mun verða hægt að kanna áreiðanleika númer á vélvirkan hátt. Flestir stærstu útgefendur landsins eru aðilar að Al- þjóðlega bóknúmerakerfinu. Sama þróun á sér stað hér og annars staðar, að áhugi bókaútgefenda og bóksala hefur vaknað á vélvirku sölu- og birgðabókhaldi. I framtíðinni er líklegt að aukin vélvæðing á íslenska bókamarkaðinum muni leiða til þess að Alþjóðlega bóknúmerakerfið nái meiri útbreiðslu hér á landi.

SUMMARY ISBN - the international book numbering system An analysis of ISBN on the levels of composition, application and system management is presented. The author briefly traces the history of the idea which has led to the establishment of the In- ternational ISBN Agency. The composition and use of single num- bers are analyzed and demonstrated with examples. Management of ISBN is conducted through the three-tier system of international, area and publisher responsibility, each with its well defined roles and tasks. The article also describes the events which led to the establish- ment of the Icelandic National ISBN Office, its current number distribution scheme and future plans for automated control proce- dures. w w HÆSTARETTARDOMAR Hjá dómverði Hæstaréttar fást eftirtaldir árgangar: 1920-1924 500 kr. 1969 500 kr. 1925-29A 500 kr. 1970 500 kr. 1925-29B 500 kr. 1971 500 kr. 1930 500 kr. 1972 500 kr. 1931-1932 500 kr. 1973 500 kr. 1933 500 kr. 1974 500 kr. 1934 500 kr. 1975 500 kr. 1935 500 kr. 1976 500 kr. 1936 500 kr. 1977 500 kr. 1937 500 kr. 1978 500 kr. 1938 500 kr. 1979 500 kr. 1939 500 kr. 1980 700 kr. 1940 500 kr. 1981 800 kr. 1941 500 kr. 1982 900 kr. 1942 500 kr. 1983 1.000 kr. 1943 500 kr. 1984 1.200 kr. 1944 500 kr. 1985 1.400 kr. 1945 500 kr. 1986 1.800 kr. 1946 Ijóspr. 500 kr. 1987 2.400 kr. 1966 500 kr. 1988 3.000 kr. 1967 500 kr. 1989 3.600 kr. 1968 500 kr. 1990 4.500 kr. n/tw 1 IKC 1 1 UKj afgreiðslutímiþriojudagaogfimmtudagakl. 13-15, sími 18935 46
