Short and sweet today: I forgot to acknowledge Public Domain Day on January 1, 2023. This year, items published in 1927 entered the domain, including Virginia Woolf’s To The Lighthouse and the classic Ice Cream song of which Howard Johnson is one of the writers.
Duke’s Center for the Study of the Public Domain have a list of the most interesting ones a well as good information about copyright and the importance of the public domain. Wikipedia, of course, is a treasure trove of information, and I am a supporter of The Public Domain Review, an online journal devoted to celebrating the public domain. They send an interesting collection of postcards a few times a year.
Have fun browsing!
