In, “The Post-Marc Era,” Roy Tennant expands upon his critique of MARC from, “MARC Must Die.” In part 1, Tennant writes in a very inspiring tone. He emphasizes that “the revolution will be live.” In part 2, he takes a more practical approach when he discusses the inconsistencies in MARC data by using the 264 field as an example. However, this left me thinking about authority control. This piece, arguably, speaks to the lack of universality for libraries, in general. I think the question of universal authority control is every looming, but an extremely pertinent one.
