Electronic/ Digital Rights : 4

Copyright in work you have created is yours. Decisions about how and when the work can be used are also yours.
Do not assign your copyright. Licensing the work on either an exclusive or non-exclusive basis is in most cases sufficient for another party to deal with your work.
'Electronic' or digital rights are separate from print rights. They should not be included in a book contract unless the publisher intends to exploit them and is prepared to offer a separate contract setting out terms, conditions and payment for their use.
Any agreement for use of your work should contain a requirement that the publisher of the work will protect its integrity and identify you as author.
You should have an opportunity to approve a final work which contains your material.
Payment may be either by flat fee or advance/royalty arrangement. Because development costs in the digital medium are often higher but distribution costs are lower, a rapidly escalating royalty rate may be appropriate. Royalty statements should detail items sold (CD-ROM) or number of accesses per period (Online/Internet).
