The Library of Congress houses more than 164 million items in various formats, languages, and subjects. Found among its treasures are the international collections. The Library's four area studies divisions—African and Middle Eastern (AMED), Asian, European, and Hispanic—reading rooms provide access to many of these resources. In 2016, the four area studies divisions launched a collaborative social media program to encourage the use of the library's international collections by domestic and global online audiences. The program adopted the 4 Corners of the World blog and the Library of Congress International Collections Facebook page as interactive social media tools. This chapter will examine the interdivisional initiative through its purpose, target audience, content focus, platform selection, management and operation, audience interaction, and current status. Next, the chapter will discuss challenges and opportunities facing the four divisions. Finally, the chapter will offer recommendations for other libraries that are interested in establishing a similar program.
