In this paper I aim to offer a state-of-the-art assessment of extant studies on qiraʾāt and tafsīr, and an overview of the development of research in Qur'anic exegesis, in al-Andalus. Over the last decade, humanities research has embraced the use of new methodologies, and different types of bio-bibliographical resources have recently become available within the field of Andalusī studies. As a result, we have at our disposal new tools that allow us to manage a larger amount of data, such as the HATA online catalogue, which will be employed to study the transmission of Andalusian exegetical knowledge in the Islamic world. Pilgrimages and studies trips (riḥlāt fī ṭalab al-ʿilm) have always been the main connection between al-Andalus and the Islamic East and, as it will be shown, certain Andalusī works are known nowadays in the contemporary Islamic world because of this medieval link. Therefore, this contribution will not only discuss the most famous tafsīr titles and authors within the Andalusian literary tradition, but also the diffusion of these Andalusian works to the Islamic East, as well as the reciprocal spread of major Arabic works into Andalusia.
