I would like to find a list of books written by Finnish authors that have been tranlated into English. I am interested in history and historical novels.

Finnish National Bibliography contains a list of all the Finnish books that have
been translated into English. This list can be narrowed down in various ways, e.g
to include only fiction, non-fiction, history etc. However, to obtain such a list
you should visit either one of the Helsinki City public libraries or else the
University Library of Helsinki. All the above mentioned libraries have the said
database available in a CD-ROM format.
