Please help to index our OMP to google scholar: https://ebook.borneonovelty.com/index.php/repository/index
In recent versions, OMP has been updated to be compatible with Google Scholar indexing. It could be that there is an aspect of your instance that is not configured correctly, however. You may want to have a look at our troubleshooting guide here: https://docs.pkp.sfu.ca/google-scholar/en/#troubleshooting-for-journal-managers-and-editors
It is mostly written for OJS, so, not all of it will apply, but there will be aspects that do.
