Events

PEN World Voices Festival (Monday through May 1) This free annual literary event, which brings about 150 writers from 30 countries to venues spread throughout the New York City, is back with a focus on Mexico — stories about migration, border control and national identity. Speakers include authors like Salman Rushdie, Yuri Herrera and Jamaica Kincaid; and events like “I Wish to Say” with Sheryl Oring, a prolific writer of postcards to presidents. She and other writers will be at Bryant Park on Tuesday at 12:30 p.m. typing audience dictations of postcards to current presidential candidates. The full lineup for the event can be found at worldvoices.pen.org. And on Wednesday, at 6:30 p.m., the Tenement Museum will present a special edition of its Tenement Talks series as part of the festival. It will feature eight writers, including Colm Tóibín, reading from their work with the venue’s worldly history in mind. 103 Orchard Street, at Delancey Street, Lower East Side, 877-975-3786, tenement.org.
