This section covers books on marking and measuring tools. This broad category includes gages of all types, rules, and any tool that would be used for marking out a dimension on a piece of work or transferring that measurement elsewhere. For convenience, we also include tools for level determination here. This is at present just levels, but could also include plumb bobs or any similar devices in the future.
