This collection of 12 essays on bibliographic services in Australia has been published as part of the National Library of Australia's effort to encourage a voluntary national information system. An introduction and overview of bibliography in Australia are followed by brief surveys of the major desiderata for Australian subject bibliography in literature (A. Lawson), children's books and materials (J. D. Adams), music (K. Horn), politics (J. Rydon), wildlife (M. C. Downes), legal writings (E. K. Braybrooke), economics (F. G. Davidson), educatiin (J. Thawley), agriculture (H. M. Russell and G. Levick), geography (R. G. Freestone), and non-Australian history materials located in Australian libraries (R. J. Shultz and Janet F. Schultz). Each essay is contributed by a subject specialist and contains a review of current bibliographic sources available and recommendations for improvement in bibliographic information in that subject area. Among a wide range of suggestions are included the inauguration or strengthening of national information clearinghouses, union lists of sources, or national bibliographies; the updating of previously existing subject bibliographies; the creation of new periodical indexes; the computerization of data; the full utilization of international bibliographical machinery for Australian material; and the improvement of book indexing. References are provided for each subject essay. (ESR)
