There is a special requirement for the classics and other ancient
works well known within their respective fields of study.
An abbreviated cite to the work is used, without reference to a
particular publication. Because the work is well known to the
readership, it is not included (as a work) in the bibliography.
One way to handle it would be to add a “classical” item type to CSL,
for which bibliography output is never produced. Styles could then
apply a simplified standard style to such references, using only the
author and title fields, plus whatever is entered as the page locator.
