This bibliography is divided into three sections: spatial theory in general, digital mapping in particular, and practical tutorials. Only texts that are freely available to all online are listed here; I will not list anything behind a paywall or in a limited-access archive. Note that some of these texts will be under restrictive copyright conditions, forbidding sharing, so check the small print before being a good neighbour.
