PEN America launched the U.S. Safety Program - training and resources for authors, illustrators, and translators who are facing threats and abuse online and at events. Hachette, Macmillan, Penguin Random House, and others have chipped in close to a million dollars, and fundraisers like name auctions for future novels are aimed at keeping the program funded beyond press releases.
The group frames it as a response to censorship campaigns and harassment that have hit writers of challenged books especially hard. For anyone touring or posting about their work, it's a rare example of publishers and literary organizations pooling money for concrete safety help instead of leaving individuals to manage it alone.
