 note = {application/pdf, IDP000715_001, The development of digital technology has drastically changed scholarly communication. T he advent of electronic journals has changed the industrial structure of academic publish-i ng. As the market concentration of journal publishing continues to increase, the pricing of j ournals has been dominated and controlled by large publishers. The never-ending rise of s ubscription prices is approaching a tipping point that libraries/institutions—even in hi gh-income countries—can no longer bear. In these circumstances, the open access (OA) m ovement has been promoted over the past 15 years, and new types of publications have ap peared. This paper discusses the definition and history of OA, the position of each stake- holder in the OA landscape, and new digital-age journals, which include OA mega-journals  and research funders’ OA platforms.},
