National Science Library, National library in Ottawa, Canada
The National Science Library is Canada's national library for science and technology, located in building M-55 on Montreal Road in Ottawa. It holds a large collection of books, journals, and research materials focused on natural and applied sciences.
The library was founded in 1924 and received its official status as Canada's national science library in 1966 through a federal decision. That recognition came at a time when scientific research across Canada was growing rapidly and needed a dedicated national resource.
The library serves researchers, scientists, and professionals from across Canada as a working resource rather than a general public space. Visitors notice that the reading areas are set up for focused study, with materials oriented toward science and technology fields.
Access is restricted to weekdays and requires prior approval along with valid identification at the entrance. The library is set up for professional and research use, so it is worth confirming your eligibility before making the trip.
The library holds a digitized collection of around 12,000 historical photographs documenting scientific developments across Canada over many decades. This visual archive sits alongside the printed collection and is something many visitors do not expect to find there.
