Building material from the main stacks of Orton Library was sampled and analyzed for the presence of asbestos minerals. Electron
microprobe analysis, X-ray diffraction, and optical microscopy were used to identify minerals in the project samples. Only one of the six known asbestos minerals was found in the building material. Chrysotile was
identified in the samples by the optical microscopy method. No estimates regarding the relative percentages of asbestos in the project samples were made
