Open access has become an issue of concern in recent years. Open access policies have been adopted by domestic and foreign governments and institutions, with the result that government information and academic research materials have been made available to the public. Museums have also become increasingly concerned with the adoption of open access policies for their digital collections. However, despite the publishing of academic papers, initiatives put forth by non-profit organizations, and the examples set by major museums, as of now only a small number of museums worldwide have adopted such policies, which is in contrast to the public nature of museums. It is worthwhile to explore why many museums have not yet adopted open access policies. Different points of view regarding the adoption of open access policies for museum digital images are illustrated in this article. It is argued that museums are able to reasonably and effectively implement such policies. Finally, suggestions are provided for future studies and the museum community in the hope of accelerating the adoption of open access policies.
