Author Information

Adding author information to your document is optional. A document’s author information is assigned to multiple built-in attributes. These optional attributes can be set and assigned values using the author line or using attribute entries in a document’s header.

Author and email attributes

author: The author attribute represents the sole or first author’s entire name. The attributes firstname, middlename, lastname, and authorinitials are automatically derived from the value of the author attribute. When assigned implicitly via the author line, the value includes all of the characters and words prior to the semicolon (;), angle bracket (<), or the end of the line.
email: The email attribute represents an email address or URL associated with the first author (author). When assigned via the author line, it’s enclosed in a pair of angle brackets (< >).

Name and initials attributes

firstname: The firstname attribute represents the first, forename, or given name of the author. The first word in the value of the author attribute is automatically assigned to firstname.
lastname: The lastname attribute represents the last, surname, or family name of the author. The last word in the value of the author attribute is automatically assigned to lastname.
middlename: If author contains values for firstname and lastname, any remaining words or characters found between these values are assigned to the middlename attribute.
authorinitials: The first character of the firstname, middlename, and lastname attribute values are assigned to the authorinitials attribute.

Multiple author attributes

author_<n>: An author_<n> attribute represents each additional author’s entire name, where <n> is the 1-based index of all of the authors listed on the author line (e.g., author_2, author_3). Additional authors can only be assigned via the author line. Each author’s full name includes all of the characters and words directly after a semicolon (;) but prior to the angle bracket (<), next semicolon (;), or the end of the line. The attributes firstname_<n>, middlename_<n>, lastname_<n>, and authorinitials_<n> are automatically derived from author_<n>.
email_<n>: The email_<n> attribute represents an email address or URL associated with each additional author (author_<n>). It’s enclosed in a pair of angle brackets (< >) on the author line.
firstname_<n>: The first word in the value of the author_<n> attribute is automatically assigned to firstname_<n>.
lastname_<n>: The last word in the value of the author_<n> attribute is automatically assigned to lastname_<n>.
middlename_<n>: If author_<n> contains a firstname_<n> and lastname_<n>, any remaining words or characters found between these two attributes are assigned to the middlename_<n> attribute.
authorinitials_<n>: The first character of the firstname_<n>, middlename_<n>, and lastname_<n> attribute values.
