Natural science covers general aspects including interdisciplinary works.
Astronomy covers celestial mechanics, chronology and measurement techniques, nautical almanacs and th e study of specific planets and other celestial bodies. Physics is concerned with optics, sound, mechanics, nuclear physics, electricity, light, heat and natural laws and processes, while Metrology is the science of weights and measures. The Library has a good collection of older, specialist journals but non-specialist serial titles are now emphasised. In Physics the older parts of the Collection concentrate on pure Physics while later collecting focuses on applied aspects. There is also a greater emphasis on textbooks in this area than in other disciplines since this category of publication frequ ently provides the information sought by readers.
