Errata Editions publishes books of educational and cultural value for a wide audience with a special focus on rare photography books which are unavailable to students and new generations of photographers. We are a group of practicing photographers, designers and educators who share a common love for the mediums of photography and book craft.

Errata Editions was founded in 2008 by Valerie Sonnenthal, Jeffrey Ladd and Ed Grazda.

Valerie Sonnenthal (Publisher) has a Masters of Library Science degree and worked as a Photo Editor for nearly thirty years, with Aperture, ARTnews, Vanity Fair, Magnum Photo Agency, The New York Post, The Associated Press and fine art photographers. She curated the DTW Gallery for nearly a decade at New York's Dance Theater Workshop giving many photographers their first one-person shows. Her artwork has been exhibited in galleries both in the US and abroad. Her writing regularly appears in the Martha's Vineyard Times.
