AACR2, MARC21 and RDA

AACR2

AACR description:

AACR2 rules based on IFLA principles

Based on information in the item, form the title page
Use of outside information such as, dates of author's birth and death; to check the real name of an author using a pen name

AACR2 rules aim at describing documents: succinctly, accurately and consistently, though they are detailed and complex.

Three 'levels of description' allowed
Differ according to how much information is included
First level: Simplest, for small libraries
Second level: intermediate, for most libraries
Third level: complex, for national and research libraries - heavily detailed

First level description includes at least these elements:
# Title
# Statement of responsibility
# Edition
# Type of publication
# Publishing details
# Extent of item
# Notes
# Standard number

MARC21:

RDA:
