Gender equity remains a challenge both globally and within academia, despite recent efforts to change it. Moreover, beyond the authors’ productivity, studies have reported that women often achieve lower scientific impact than their peers. To shed light on this complex relationship between the scientific impact and the themes addressed, this study conducts a comprehensive analysis of Library and Information Science field from 2007 to 2022 in four consecutive slides, identifying the principal themes covered in the field, analyzing the relative gender contribution rate, employing strategic diagrams, and assessing impact metrics, such as mean normalized citation score, 1% of most cited papers, and H-Classic. We employed science mapping analysis to explore a core of 45,650 documents from the Web of Science, with gender identification in 94.25% of cases. Our findings revealed a slight increase in the percentage of women authors within the field across the time, and a decline during the COVID-19 pandemic, demonstrating consistency in the themes addressed over the years. Women were overrepresented in the classic themes of LIS, human, and health-related fields, with these themes displaying lower performance rates. In contrast, men authors were overrepresented in STEM-related fields and innovation themes, associated with higher metric values. Our findings underlined the potential association between research themes and scientific performance, and provide societal and structural explanations for these observations. This study contributes valuable insights into the relationship between research themes and the scientific impact achieved by researchers in LIS, highlighting the importance of encouraging women’s participation in diverse knowledge domains and challenging prevailing stereotypes within academic and professional spheres.

尽管最近努力改变性别平等，但性别平等在全球和学术界仍然是一个挑战。此外，研究表明，除了作者的生产力之外，女性所取得的科学影响力往往低于同龄人。为了阐明科学影响与所讨论主题之间的复杂关系，本研究用连续四张幻灯片对 2007 年至 2022 年图书馆与信息科学领域进行了全面分析，确定了该领域涵盖的主要主题，分析了相对性别贡献率，采用战略图表，并评估影响力指标，例如平均标准化引用分数、被引用次数最多的论文的 1% 和 H-Classic。我们采用科学图谱分析来探索 Web of Science 的 45,650 份核心文档，其中 94.25% 的案例进行了性别识别。我们的研究结果显示，该领域内女性作者的比例在一段时间内略有增加，而在 COVID-19 大流行期间有所下降，这表明多年来所讨论的主题是一致的。女性在 LIS、人类和健康相关领域的经典主题中所占比例过高，这些主题的表现率较低。相比之下，男性作者在 STEM 相关领域和创新主题中所占比例过高，这与较高的指标值相关。我们的研究结果强调了研究主题与科学表现之间的潜在关联，并为这些观察结果提供了社会和结构解释。这项研究对研究主题与 LIS 研究人员所取得的科学影响之间的关系提供了宝贵的见解，强调了鼓励妇女参与不同知识领域并挑战学术和专业领域普遍存在的陈规定型观念的重要性。
