Publication Source is a single line text field used to display the official title of the journal, book, or other medium in which the document was published.
If entering a book chapter, list the name of the book in this field. Publication Source should be capitalized using Headline Style Capitalization (see Title for more information). Special characters will need to be formatted using HTML tags.
To find a journal's official title, search for it using UlrichsWeb (Penn proxy required if off campus) and find "Title" under "Basic Description." It's not uncommon for journals to change names over time, the details of which can be found under "Title History Details" (when applicable).
