The access and reproduction policies of the digital collections of ten
leading university digital libraries worldwide are classified according to factors
such as the creation type of the material, acquisition method, copyright
ownership etc. The relationship of these factors is analyzed, showing how
acquisition methods and copyright ownership affect the access and reproduction
policies of digital collections. We conclude with rules about which factors lead
to specific policies. For example, when the library has the copyright of the
material, the reproduction for private use is usually provided free with a credit
to the source or otherwise mostly under fair use provisions, but the commercial
reproduction needs written permission and fees are charged. The extracted
rules, which show the common practice on access and reproduction policies,
constitute the policy model. Finally, conventional policies are mapped onto
digital policies.
