// EXTRACT AUTHOR'S LAST NAME

// 1. pattern describing delimiter that separates different authors
|

// 2. pattern describing delimiter that separates author name & initials (within one author)

// 3. position of the author whose last name shall be extracted (e.g., "1" will return the 1st author's last name)
