 A concordance to the ASPR was published in 1978.The Old English texts in the ASPR were digitised by Greg Hidley under the auspices of the Toronto "Dictionary of Old English" project; this text was then corrected by Duncan Macrae-Gibson, though still with a few divergences from the ASPR text.Scholars waver, when citing the ASPR, over whether they regard it as six works in a numbered series or as a single work in six volumes.
