+ <p>A month ago, I blogged about my work to automatically check the
+copyright status of IMDB entries, and try to count the number of
+movies listed in IMDB where it is legal to distribute it the Internet.
+I have continued to look for good data sources, and identified a few
+more. The code used to extract information from various data sources
+is available in
+<ahref="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
+git repository</a>, currently available from github.</p>
+
+<p>So far I have identified 3186 unique IMDB title IDs. To gain
+better understanding of the structure of the data set, I created a
+histogram of the year associated with each movie (typically release
+year). It is interesting to notice where the peaks and dips in the
+graph are located. I wonder why they are placed there. I suspect
+World Word II caused the dip around 1940, but what caused the peak
+around 2010?</p>

+
+<p>I've so far identified ten sources for IMDB title IDs for movies in
+the public domain or with a free license. This is the statistics
+reported when running 'make stats' in the git repository:</p>
+
+<pre>
+ 249 entries ( 6 unique) with and 288 without IMDB title ID in free-movies-archive-org-butter.json
+ 2301 entries ( 540 unique) with and 0 without IMDB title ID in free-movies-archive-org-wikidata.json
+ 830 entries ( 29 unique) with and 0 without IMDB title ID in free-movies-icheckmovies-archive-mochard.json
+ 2109 entries ( 377 unique) with and 0 without IMDB title ID in free-movies-imdb-pd.json
+ 291 entries ( 122 unique) with and 0 without IMDB title ID in free-movies-letterboxd-pd.json
+ 144 entries ( 135 unique) with and 0 without IMDB title ID in free-movies-manual.json
+ 350 entries ( 1 unique) with and 801 without IMDB title ID in free-movies-publicdomainmovies.json
+ 4 entries ( 0 unique) with and 124 without IMDB title ID in free-movies-publicdomainreview.json
+ 698 entries ( 119 unique) with and 118 without IMDB title ID in free-movies-publicdomaintorrents.json
+ 8 entries ( 8 unique) with and 196 without IMDB title ID in free-movies-vodo.json
+ 3186 unique IMDB title IDs in total
+</pre>
+
+<p>The entries without IMDB title ID are candidates to increase the
+data set, but might equally well be duplicates of entries already
+listed with IMDB title ID in one of the other sources, or represent
+movies that lack a IMDB title ID. I've seen examples of all these
+situations when peeking at the entries without IMDB title ID. Based
+on these data sources, the lower bound for movies listed in IMDB that
+are legal to distribute on the Internet is between 3186 and 4713.
+
+<p>It would be great for improving the accuracy of this measurement,
+if the various sources added IMDB title ID to their metadata. I have
+tried to reach the people behind the various sources to ask if they
+are interested in doing this, without any positive replies so far.
+Perhaps you can help me get in touch with the people behind VODO,
+Public Domain Torrents, Public Domain Movies and Public Domain Review
+to try to convince them to add more metadata to their movie entries?</p>
+
+<p>Another way you could help is by adding pages to Wikipedia about
+movies that are legal to distribute on the Internet. If such page
+exist and include a link to both IMDB and The Internet Archive, the
+script used to generate free-movies-archive-org-wikidata.json should
+pick up the mapping as soon as wikidata is updates.</p>
