摘要：This study aimed to measure the impact of digital heritage collections by analysing the citationsreceived in scholarly outputs. Google Scholar was used to retrieve the scholarly outputs citingMemòria Digital de Catalunya (MDC), a cooperative, open-access repository containing digitizedcollections related to Catalonia and its heritage. The number of documents citing MDC has grownsteadily since the creation of the repository in 2006. Most citing documents are scholarly outputs inthe form of articles, proceedings and monographs, and academic theses and dissertations. Citingdocuments mainly pertain to the humanities and the social sciences and are in local languages. Themost cited MDC collection contains digitized ancient Catalan periodicals. The study shows thatGoogle Scholar is a suitable tool for providing evidence of the scholarly impact of digital heritagecollections. Google Scholar indexes the full-text of documents, facilitating the retrieval of citationsinserted in the text or in sections that are not the final list of references.
