First of all, happy new year.
Second, another year, means another batch of writers and visual artists are in the public domain.
Consider using for your own work, the work of Joseph Schumpeter, George Orwell, Marcel Mauss, Rafael Sabatini, Edgar Rice Burroughs, Kurt Weill, Eliel Saarinen, Olaf Stapledon, George Bernard Shaw, Sri Aurobindo, and Max Beckmann.
