This article demonstrates some of the possibilities of the structured database, National Biographical Dictionary of Swedish Women (Svenskt Kvinnobiografiskt Lexikon, www.skbl.se, hereafter SKBL) for research in women's and gender history. SKBL is a digitally published biographical dictionary of articles with data on 2,000 Swedish women living from the Middle Ages to the present, published in both Swedish and English. The article examines how the Dictionary aims to make visible the contributions of women, often overlooked previously, with emphasis on their contributions to societal development. However, both interface and tagging entail classifications that are governed by principles decided in accordance with present-centred values and technological and cataloguing systems. These principles enable certain advanced searches in SKBL on historical social conditions, demonstrated here by a discussion of the group, 'pioneers'. Despite all the difficulties and obvious limitations of SKBL, this article argues that the project of making visible women's contributions in the past continues to remain necessary.The growth of the fields of women's and gender studies since the 1970s has re-orientated Swedish historiography. A superficial measure of the change is the ever-growing number of doctoral theses published in these areas. The database GENA, produced by the University Library in Gothenburg in collaboration with the Swedish Secretariat for Gender Research, lists published doctoral theses in the scholarly field of 'women and gender studies' in all disciplines at all universities in Sweden. A search for doctoral theses in History for the time period 1960-2020 illuminates the increasing scholarly interest: in the 1960s there was only one, in the 1970s there were three, in the 1980s there were ten, and by 2020 the total was 153. 1 In 2018, 10 doctoral theses were produced in the fields of gender and women's history.In this context of the evidence of expanding research on women subjects (as well as men), and gender history topics, one might ask why a national biographical Dictionary of Swedish-born women is still seen as necessary? In this article, I argue that despite expansive research on women's and gender history by scholars of Swedish history, the
