Many publishers allow a pre-print (not peer-reviewed) or peer-reviewed postprint (final draft adn peer-reviewed, but not publishers' final PDF version) to be deposited in an institutional repository such as WIReDSpace. Some publishers even allow their final PDF version (published version) to be deposited. For information about publishers' copyright policies, please check SHERPA/ROMeO website
Many publishers allow the final PDF published version of a work to be deposited in an institutional repository, like WIReDSpace.
Authors wanting to deposit copies of their articles onto WIReDSpace need to check the Copyright Policies first. If the publisher allows a pre-print, postprint or the final PDF version, then the author can go ahead and load their works, without requesting permission from the publishers. Generally a link from the work on WIReDSpace is made to the published version on the publishers' website.
Citations should be made to the published works, not pre-print or postprint versions.
Many funding organisations and agencies have policies that stipulate that scholarly authors need to deposit copies of their pubilcations in an Open Access environment, such as an institutional repository or open research archive.
