The following bibliography is drawn mainly from two lists: (i) the first section of Hilda Lietzmann's ‘Bibliografie Herbert Grundmann’ and (ii) the list of Grundmann's works in the ‘Literature Database for the Middle Ages’ of the Regesta Imperii. It lists published works and articles, together with a selection of encyclopaedia articles and Grundmann's Monumenta reports. The reader should go to Lietzmann's bibliography for its selection of reviews and its fuller lists of Grundmann's short notes, commemorative pieces, Monumenta reports and encyclopaedia articles.

The numbers as well as the contents of Lietzmann's bibliography – 1–95, covering 1926–71 – are followed below. Nos. 60a and 95a denote her afterthought additions. But within the range 1–95 the other numbers followed by letters are our additions, as are also nos. 96–107.

References to Grundmann's works in this volume's Introduction and its translation of Arno Borst's memorial of Grundmann use these bibliography numbers.
