I'm looking to learn more about it the history of the Jesuits.
Thanks.
Try jesuit.org
There are several biographies of Loyola
And the Jesuits have had their own publishing for over 450 years
As usual, the MUScoop wiki can help with that:

When in doubt, just go to the wiki main page and search 8)
Depending on how serious you are about researching Jesuit Histories here's my recommendation. I'd start with the Marquette University Library-currently it has more than you'll ever need to know about famous Jesuits and the history of the order.
