Saraswathi Mahal Library or Tanjore Maharaja Serfoji’s Saraswathi Mahal Library is located in Thanjavur (Tanjore), Tamil Nadu, India. It is one of the oldest libraries in Asia, and has on display a rare collection of Palm leaf manuscripts and paper written in Tamil, Hindi, Telugu, Marathi, English and a few other languages indigenous to India. The collection comprises well over 60,000 volumes, though only a tiny fraction of these are on display. The library has a complete catalogue of holdings, which is being made available online. Some rare holdings can be viewed on site by prior arrangement.
If you are a tourist visiting the Thanjavur palace, try to hire a guide who can show you around. There are no signboards about the various structures and it can get confusing while navigating around the place.
