I was disappointed to see the 1927 issues of the Christian Leader (the Universalist denominational magazine) unavailable at the Hathi Trust site. They fell into the public domain on January 1, but since they had been misdated as 1930, they were not available.
A small (but nicely worded) email of complaint to the people at the Hathi Trust got a reply. The original scanner would have to examine and re-date the files to open them up. And they did.
Enjoy a Universalist window into 1927. (Hathi Trust)
(Now, who do I have to write at Harvard to get the issues from the 1930s to the mid 1950s included in their scanning program? They did the later ones.)
