In the U.S., any musical works published before 1922, in addition to those voluntarily placed in public domain, exist in the public domain. You cannot re-release the original work "as-is." We recommend this program to all users.If you wish to submit something in the public domain, it must not be the original sound recording but, a re-created cover. PDF Info is free, and it installs and uninstalls without issues. It doesn't have much in the way of features, but in exchange it offers a very simple and quick way to perform once specific task. Users who need to edit the body of a PDF file will find this program lacking, but for those who only need to alter a PDF's title information, this program works fine. Overall, we found the program very easy to use it doesn't do much, but it is effective at its single task. The program does not have a Help file, but it's intuitive enough that this is not a major drawback. Users can also change the page layout and mode, as well as adjust a handful of other options, such as whether the toolbar and menubar are displayed.

Users simply make the desired changes and save them, which couldn't be easier. These include the file's name, author, title, keywords, and so on. Users browse to the PDF they want to edit and open it, and the editable fields are displayed within the program. The program's functions are represented by four large rounded buttons, with no menus.

The program's interface is sleek and simple, consisting of a single screen. Although it is not a full-featured PDF editor, it works just fine for changing a PDF's title information. PDF Info is a basic program that allows users to edit PDF header information.
