If you look at this forum discussion... https://forum.librivox.org/viewtopic.php?p=743803#p743803 https://forum.librivox.org/viewtopic.php?p=743803#p743803 You can see that an audio recording of a book published in 1921 was pulled due to legal letters. Of course, in the US, works from 1921 are all supposed to be in the public domain. But already events like this occur for places other than LibriVox - multi-national companies with large legal departments and law firms on retainers not only assert rights for works from 1923 on, but for works before that as well. Most small companies and organizations can't deal with the time and expense required from these spurious legal threats and are forced to give in. Once TPP passes, things will just get much worse.
