For the most part, intellectual property law is still national law, although international treaties affect the content of these laws. See International and Foreign Legal Research, available at UIC Law Library - 6th Floor (Reserve) - K85.H64 2008.
WIPO Lex includes more than 10,000 intellectual property laws and regulations from nearly 200 countries. It also includes more than 250 IP-related treaties.
If you cannot find a national copyright law via WIPO Lex, you might try searching the UNESCO Database of National Cultural Heritage Laws.
