We are very grateful to the following people for their contributions to Abel:

• First, to Frances Hughes and Tricia Feather, who tolerated a great deal of neglect from their husbands during the time it took to write Abel. Without their support and encouragement the job would never have been done
• The microSIRIL method library was created by Andrew Craddock and is maintained by Julian Morgan. We are very grateful to them for making the results of their work available to all
• Alex Hunt provided the digitised bell recordings that are included with Abel. We are grateful for his permission to use them
• We are grateful for the help David Bagley has given with getting Abel and his Multi-Bell Interface working together, including the use of a prototype Interface
• The picture of Audlem Church is used by kind permission of the artist, Ian Curry
• Abel is named after Abel Rudhall, who cast Audlem's six bells in 1736
