The Pacific Northwest Seed and Nursery Catalog Collection consists of catalogs published by nurseries and seed companies, primarily in Oregon and Washington. The catalogs feature vegetable, herb, and flower seeds; fruit trees and vines; and perennial and native plants. The catalogs include a number of varieties (especially of tomatoes) developed by Oregon State University researchers, such as James Baggett.

Catalogs are also included from Abundant Life Seeds, Deep Diversity, Earth's Rising Nursery, Fall Creek Farm and Nursery, Forest Farm, Goodwin Creek Gardens, Greengable Farms, Irish Eyes and Garden City Seeds, Jackson and Perkins, Kalmia Farm, Nature's Garden, Northwoods Wholesale Nursery, One Green World, Oregon Exotics Rare Fruit Nursery, Peace Seeds, Raintree Nursery, Russell Graham Purveyor of Plants, Thyme Garden Herb Company, West Coast Seeds, Wild Garden Seed, and Zenner Brothers Seed Company.

The catalogs were assembled by Lawrence A. and Rebecca Landis.
