This study aimed to measure the impact of digital heritage collections by analysing the citations received in scholarly outputs. Google Scholar was used to retrieve the scholarly outputs citing Memòria Digital de Catalunya (MDC), a cooperative, open-access repository containing digitized collections related to Catalonia and its heritage. The number of documents citing MDC has grown steadily since the creation of the repository in 2006. Most citing documents are scholarly outputs in the form of articles, proceedings and monographs, and academic theses and dissertations. Citing documents mainly pertain to the humanities and the social sciences and are in local languages. The most cited MDC collection contains digitized ancient Catalan periodicals. The study shows that Google Scholar is a suitable tool for providing evidence of the scholarly impact of digital heritage collections. Google Scholar indexes the full-text of documents, facilitating the retrieval of citations inserted in the text or in sections that are not the final list of references. It also indexes document types, such as theses and dissertations, which contain a significant share of the citations to digital heritage collections.

使用Google学术搜索评估数字遗产收藏的影响

这项研究旨在通过分析学术成果中的引用来衡量数字遗产收藏的影响。Google Scholar被用来检索加泰罗尼亚数字记忆博物馆（MDC）的学术成果，该博物馆是一个合作的，开放获取的存储库，其中包含与加泰罗尼亚及其遗产相关的数字化馆藏。自2006年建立知识库以来，引用MDC的文献数量一直在稳定增长。大多数引用文献都是文章，论文和专着以及学术论文和论文形式的学术成果。引用文件主要涉及人文科学和社会科学，并使用当地语言。引用最多的MDC集合包含数字化的古代加泰罗尼亚语期刊。研究表明，Google学术搜索是提供数字遗产收藏的学术影响证据的合适工具。Google学术搜索会为文档的全文索引，从而便于检索文本或非最终参考列表部分中插入的引文。它还对诸如论文和学位论文之类的文档类型进行索引，其中包含了对数字遗产收藏的大量引用。
