Librarians - roberts-sandbox/create-repo GitHub Wiki

Librarians are the Library Role for, well, librarians. It allows the user to create, modify, delete, loan or return Items. It effectively allows the user access to all parts of WP-Librarian except its settings, which are restricted to Library Admins. Because WP-Librarian's role system is separate from WordPress User Roles a user can be a Librarian as well as having any role within the WordPress installation, besides having an account. This allows for users to manage the Library without being given undue access to the WordPress installation.

The Librarian role is checked via the helper wp_lib_is_librarian(), which is defined in the monstrous wp-librarian-helpers.php.
