You need to purchase your own based on the number of computers with the fonts. You can contact H&F-J about an educational discount and negotiate if circumstances require, but you need to license the font. You will never own a font unless you design it yourself.
I am currently doing environmental graphics for a collegiate arena. The campus recently standardized all exterior building signage as Whitney semi-bold [Hoefler & Frere-Jones], under the direction of a different design consultant.
If that university purchased Whitney for the other design consultant to use, should my design group have access to that typeface too? Or do we need the university to purchase another license, as we are two separate businesses?
I know this is a basic question, but one must learn these things along the way ...
