or in part. LCA Commons Hosted by the National Agricultural Library, the U.S. Life Cycle Assessment Commons (LCA Commons) is a collaboration among federal agencies, private industry, and academic researchers. The intention of LCA Commons is to aggregate and archive life cycle inventory data that represent US economic activities, making it freely available for re-use. It is geared for use in LCAs, supporting policy assessment, decision-making in technology implementation, and public disclosure of comparative product or technology assertions. i5K Workspace @ NAL The i5k Workspace@NAL provides genome projects resulting from the i5k initiative with a space to display and share genome assemblies and gene models. In particular, the Workspace is geared towards research groups that do not have the resources to display the genome assembly and its features. AGRICOLA NAL maintains AGRICOLA (AGRICultural OnLine Access), the largest bibliographic database of agricultural literature in the world. It contains more than 4.1 million records for publications dating as far back as the 15th century. 78 percent of the records are for journal articles and book chapters, while 22 percent cover full-length books, journals, maps, electronic resources, and audiovisual materials. The database indexes publications from many disciplines related to agriculture, including veterinary sciences, entomology, forestry, aquaculture and fisheries, economics, food and human nutrition, and environmental sciences. AGRICOLA originated in 1942 as the Bibliography of Agriculture, a printed index of article citation records. It was first digitized in 1970, when records were placed on magnetic tapes rather than reproducing them manually. The name was changed to AGRICOLA at this time, and the records were made available through database vendors such as Dialog and OCLC. In 1998, it became available to the general public for free on the World Wide Web. National Agricultural Library Special Collections The library's Special Collections houses rare materials related to the history of agriculture, including books, manuscripts, paintings and drawings, seed catalogs, agricultural photographs, and posters from the 1500s to the present. The subjects covered include horticulture, entomology, poultry sciences, and natural history. Pomological Watercolor Collection Within the Special Collections, the Pomological Watercolor Collection holds over 7,500 original watercolors on botanical subjects created by USDA artists between 1886 and 1942, almost half of which are apples. It is a unique resource documenting new introductions of fruit and nut cultivars as well as specimens discovered by USDA's plant explorers, representing 38 plant families in all. Some of these watercolors were published
