NLS is an acronym for National Library Service, the network of Italian libraries promoted by the Ministry of Cultural Heritage and Activity, the Regional Authorities, and universities. It is coordinated by the Central Institute for the Unique Catalogue. Thousands of public libraries take part: local libraries, universities, public and private institutes in various subject fields.

Each library in the NLS network has made available its own catalogue, thus allowing the largest national catalogue.
