  We present the CosmoBolognaLib, a large set of Open Source C++ numerical
libraries for cosmological calculations. CosmoBolognaLib is a living project
aimed at defining a common numerical environment for cosmological
investigations of the large-scale structure of the Universe. In particular, one
of the primary focuses of this software is to help in handling astronomical
catalogues, both real and simulated, measuring one-point, two-point and
three-point statistics in configuration space, and performing cosmological
analyses. In this paper, we discuss the main features of this software,
providing an overview of all the available C++ classes implemented up to now.
Both the CosmoBolognaLib and their associated doxygen documentation can be
freely downloaded at https://github.com/federicomarulli/CosmoBolognaLib. We
provide also some examples to explain how these libraries can be included in
either C++ or Python codes.
