Dansk Biografisk Leksikon

Dansk Biografisk Leksikon (usually abbreviated DBL; title of first edition written Dansk biografisk Lexikon) is a Danish biographical dictionary that has been published in three editions. The first edition, Dansk biografisk Lexikon, tillige omfattende Norge for tidsrummet 1537-1814 ("...including Norway for the period 1537-1814") was published in nineteen volumes 1887-1905 under the editorship of the historian Carl Frederik Bricka. The first edition, which is in the public domain is available online at Projekt Runeberg.

Later editions were published 1933-1934 (27 volumes) and 1979-1984 (16 volumes). While some of the biographies from the previous editions have been updated in the third edition, many others – considered of less contemporary relevance – were left out and need to be consulted in its predecessors.
