* Academic Press offers a plan to libraries in which the library makes a lump sum payment to AP
approximately equal to the total cost of its subscriptions in 1999.  In return the library gets electronic versions of all AP journals and can subscribe to paper versions at 1/4 of the list price.
For institutions that buy into this plan, the marginal costs of journals are only 1/4 of their listed library subscription costs.  But it appears that whether or not your university  subscibes to this plan, the total cost of the journal to your library is approximately equal to the regular listed subscription price and so that is the price I will quote  here.
