Littleton Seed Library is a project of Littleton Community Farm. Seeds come from volunteers who save seeds and from donations from seed companies.

The seed library is normally available in the spring in a repurposed card catalog in the Reuben Hoar Library in Littleton. In 2020, the library had to close due to the Covid-19 situation so the seed library went virtual with online ordering and a social distancing adherent set of drive-thru pickup opportunities.
