1. Are you talking about in a book grid? You can sort by the book’s publication date, either newest first or oldest first in the settings of the grid. Mooberry Book Manager does not sort by the date entered into WordPress.
2. Mooberry Book Manager is designed to be used by the author on the author’s website. In this case, the author name would always be the same, and it’s already written all over the website.
There are cases though when you might want to have an Author field. You might be an author who publishes under multiple pen names and has a single website. You might be a small publisher who works with multiple authors. Or you might not be an author at all, and using Mooberry Book Manager for a different purpose, such as for a book club. In those cases you have two options:
To simply display the author name, you could use another field, such as Subtitle, to display that information.
For more advanced handling of author names, use the Mooberry Book Manager Multi-Author plugin. This will allow you to have a bio and photo of each author as well as advanced filtering and sorting on Book Grids based on author.
