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

• First, to our families, who tolerated a great deal of neglect 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 original digitised bell recordings that are included with Abel. We are grateful for his permission to use them
• We are grateful to David Bagley for the recordings of Worcester Cathedral bells, and also for the help David gave with getting Abel and his Multi-Bell Interface working together, including the use of a prototype Interface
• Aidan Hedley provided some of the designs for sensors. We are grateful for his permission to publish them here and on the AbelSim website
• Special thanks to all the ringers who appear in the "Moving Ringers" display, and to the parents of the young ringers. In this strange age, to risk appearing in public is no small thing.
• The picture of Audlem Church is used by kind permission of the artist, the late Ian Curry
• Abel is named after Abel Rudhall, who cast Audlem's six bells in 1736
