blank lines. A bibliographic reference is a set of lines that contain bibliographic information fields. Each field starts on a line
beginning with a `%', followed by a key-letter, followed by a blank, and followed by the contents of the field, which continues until the
next line starting with `%'. The most common key-letters and the corresponding fields are:
A Author name
