As part of the innovative Signale publishing model, nearly every book published under the main Signale series is made available on an open access basis four years after initial publication. These ebooks may be viewed or downloaded free of charge on a variety of platforms (JSTOR, Project MUSE, OAPEN, etc.), as well as through such ebook vendors as Amazon, Barnes & Noble, Google Books, etc.

Note that due to rights restrictions, translations published under the Signale|TRANSFER imprint are not available as open access books.
