The ACM will make all its publications open access starting January 2026, a move that has been long awaited by some members who had dropped their subscriptions due to the paywall. The change is seen as a significant step towards increasing access to scientific knowledge. However, the financial implications of this move, including the introduction of Article Processing Charges (APCs), are still being discussed. The ACM's archive of past publications will also be made available, although the extent of this is not entirely clear.
