           |  This issue of Computers in Libraries is dedicated to Celeste Peterson-Sloss (1967–2020), who, as the longtime editor of our Departments, served this publication with diligence and perseverance, while simultaneously battling a debilitating illness for the last decade. We will miss her indomitable spirit and take inspiration from her devotion.   Dick Kaser, Executive Editor  |
