Cirm’s library owns one of the richest collections of mathematics books in France. With over 35,000 books and periodicals and 1,500 paper or electronic journals, all areas of pure and applied mathematics are represented. Readers can on average find 500 new acquisitions each year to keep up to date with the latest printed material. In addition, Cirm’s library has its own unique treasures: a large collection of complete works, some material dating back to the 16th century right to the start of the 19th century, and a Russian collection of books on mathematics. Personal donations from illustrious mathematicians such as Gaston Julia, Szolem Mandelbrojt, André Adler, Philippe Flajeolet and Jean-Louis Ovaert have extended this rich collection.
