摘要:Over the last two months, I have had many emails and Zoom conversations about why ACS is now launching a suite of nine subdiscipline-specific open access journals, collectively called ACS Au (Figure 1). Some of these conversations have revolved around “why now”, and others focused on “why open access”. However, most of these discussions have been centered on “why we need another ACS journal in each of the nine subdiscipline-specific areas when we already have a set of world-class traditional hybrid journals”.
