Many individuals helped create this memorable volume. Tim Clifford, our production editor at ALA Production Services, is responsible for the great cover graphic commemorating the journal's fiftieth anniversary. The members of the RUSQ Editorial Advisory Board helped authors to create their best work by offering thoughtful and constructive feedback. The following individuals served in this role this past year: Judith M. Arnold, Gwen Arthur, Sian Brannon, Corinne Hill, Jessica E. Moyer, Judith M. Nixon, Lisa O'Connor, Amber A. Prentiss, Michael Stephens, and Molly Strothmann. Many other experts volunteered their time to serve as occasional reviewers of manuscripts. I am grateful to the following individuals who served as referees on an as needed basis: Rebecca Albitz, Karen Antell, Christine Avery, Anne Behler, Susan Burke, Joe Fennewald, Jennifer Gilley, Russell A. Hall, Roma Harris, Daniel Hickey, Neil Hollands, Nancy Huling, Heidi Jacobs, M. Kathleen Kern, Robert H. Kieft, Robert Labaree, Dale McNeill, Tina Neville, Eric Novotny, Bonnie Osif, John Riddle, Emily Rimland, Diana Shonrock, Carol Singer, Karen Sobel, Kathleen Sullivan, Barry Trott, Dave Tyckoson, and Neal Wyatt. In addition to this collection of outstanding peer-reviewed feature articles, this volume featured the familiar columns that are beloved by many RUSQ readers. I am fortunate to work with this team of creative column editors: M. Kathleen Kern (The Accidental Technologist), Neal Wyatt (The Alert Collector), Lisa O'Connor (Information Literacy and Instruction), Marianne Ryan (Management), and Barry Trott (Readers' Advisory). Barry Trott did double duty this year as he served as RUSA President, contributing the occasional presidential column as well as serving as an ex officio member of the editorial advisory board. Tammy J. Eschedor Voelker and Karen Antell continued their excellent work as section editors of Sources. Many individuals have reviewed reference books and professional materials this past year. The result is a body of substantive, comparative, and analytical reviews that help readers make wise collection decisions during this period of tight budgets. While I would like to thank all of the book reviewers for their important work, I would like to recognize a special group of reviewers. Tammy Voelker, editor of the reference books section of Sources, has informed me that the following reviewers have reached the milestone of contributing ten reviews of reference books since volume 40: Suzanne Larsen, Evan M. Davis, and Bernadette A. Lear. Karen Antell, editor of the professional materials section, has asked me to acknowledge these distinguished reviewers of professional materials: Jenny Foster Steins, Larry Cooperman, Sarah Hart, Katy Herrick, Lisa Powell Williams, Melanie Wachsmann, Margie Ruppel, Rachel Vacek, and Mike Matthews. While this volume marks an important anniversary, it also marks an important change. Volume 50 will be the last issue to be published in traditional print format. Beginning with Volume 51, Number 1 (Fall 2011), the journal will only be published in a digital format. I served as the chair of a taskforce that spent more than a year exploring the migration of RUSQ from a print to a professionally designed electronic version. The other members of the taskforce were Judith M. Arnold, Gwen Arthur, Bobray Bordelon, and Neal Wyatt. After carefully examining many factors (cost implications, possible impact on advertising, access, archival issues, potential impact on the journal's scholarly reputation, and membership satisfaction), the taskforce recommended that the print version of RUSQ be abandoned and that we move to an all-electronic version. This recommendation was accepted by the RUSA Board at the 2011 ALA Midwinter Meeting. The taskforce believes that the time is right to make this change. RUSQ has an established reputation and we are confident that the move to a digital format won't impact the journal's reputation. …
