The Public Domain in 2011

According to (which I helped build) there were 661 people whose works entered the public domain in 2011:

Of course, I should immediately state that this is a fairly crude calculation based on a simple life+70 model and therefore not applicable to e.g. the US with its 1923 cut-off (for those interested in the details of computing public domain status there’s you can find lots more here:

The figure is also a significant underestimate — to do these calculations you need lots of information about authors, their death dates and their works. This kind of bibliographic metadata has, until fairly recently, been very hard to come in an open data form and so we have been limited to doing calculations with only a relatively small subset of the actual all works (though, it should be said, we do have many of the most ‘important’ authors).

Thankfully this is now changing thanks to people like the British Library opening up their data so we should see a much extended list for 2011 some time in the next few months (if you’re interested in open bibliographic data, you should join the Open Knowledge Foundation’s Open Bibliographic Data Working Group).

Launch of the Public Domain Review

Lastly, I have an exciting announcement. Thanks to the work of my Open Knowledge Foundation colleague Jonathan Gray, we’re pleased to announce the Launch of the Public Domain Review to celebrate Public Domain Day 2011:

As Jonathan explains in the blog post:

The 1st of January every year is Public Domain Day, when new works enter the public domain in many (though unfortunately not all) countries around the world.

To celebrate, the Open Knowledge Foundation is launching the Public Domain Review, a web-based review of works which have entered the public domain:

Each week an invited contributor will present an interesting or curious work with a brief accompanying text giving context, commentary and criticism. The first piece takes a look at works by Nathanael West, whose works enter the public domain today in many jurisdictions.

You can sign up to receive the review in your inbox via email. If you’re on Twitter, you can also follow @publicdomainrev. Happy Public Domain Day!

    Thanks for starting this;

    What I am looking for is a site that offers musical recordings (I guess 78 rpm records only, unfortunately, don’t bother with wax rolls and the like) that have entered into the public domain. The idea is to publish these as complete albums, complete with cover art where possible, and in lossy (.ogg) and lossless formats (flac) downloadable as 7-Zip archives (to ensure integrity). Ideally the site offers metadata to allow for easy searching, offer streaming previews, and allow for easy iPod (etc.) integration.

    I have searched far and wide but there isn’t really a “sound recording” (as in musical work) Public Domain yet. A good example would be where CC-works are available. A bad example would be the US LoC National Jukebox (one cannot download as even works from 1900AD are still under “state law” copyright).
