   5 <p>I've continued to track down list of movies that are legal to
   6 distribute on the Internet, and identified more than 11,000 title IDs
   7 in The Internet Movie Database (IMDB) so far.  Most of them (57%) are
   8 feature films from USA published before 1923.  I've also tracked down
   9 more than 24,000 movies I have not yet been able to map to IMDB title
  10 ID, so the real number could be a lot higher.  According to the front
  11 web page for <a href="https://retrofilmvault.com/">Retro Film
  12 Vault</A>, there are 44,000 public domain films, so I guess there are
  13 still some left to identify.</p>
  14
  15 <p>The complete data set is available from
  16 <a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
  17 public git repository</a>, including the scripts used to create it.
  18 Most of the data is collected using web scraping, for example from the
  19 "product catalog" of companies selling copies of public domain movies,
  20 but any source I find believable is used.  I've so far had to throw
  21 out three sources because I did not trust the public domain status of
  22 the movies listed.</p>
  23
  24 <p>Anyway, this is the summary of the 28 collected data sources so
  25 far:</p>

  56 <p> I keep finding more data sources.  I found the cinemovies source
  57 just a few days ago, and as you can see from the summary, it extended
  58 my list with 63 movies.  Check out the mklist-* scripts in the git
  59 repository if you are curious how the lists are created.  Many of the
  60 titles are extracted using searches on IMDB, where I look for the
  61 title and year, and accept search results with only one movie listed
  62 if the year matches.  This allow me to automatically use many lists of
  63 movies without IMDB title ID references at the cost of increasing the
  64 risk of wrongly identify a IMDB title ID as public domain.  So far my
  65 random manual checks have indicated that the method is solid, but I
  66 really wish all lists of public domain movies would include unique
  67 movie identifier like the IMDB title ID.  It would make the job of
  68 counting movies in the public domain a lot easier.</p>
