赫希指数正在成为衡量个人研究成就的标准。个人措施的汇总也是机构或国家一级全球措施的基础。为了研究h指数是否可以通过其他引用记录来源可靠地计算，我们使用Web of Science （WoS）、PsycINFO和谷歌Scholar （GS）收集了四位西班牙心理学家的已知出版物的引用记录。与WoS相比，PsycINFO包含的出版记录百分比更高，而GS在这方面优于WoS和PsycINFO。与WoS相比，PsycINFO在心理学的特定领域检索了更多的引文，但在接近统计学或神经科学的领域检索了较少的引文，而GS在所有情况下检索了最多的引文。错误引用在Wos中很少（0.3%），在PsycINFO中更为普遍（1.1%），在GS中压倒性（16.5%）。所有平台都检索到唯一的引用，其中最大的一组来自GS。WoS和PsycINFO对不同心理学领域的覆盖不均匀，因此对不同领域的研究采用不同的h指数处罚。获得公平准确的h指数需要三个平台检索到的引文的联合。
Hirsch's h index is becoming the standard measure of an individual's research accomplishments. The aggregation of individuals' measures is also the basis for global measures at institutional or national levels. To investigate whether the h index can be reliably computed through alternative sources of citation records, the Web of Science (WoS), PsycINFO and Google Scholar (GS) were used to collect citation records for known publications of four Spanish psychologists. Compared with WoS, PsycINFO included a larger percentage of publication records, whereas GS outperformed WoS and PsycINFO in this respect. Compared with WoS, PsycINFO retrieved a larger number of citations in unique areas of psychology, but it retrieved a smaller number of citations in areas that are close to statistics or the neurosciences, whereas GS retrieved the largest numbers of citations in all cases. Incorrect citations were scarce in Wos (0.3%), more prevalent in PsycINFO (1.1%), and overwhelming in GS (16.5%). All platforms retrieved unique citations, the largest set coming from GS. WoS and PsycINFO cover distinct areas of psychology unevenly, thus applying different penalties on the h index of researches working in different fields. Obtaining fair and accurate h indices required the union of citations retrieved by all three platforms.
