RDA: a better mousetrap or an incoherent hodge-podge?

摘要

1) As I understand it RDA is a new cataloguing standard designed for the digital environment.So far as Im aware AACR2 has been able to accommodate the digital sources which we make available so wouldn"t it have been preferable to update it2? The last few decades have seen new resource types or publishing practices emerging at an increasing rate, requiring regular updating of AACR2 to include new rules for issues specific to a single resource type or publishing practice. However, there is a large common core of information needed about any resource: creator (s),title, publication details, communication type (e.g. text, image, sound, notations), medium (e.g. printed paper, digital file), size (e.g. pages, file size, running time, dimensions), subject and relationships to other resources. RDA uses a basic rule for each type of information, phrased to avoid the assumption that it refers to a specific resource type and ilustrating how itis applied in a range of resource types.
