The rationale for the access delay is to provide eventual access to all would-be users while still requiring the institutions of researchers who need immediate access to keep paying the subscriptions that cover the costs of publication. The marginal costs of distributing an electronic journal to additional users are trivial in comparison to distributing printed copies of the publication. Delayed access publishers spend little or no additional funds while marketing their publications to a broader population than those with personal subscriptions or those affiliated with institutions that have institutional subscriptions or other forms of institutional access.
