Given that it will likely be difficult to visit archives and libraries for some time due to the Covid-19 pandemic, Professor Daniel Todman of Queen Mary, University of London has started a crowd-sourced list of open access primary sources related to the Second World War. There are already more than 150 as of 30 March! An amazing resource, that will be of use well beyond the current crisis. Please do pass this on to anyone who would find it useful and add any sources not currently on the list.
