+ <description><p>I've continued to track down list of movies that are legal to
+distribute on the Internet, and identified more than 11,000 title IDs
+in The Internet Movie Database so far. Most of them (57%) are feature
+films from USA published before 1923. I've also tracked down more
+than 24,000 movies I have not yet been able to map to IMDB title ID,
+so the real number could be a lot higher. According to the front web
+page for <a href="https://retrofilmvault.com/">Retro Film Vault</A>,
+there are 44,000 public domain films, so I guess there are still some
+left to identify.</p>
+
+<p>The complete data set is available from
+<a href="https://github.com/petterreinholdtsen/public-domain-free-imdb">a
+public git repository</a>, including the scripts used to create it.
+Most of the data is collected using web scraping, for example from the
+"product catalog" of companies selling copies of public domain movies,
+but any source I find believable is used. I've so far had to throw
+out three sources because I did not trust the public domain status of
+the movies listed.</p>
+
+<p>Anyway, this is the summary of the 28 collected data sources so
+far:</p>
+
+<p><pre>
+ 2352 entries ( 66 unique) with and 15983 without IMDB title ID in free-movies-archive-org-search.json
+ 2302 entries ( 120 unique) with and 0 without IMDB title ID in free-movies-archive-org-wikidata.json

+ 182 entries ( 100 unique) with and 0 without IMDB title ID in free-movies-letterboxd-silent.json
+ 229 entries ( 87 unique) with and 1 without IMDB title ID in free-movies-manual.json
+ 44 entries ( 2 unique) with and 64 without IMDB title ID in free-movies-openflix.json
+ 291 entries ( 33 unique) with and 474 without IMDB title ID in free-movies-profilms-pd.json
+ 211 entries ( 7 unique) with and 0 without IMDB title ID in free-movies-publicdomainmovies-info.json
+ 1232 entries ( 57 unique) with and 1875 without IMDB title ID in free-movies-publicdomainmovies-net.json
+ 46 entries ( 13 unique) with and 81 without IMDB title ID in free-movies-publicdomainreview.json
+ 698 entries ( 64 unique) with and 118 without IMDB title ID in free-movies-publicdomaintorrents.json
+ 1758 entries ( 882 unique) with and 3786 without IMDB title ID in free-movies-retrofilmvault.json
+ 16 entries ( 0 unique) with and 0 without IMDB title ID in free-movies-thehillproductions.json
+ 63 entries ( 16 unique) with and 141 without IMDB title ID in free-movies-vodo.json
+11583 unique IMDB title IDs in total, 8724 only in one list, 24647 without IMDB title ID
+</pre></p>
+
+<p> I keep finding more data sources. I found the cinemovies source
+just a few days ago, and as you can see from the summary, it extended
+my list with 63 movies. Check out the mklist-* scripts in the git
+repository if you are curious how the lists are created. Many of the
+titles are extracted using searches on IMDB, where I look for the
+title and year, and accept search results with only one movie listed
+if the year matches. This allow me to automatically use many lists of
+movies without IMDB title ID references at the cost of increasing the
+risk of wrongly identify a IMDB title ID as public domain. So far my
+random manual checks have indicated that the method is solid, but I
+really wish all lists of public domain movies would include unique
+movie identifier like the IMDB title ID. It would make the job of
+counting movies in the public domain a lot easier.</p>

- <title>A one-way wall on the border?</title>

- <description><p>I find it fascinating how many of the people being locked inside
-the proposed border wall between USA and Mexico support the idea. The
-proposal to keep Mexicans out reminds me of
-<a href="http://www.history.com/news/10-things-you-may-not-know-about-the-berlin-wall">the
-propaganda twist from the East Germany government</a> calling the wall
-the “Antifascist Bulwark” after erecting the Berlin Wall, claiming
-that the wall was erected to keep enemies from creeping into East
-Germany, while it was obvious to the people locked inside it that it
-was erected to keep the people from escaping.</p>
-
-<p>Do the people in USA supporting this wall really believe it is a
-one way wall, only keeping people on the outside from getting in,
-while not keeping people in the inside from getting out?</p>
