Naber was a self-taught historian. During the 1890s, she started publishing on important female historical figures. During her lifetime she published many biographies of noteworthy women as well as works on the early Dutch women's movement in the 19th century. Some notable works include her 1909
Wegbereidsters ('Pioneers') about various women who had paved the way for the women's movement and
Frederika Bremer (1901-1865). Naar hare brieven (1921) a biography of Swedish feminist and author
Frederika Bremer based on her letters. She furthermore braved an attempt at an overview of the Dutch Women's Movement (entitled
Eerste Proeve van een Chronologisch Overzicht van de Geschiedenis der Vrouwenbeweging in Nederland). This text later functioned as an important reference work for fellow IAV-founder Willemijn Posthumus-van der Goot's seminal overview of the Dutch women's movement since the 19th century
Van Moeder op Dochter (‘Mother to Daughter’). In 1914, Naber established
De Nederlandsche Vrouwengids (‘The Dutch Women’s Guide’) to address women's issues and concerns. The
Guide ran until 1919. In 1918, she became the first female board member of the prestigious
Maatschappij der Nederlandse Letterkunde or Society of Dutch Literature. In 1935 she collaborated with Dutch feminists
Willemijn Posthumus-van der Goot and
Rosa Manus to establish the
International Archives for the Women's Movement (IAV), now known as
Atria Institute on gender equality and women's history. ==Politics and later life==
