This structure appears to be an addendum to the grander Legislative Assembly Building, but was constructed at the same time; four iron doors at each entrance separate this unique room from the rest of the Legislature to protect its contents from fire.
The main library room has the shape of a small Roman Basilica with a southerly apse-like bay window and butternut bookcases, creating cozy alcoves on each side of the room. The high wooden ceiling with exposed beams supports an upper row of windows.
The Legislative Library contains approximately 50,000 books, and has an excellent collection of New Brunswick materials. Of note is a complete set of original, hand-painted, copper engravings of the Birds of America by John James Audubon, painted in the 1830s – one of only five such sets in Canada.
