The Smithsonian Institution Libraries (SIL) is a distributed network of 20 libraries that serves researchers, scholars, curators and the general public. SIL has over 1.5 million volumes, 4,522 print journal subscriptions, and 3,000 electronic journals. It provides resources and research assistance to support the work of the Smithsonian. SIL faces challenges of rising costs for print journals and increasing demand for electronic resources.
