Template for anonymous works which were in the public domain on the URAA date (usually 1/1/1996). Note that anonymous works are (usually) works where the author was not publicly identified, and not just works published or installed without the author's name. In addition, in most countries, works published anonymously no longer qualify as anonymous works if the author is publicly identified later (details vary). See Commons:Anonymous works.
A file description page for an anonymous work must make clear (i) why the work is public domain in the United States and (ii) why it is public domain in the source country (if not the US). The reason parameter is often useful for the second part.
To add your language to the list of languages supported by this template, please copy the code of Template:PD-anon-auto-1996/en (or any other language version you prefer to translate) and replace the text strings in there (the form below can be used to create a translation, the English version is preloaded in the edit box). Please change the parameter lang from en (or whatever language you are translating) to the language code of your language.
