Every year on January 1st hundreds of works enter the public domain around the world. So how do we know which works will come of age in 2011?
Like [last year](http://blog.okfn.org/2009/11/25/which-works-fall-into-the-public-domain-in-2010/) we are keen to get a picture of this well in advance so we can start planning celebrations for Public Domain Day 2011 (see [here for our round up of the 2010 highlights](http://blog.okfn.org/2010/01/05/public-domain-day-2010-a-roundup/)!).
First off, we can get a rough idea from the data and calculators that are live on our [Public Domain Works](http://publicdomainworks.net/) project:
We are going to be loading a lot more data (e.g. from the British Library and Cambridge University Library) into project very soon, and we also planning to update the calculation code in the light of continued work on the [public domain calculators](http://wiki.okfn.org/PublicDomainCalculators) — so watch this space!
To make sure we haven’t missed anyone, we can cross-reference this with bigger lists of notable people (not just creators) who died in 1940, such as one can find on Wikipedia:
Furthermore one can use structured data sources (such as [DBpedia faceted search](http://dbpedia.neofonie.de/browse/)) to do more sophisticated things such as searching for [people who died in 1940](http://dbpedia.neofonie.de/browse/rdf-type:Person/deathDate-year~:1940~1940/?fc=12) who were [artists](http://dbpedia.neofonie.de/browse/rdf-type:Person/deathDate-year~:1940~1940/rdf-type:Artist/?fc=12&rs=7), [novelists](http://dbpedia.neofonie.de/browse/rdf-type:Person/deathDate-year~:1940~1940/occupation:Novel/?fc=12), or [poets](http://dbpedia.neofonie.de/browse/rdf-type:Person/deathDate-year~:1940~1940/occupation:Poetry/?fc=12).
This gives us the following basic list of famous creators whose work will enter the public domain in 2011 (in many, but unfortunately not all, jurisdictions):
* Isaac Babel
* Walter Benjamin
* John Buchan
* Mikhail Bulgakov
* F. Scott Fitzgerald
* Emma Goldman
* Paul Klee
* Selma Lagerlof
* Leon Trotsky
* Vito Volterra
* Nathanael West

Over the following few weeks we’re going to start planning for Public Domain Day 2011. This will hopefully include the [launch of a new site for reviews of public domain works](http://jonathangray.org/2010/10/17/introducing-the-public-domain-review/):
The excellent European [COMMUNIA project](http://www.communia-project.eu/) is also starting to plan and coordinate activities in this area, which will be collated on their [Public Domain Day](http://publicdomainday.org) site!
