Use the Applies To tab to define which publishing format the profile relates to, which books can be published, and which release state the content must be in.
This is the publishing format used by this profile. When you create a new profile make sure you select the correct publishing format. The format influences the actions available for use in the Actions tab.
Select the template a book must be based on in order to publish using this profile. Alternatively, override this option by selecting All Books, which allows any book in the library to publish using this profile.
Release states control which content can be published, based on the release state that has been applied during the review cycle. For example, only "Released" content should be included in documents published and distributed to external customers. Content in "Draft" should not be included.
