The Grass Valley Public Library (renamed the Grass Valley Library-Royce Branch) is a Carnegie library and on the National Register of Historic Places.

[2] Located in Grass Valley, California and a part of the Nevada County Library System, it is open Tuesday through Saturday.

There were several early attempts to establish a library in the California Gold Rush town of Grass Valley.

The Emmanuel Episcopal Church was established in Grass Valley in 1858,[3] but it wasn't until 1901 that the non-denominational Emmanuel Church Library opened to provide library services to "the Atheist and the Buddhist if such there be".

The builders were Welch Bros. and Hannemann from Oakland who also built the Gridley Carnegie Library.
