A linearly ordered set \(G\) equipped by the structure of a (multiplicative) group is said to be a right-ordered group if the right multiplication in the group \(G\) preserves the order defined on \(G\). Regarded as abstract groups, the right-ordered groups are exactly the automorphism groups of linearly ordered sets. The book under review gives a comprehensive account of the current state of the theory of right-ordered groups.
