¹⁰ Another recent doctoral dissertation involving hymns in a Spanish source, ‘Das Antiphonar von Sta. Cruz de la Serós XII. Jh’, defended by Susana Zapke at the University of Hamburg in 1993, includes a study of the antiphoner, an edition and partial facsimile. The study includes a concordance table of hymns in the Sta. Cruz antiphoner, a Silos antiphoner (London, British Library, Add. 30850), the Huesca hymnary, and the CAO. Zapke is currently preparing a catalogue of manuscripts in the cathedral archive of Huesca.

¹³ The dangers of this approach will be evident to anyone who has compared the AH to its manuscript sources: the editions are all more or less riddled with errors, stemming from typography, transcription and intentional (though unacknowledged) meddling.
