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 — 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

Almost everything is covered by either regular copyright, or if it is a public service department, 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 [11]. 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 [12].

Deprecated

• {{PD}} — Non-specific public domain tag. Use a more specific one from the list above instead.
• {{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.
