Shouldn't the first two bullets be merged? They seem pretty redundant to me; whether or not a photograph is publicly available prior to so-and-so date does not really affect whether or not it could be public domain. :| TelCoNaSpVe :| 00:17, 4 January 2011 (UTC)
- The wording is correct. Under UK law the date on which a photo of unknown authorship was publicly made available can indeed affect whether copyright continues to subsist or not. UK law is quite different from US law in this respect. --MichaelMaggs (talk) 21:57, 4 January 2011 (UTC)
- Yes, but the first two points appear to be unnecessarily wordy and can easily be merged, preferably into a single line like "Any photograph before 1947; or" instead of having separation as it does currently. :| TelCoNaSpVe :| 02:28, 5 January 2011 (UTC)
I cannot find any difference in UK law between engravings and photographs, so I don't think this should allow the one but not the other.
Also, the special treatment of engravings, etc., only applies where the author is known, but there isn't a mechanism for tagging engravings, so it looks like unknown author engravings from before 70 years ago are forbidden by Wikimedia, but allowed by UK law.
- I don't know exactly what the rules are or whether this template is correct, but the rules are complex.
- Standard EU rules for anonymous authors: Copyright expires 70 years after publication. If not published within 70 years from creation, the copyright expires 70 years after publication.
- UK law uses that rule, but denotes such authors as "unknown" instead. The term "anonymous" is defined in an EU directive, and the word "unknown" is defined using different words in the w:Copyright, Designs and Patents Act 1988. I don't know what happens if there is a discrepancy between the words "anonymous" and "unknown", as the United Kingdom is required to follow EU law.
- Article 10 (1) of the w:Copyright Duration Directive tells that the directive doesn't have the effect that any copyright terms are shortened. Therefore, the UK is allowed to keep longer terms for pre-existing works, and is doing this with at least some works.
- Go to  and search for the text "Duration of copyright in existing works". Below those words, you will find a section which tells that you should sometimes use the copyright terms in the w:Copyright Act 1956 instead. As far as I have understood, the Copyright Act 1956 makes references to the w:Copyright Act 1911, so you may have to take a look at that copyright act too.
- In the same document, go down to the section entitled "Perpetual copyright under the Copyright Act 1775". Here you can see that you sometimes need to consult the term in the Copyright Act 1775 in order to correctly determine the copyright term of some works. I don't know whether you need to consult more copyright acts than the ones from 1775, 1911, 1956 and 1988 in order to find the correct UK terms for all different kinds of works.
- The template links to this document which lists various terms for various different situations. Note that making a work available to the public isn't the same thing as publishing it. I assume that the person who made the PDF file has waded through all of the different copyright acts. The PDF file makes references to both photographs and engravings. I think that there are some errors in the PDF file. For example, the effect of the Copyright Act 1775 is not specified. --Stefan4 (talk) 23:54, 8 June 2014 (UTC)
