This is an overview of Bailey chains, an important tool in the discovery and proof of \(q\)-series identities. The author gives examples of one- and multi-dimensional Bailey chains as well as a recent variation he calls the \(WP\)-Bailey chain because it is based on Bailey’s proof of an identity between two very well-poised basic hypergeometric series.
