list a copyvio? Is this a trademark violation? Is Wikipedia at risk? See:

Since the article includes live links, Wikipedia is actually using the Dewey as a classification system, something which the copyright owner requires websites to purchase a license for:

[edit] Copyvio?

Is the list in the article (which might be better on a seperate list page) a possible violation of a database copyright (as the article itself says copyright is claimed on the system)? I think it could be fair use as it is difficult to talk about DDC in an encyclopedia without including a copy of the system. Joe Llywelyn Griffith Blakesley talk contrib 12:40, 6 August 2006 (UTC)

OCLC has a PDF on its web site that gives the DDC numbers for the first 3 digits of DDC. In their contract, they say that libraries can display the first 3 digits to the public, but no more. So I think this is the allowed portion and therefore there isn't a problem. LaMona 01:54, 15 September 2006 (UTC)
