Using air conditioner and dehumidifier to protect rare book collection

Over the years, I have put together a very large collection of rare books.  I buy books whenever I travel, and search for rare editions at antique sales, flea markets, and estate sales.  Many of the volumes I’ve collected are quite valuable.  These rare editions often have leather bindings and vellum pages, and are extremely delicate.  Although I enjoy having them on display, I want to protect them from damage.  An excess of moisture can be a big problem.  Humidity degrades the leather and bindings, and can quickly lead to mold and mildew growth.  Since I live in a part of the country that experiences hot, humid weather for the majority of the year, air conditioning is a necessity.  While the air conditioner manages temperature control, it was not designed to handle excess moisture.  Simply lowering the thermostat makes the air cooler but does not regulate humidity levels.  I have therefore invested in a dehumidifier that works in tandem with the air conditioner.  The dehumidifier maintains ideal humidity levels by extracting moisture from the air.  This not only protects the condition of my book collection but allows me to set the thermostat a bit higher without sacrificing comfort.    Lessening the workload of the air conditioner saves money on my monthly energy bills and reduces the chance of malfunction.  The dehumidifier operates silently, requires little maintenance, and creates a much healthier and enjoyable indoor environment.   Since things like dust mites and centipedes thrive in hot and humid environments, having the air conditioner and dehumidifier running gives me peace of mind.
