This research examines the characteristics and types of bibliographic relationships in Resource Description and Access (RDA) book cataloging records produced in OCLC after RDA implementation. Data was sampled (n = 1,550), coded, and analyzed for work-to-work, expression-to-expression, and manifestation-to-manifestation relationships. Results show work-to-work bibliographic relationships are most frequently recorded in both PCC records (57.4%) and non-PCC (59.5%); expression-to-expression are recorded the least in PCC (8.3%) and non-PCC (15.8%); and manifestation-to-manifestation relationships fall between with PCC (34.4%) and non-PCC (24.7%). This study also investigates the MARC fields used to record relationships and common characteristics in cataloging records with bibliographic relationships.
