Usage

All field names must be in lowercase.

Copy a blank version to use. Remember to use the "|" (pipe) character between each field. Please delete any unused fields to avoid clutter in the edit window.

No templates or magic words are necessary when using an ISBN, OCLC number, or Digital object identifier (DOI) as an identifier. Instead of using the id field in these instances, simply use the appropriate field. For instance, type isbn= followed by the number instead of id=ISBN.
