With the permission of the copyright holder you can copy whatever is agreed and make as many copies as agreed.  Look on the publisher's website for information on rights / permissions / clearance: some websites offer online clearance.  When seeking permission bear in mind the following:

• Allow plenty of time.  It can be difficult to track down the right person and publishers can take several weeks to reply.
• Get it in writing and keep it for future reference.
• Be aware that the copyright owner may impose conditions and costs.
• Do not assume that no reply equals consent.
