Discussion on rights and values has emerged in relation to e-books. Vendors must be made aware of and asked to respect library values and requirements, as well as the rights accorded to libraries under legislation, if e-book enterprises are to remain both economically viable and desirable. Algenio and Thompson-Young describe the conflict between libraries and publishers as one of values (2003, 114). Publishers seek to increase profits through product differentiation and protection of their intellectual property through licensing agreements and digital rights management technology. Libraries desire widespread access to electronic material through shared technological platforms and the full right to use copyrighted material for educational advancement within the limits prescribed by law These conflicting sets of values have led to issues of power in the development of business models for e-books. Algenio and Thompson-Young note, “libraries‟ purchasing power has not yet reached a critical mass,” and for this reason “publishers have the advantage to push certain prices and licensing terms” (2003, 119). Coyle supports this claim, and argues that the digital rights management technology used in e-books and protected through licenses has resulted in a situation where anything not explicitly permitted by the terms in the license is forbidden (2001, 321). This essentially gives rights holders the ability to ignore copyright law and has significant implications for access, scholarship and fair dealing.
