If you have enabled the DOI plugin and assigned a DOI to the monograph, it should display on the catalog page. There is no special setting to make the DOI display. Maybe try clearing your cache and reloading the page?

Slashes “/” shouldn’t be used in DOIs. You should something else, such as dots or underscores. We strongly suggest that you use the plugin’s default patterns to generate your DOIs because that limits this kind of issues.
You also need to submit your DOIs for registration to CrossRef. Have you done that? There is no CrossRef plugin for OMP which does this automatically so you will have to do it manually.

With automatically generated DOIs, the DOI doesn’t get assigned until the first time that the object is accessed publicly. I’m not sure exactly how this works with manually assigned DOIs, but it could be that the DOI won’t appear on the public page for the book until a user has accessed the book. I noticed that you haven’t posted a file for the book yet and so no one has publicly accessed it yet.

try to manually set a publication date for the PDF (in Catalog Entry). In our installation, you need to add one otherwise the DOI will not be shown. As far as I now, DOIs can also only be regististered if they have a publication date.
