If you have any questions or comments about these rights and restrictions, please call us.

Unlike most publishers, we don’t impose strict digital rights management software on our users because of the problems it causes. However, years of effort and expenses have gone into these texts and multimedia components which are sold at very low prices. To guide you we have set the following conditions for the use of these materials and hope you find them fair to both the creators and users of our products.

When purchased at the school price, the following terms and conditions apply to using this text:

• Each student in the class (the Authorized User) must have their own copy of the publisher's distribution CD which acts as their license agreement. If the CD doesn't belong to you personally, if someone has previously used the same CD, or if your disc is a copy, your disc is illegal by definition.
• Discs and their contents are not sold, and ownership of them remains with the Publisher. Your purchase of a CD is a user fee for an individual student. When a new class starts, each student in that class must be provided with their own copy of a new and previously uncirculated disc.
• Violation of these terms grants the Publisher the right to block all on-line access to the animations and other resources provided to Authorized Users.
• Authorized Users may use the text but not copy, modify, transfer, or otherwise re-create any portion of the content in whole or in part except as expressly permitted by the Publisher.
• Authorized Users may make a printout of the text for their own personal use but printouts are not to be sold, loaned, or given away to others.
• Authorized Users and instructors can make a personal backup copy but these copies cannot be shared or exchanged with others.
• If you are an instructor, there are no limitations on the number of students you can project the materials for, or on the time period during which you can do it.
• Instructors should request permission from the Publisher should they want to have multiple copies printed locally.
• If you want to put the eTexts on a network or shared computer, each and every user accessing the on-line version must have a personal legal copy of the CD. The book is not to be placed on any computer that students or others can access without such a disc.
• The publisher has the rights to request logs showing access to any on-line posting of the books and be compensated for copies accessed by unauthorized users.

THE ETEXT IS FURNISHED ON AN “AS IS” BASIS AND WITHOUT WARRANTY. THE LICENSOR EXPRESSLY DISCLAIMS ALL WARRANTIES OF MERCHANTABILITY OR WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE. THE LICENSOR SHALL NOT BE LIABLE FOR LOSS OF PROFITS, LOSS OF USE, OR INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES THAT RESULT FROM THE USE OF THIS SOFTWARE, EVEN IF MADE EXPRESSLY AWARE OF THE POSSIBILITY THEREOF

This agreement represents the entire agreement between the Publisher and the Authorized User, and it supersedes any proposals, communication, or prior agreements, oral or written between said parties. If any of the provisions of this agreement are invalid under any applicable statute or rule of law, they are to that extent deemed omitted. This agreement will be governed and construed as if wholly entered into and performed in the Commonwealth of Massachusetts. You acknowledge that you have read this agreement and agree to be bound by its terms and conditions.
