Stock car racing:File copyright tags/Public domain

Remember that most images you find on the Web are not public domain, even if they list no explicit copyright information. Images only qualify as being in the public domain if they fall under certain specific categories described below – images ineligible for copyright protection, very old works, works by certain government employees, and works where an explicit disclaimer of copyright has been made in writing by the author.

For a simple chart on US Public Domain regulations (Wikipedia servers are located in the US and fall under US guidelines) see the chart here.

New Zealand government
Publications of the New Zealand government are mostly covered by Crown copyright, which in New Zealand has a 100-year term under Section 26(3)(b) of the Copyright Act 1994. This puts most recent material out of bounds. However, there is an exception to these provisions for some documents:
 * PD-NZSection27: for works created by some New Zealand government entities, which are covered by Section 27(1) of the Copyright Act 1994 . The section excludes from copyright protection the following NZ works: Bills, Acts, regulations, municipal bylaws, Hansard, select committee reports, court judgments, Royal commission reports, commission of inquiry reports, ministerial inquiry reports and statutory inquiry reports. Note that sourcing these from a third party provider that, say, annotated Acts, is dangerous – they would have copyright in those annotations, and/or copyright in a new typographical arrangement.

New Zealand Crown copyright used to only last 50 years, and copyright has expired for government works from 1944 or earlier. Regular copyright provisions (such as a 50-year term) apply to works by Crown entities and state-owned enterprises, not Crown copyright.

Deprecated (no longer being used)

 * PD-Russia: Used for works that were public domain under the Russian copyright law of 1993. Obsolete as of 1 January 2008 due to new Russian legislation.
