< >In a networked and globalized world of information the form of national bibliographies may have changed, however their major function remains unchanged: to inform about a country's publication landscape, its cultural and intellectual heritage. Subject access offers a major route into this landscape providing information about the dispersion of publications in specific fields of knowledge and topics contained in a particular national publishing output.The Guidelines for Subject Access in National Bibliographies give graded recommendations concerning subject indexing policies for national bibliographic agencies and illustrating various policies by providing best practice examples.
