The U.S. National Committee for Crystallography (USNC/Cr) of the National Academies of Sciences, Engineering, and Medicine is providing an online workshop series for students and researchers on the use, development, and maintenance of crystallographic and structural databases. CCDC is excited to present a two-day session at the event about the Cambridge Structural Database! To celebrate, we’re hosting a live AMA (ask me anything) via Twitter with the CCDC session host, Dr Jeff Lengyel, and departmental crystallographer at the University of Notre Dame, Dr Allen Oliver.
