Abstract : The open access (OA) principle requires that scientific information be
made widely and readily available to society. Defined in 2003 as a “comprehensive
source of human knowledge and cultural heritage that has been approved by the
scientific community”, open access implies that content be openly accessible and this
needs the active commitment of each and every individual producer of scientific
knowledge.
Today, the success of the open access initiative cannot be denied. Yet, in spite of the
growing success of the open access initiative, a significant part of scientific and
technical information remains unavailable on the web or circulates with restrictions.
Even in institutional repositories (IR) created to provide access to the scientific
output of an academic institution and central vector of the so-called green road to
open access, more or less important sectors of the scientific production are missing.
This is because of lack of awareness, embargo, deposit of metadata without full text, confidential content etc.
This problem concerns in particular electronic theses and dissertations (ETDs) that
are disseminated with different statuses – some are freely available, others are under
embargo, confidential, restricted to campus access (encrypted or not) or not available
at all. While other papers may be available through alternative channels (journals,
monographs etc.), ETDs most often are not.
Our paper describes a new and unexpected effect of the development of digital
libraries and open access, as a paradoxical practice of hiding information from the
scientific community and society, partly while sharing it with a restricted population
(campus). We try to explain these different shades of grey literature in terms of
different degrees of secrecy related to intellectual property, legitimate interests,
expected exploitation and trade secrets, and suggest some ways of increasing
availability of ETDs in an open environment (inter-lending loan and document
supply, alternative format etc.). The study builds on a review of recent papers on
ETDs in institutional repositories and provides empirical evidence on this reality.
The study also includes an overview of the thesis mandate policies of IR as
mentioned in the ROARMAP directory, and an evaluation of the availability of
ETDs in a small panel of European and American academic IR, networks and
institutions.
