Prestel is an imprint of Penguin Random House that focuses on art, architecture, design, and photography. If you’ve been to more than one major art gallery opening in the past decade in North America, chances are you’ve encountered one of their many exhibit catalogues. Their logo was immediately familiar to me for this reason.
The vast majority of what they accept is by people with established careers, however if you have a project that is a good fit for them, they are open to direct submissions
You can get a good idea for what they publish by visiting their bookshop here. If you go to their lifestyle page, you can see that they also publish cookbooks.
There are no guidelines for the proposals, all they say is which email address you should submit them to. You can access that information, by going to this page and scrolling down.
Emily Harstone is the author of many popular books, including The Authors Publish Guide to Manuscript Submissions, Submit, Publish, Repeat, and The 2021 Guide to Manuscript Publishers.
She regularly teaches three acclaimed courses on writing and publishing at The Writer’s Workshop at Authors Publish. You can follow her on Facebook here.
