The Map Room

Microsoft’s SQL Server Developer Center is an unusual place for it, but there it is anyway: a primer on map projections entitled Introduction to Spatial Coordinate Systems: Flat Maps for a Round Planet. The summary: “This paper is an introduction to Earth-oriented coordinate systems, projections, models, and mapping. While not specific to any technology, this information provides valuable background for those who will use spatial data in SQL Server.” It is easily applicable outside that context as well.
