That's way way way too much info for a select. Or any other mechanism.
When faced with a situation where a user must select from a large dataset, I present them with what I've called a "picker": a popup window (actually a floating div rather than a new window) that allows them to page and search through the data to locate their selection(s). That way they are not overwhelmed with a huge amount of data.
