This study links Translator Studies with Library and Information Studies in order to identify methodological and practical problems. By using the example of the Spanish National Library, the authors show that data on translators are not consistently recorded in bibliographic resources and are therefore more difficult to access. Based on this critical survey, a new methodological approach is developed, which builds on a corpus of all German-Spanish translations from 1970 to 2010. This approach makes it possible to use bibliographic catalogues as a means of raising awareness in society of the role of translators as knowledge generators.
