I'm curious how you all work with authors who plan to publish some time in the future. Do you somehow keep track, keep contact, or get notification of the publication of a map you have done?

Is it up to the author whether or not you post a finished map before publication of the book? Or to the publisher? Or do you just always wait, and if so, how do you find out when it's ok to post the map in your portfolio?

Cheers,
