Title field for books that belong to more than one series

[Michele]

Hi -

What is the appropriate syntax for series info in the title field when a book belongs to more than one series? For example:

Title (series 1; series 2)
Title (series 1) (series 2)
Title (series 1, series2)

Thanks

Michele

Title (series 1; series 2)

Only the first-listed series name will appear over the title on the book page.

Thanks!
