### 3.4.4 Copyright Page

By international treaty, the copyright notice for a book must be either on the title page or on the back of the title page. When the copyright notice is on the back of the title page, that page is customarily not numbered. Therefore, in Texinfo, the information on the copyright page should be within `@titlepage` and `@end titlepage` commands.

Use the `@page` command to cause a page break. To push the copyright notice and the other text on the copyright page towards the bottom of the page, use the following incantantion after `@page`:

    @vskip 0pt plus 1filll

This is a TeX command that is not supported by the Info formatting commands. The `@vskip` command inserts whitespace. The ‘`0pt plus 1filll`’ means to put in zero points of mandatory whitespace, and as much optional whitespace as needed to push the following text to the bottom of the page. Note the use of three ‘`l`’s in the word ‘`filll`’; this is correct.

To insert the copyright text itself, write `@insertcopying` next (see section Document Permissions):

    @insertcopying

Follow the copying text by the publisher, ISBN numbers, cover art credits, and other such information.

Here is an example putting all this together:

    @titlepage
    …
    @page
    @vskip 0pt plus 1filll
    @insertcopying

    Published by …

    Cover art by …
    @end titlepage
