i Editor’s Introduction IT IS MY PLEASURE AND PRIVILEGE to present to you the seventy- fifth installment of the Summary of Proceedings, the official record of Atla’s annual conference. Most authorities attest that the seventy- fifth is the diamond anniversary, although confusingly the same title is also applied to the sixtieth. In any case, Atla Annual 2021 was a diamond-worthy jubilee, abounding in content demonstrative of a firm and lustrous commitment to the highest values of our profes- sion. Gathered here in the Proceedings are the fruits of nearly three dozen papers, conversation groups, panel discussions, listen-and- learn sessions, and other offerings for your edification. Owing to the persistence of the pandemic, attendees were obliged to convene exclusively online for a second consecutive year. Indeed, COVID-19 made its mark throughout the program, occasion- ing numerous presentations on the ways in which librarians have adapted their services to the exigencies of this time of salubrious social separation. Topics such as remote instruction, open access, and controlled digital lending would have been of trending interest in any case, but the COVID crisis lent them an urgency none could likely have foreseen before March 2020. Also of surpassing urgency and prominence was the fourfold issue of diversity, equity, inclusion, and accessibility (DEIA). Reflect- ing the association’s recent push to foster constructive action around this timely concern, many of our colleagues offered practical advice in such areas as implementing antiracism in cataloging, closing the Wikipedia gender gap, and developing more accessible spaces and websites. Naturally, there was room for presentations on perennial library topics as well, including cataloging and classification, collection development, flourishing through a construction project, and much more. ii AT L A 202 1 PROCEEDINGS The editor’s introduction has often remarked on the charm of the host city and the high times enjoyed there among friends. This year’s virtual venue may have lacked the appeal of the towering firs of Vancouver or the waving palms of Long Beach, but it brought us together all the same. In next year’s volume, Deo volente, there will be cause to wax rhapsodic about the Mid-Atlantic grace of Charm City itself. But until then, happy reading! Derek J. Rieckens Editor-in-Chief
