easy and speedy access to the entire collection of its forty three libraries. General (i.e. non-affiliated to the institution) digital access to UFRJ's libraries is made through the Minerva Base, a database that, much like the SiBI, gathers all university libraries into a single website. Among the most noteworthy museums and cultural spaces are: the National Museum, Latin America's largest museum and anthropological of natural history as well as Brazil's oldest scientific institution. Its building is a conversion from the Brazilian Imperial Family's old palace in "Paço de São Cristóvão" and it was founded by royal figure Dom João VI in 1818, but integrated to the university only much afterwards, in 1946. Brazil's emperor Dom Pedro II himself, an enthusiast for scientific knowledge, contributed to the museum's collection with Egyptian art, fossils, botanic species and many other items obtained by during his personal trips. Laboratories occupy a great portion of the museum and spread to some buildings raised in "Horto Botânico" (Botanic Garden), in "Quinta da Boa Vista". In Botafogo, the university also manages the "Casa da Ciência" (House of Science), a cultural center of science and technology active since 1995 and dedicated to the exploration of languages and of popular forms of communication such as theater, music and audiovisual techniques. It performs periodical workshops and expositions opened to both students and the general public.
