Over one hundred presentations from the 35th annual Charleston Library Conference (held November 4-7, 2015) are included in this annual proceedings volume. Major themes of the meeting included streaming video, analysis and assessment, demand-driven acquisition, the future of university presses, and open access publishing. While the Charleston meeting remains a core one for acquisitions librarians in dialog with publishers and vendors, the breadth of coverage of this volume reflects the fact that this conference is now one of the major venues for leaders in the publishing and library communities to shape strategy and prepare for the future. Almost 1,800 delegates attended the 2015 meeting, ranging from the staff of small public library systems to the CEOs of major corporations. This fully indexed, copyedited volume provides a rich source for the latest evidence-based research and lessons from practice in a range of information science fields. The contributors are leaders in the library, publishing, and vendor communities.
