Great news! The online index and reviewing service, ZbMath, is to become open access from the start of 2021. This will be of great benefit to mathematicians in developing countries, and we applaud the team at ZbMath for making this happen.
If, in the meantime, mathematicians from developing countries would like to access ZbMath, then this is possible. Details of how to make this happen are here.
More information on the move to open access is available here.
