For 60 years now, ABC-CLIO, LLC, has been recognized as an industry leader in the creation of innovative reference and professional development resources. Their four complementary imprints publish a comprehensive range of print and online materials that benefit learners, researchers, educators, librarians, and information specialists worldwide. Their company’s distinctive name reflects its rich history in reference and educational publishing. The American Bibliographic Center (ABC) was founded in 1955 to create serial bibliographies. Soon after, CLIO Press was formed to publish historical periodicals—and ABC-CLIO was born. Clio, one of the nine Greek muses and patron goddess of history, serves as fitting inspiration for our activities, both then and now. Over the years, they've expanded their focus to include many disciplines and embrace the best of new technologies, but they've remained true to their original commitment to excellence, innovation, and meeting the needs of their customers. They're proud to be continuing the family tradition begun by Inge and Eric Boehm. Today, ABC-CLIO is owned by the Boehm and Snyder families and operates under the direction of Ron Boehm and Becky Snyder. Together, they continue to strive to produce the best materials and to support learning at all levels through innovative solutions. Libraries Unlimited is committed to supporting the life-long professional development of educators and librarians through every phase of their careers. By librarians, for librarians, Libraries Unlimited believes in cultivating a community where professionals can explore emerging directions and acquire new skills to make their library’s potential truly unlimited.
