Redundancies in program source code - software clones - are a common phenomenon. Although it is often claimed that software clones decrease the maintainability

Software systems contain redundant code that originated from the use of copy and paste. While such cloning may be beneficial in the short term as it accelerates

Code clones are duplicated code fragments that are copied to re-use functionality and speed up development. However, due to the duplicate nature of code clones,

This is the first book organized around code clone analysis. To cover the broad studies of code clone analysis, this book selects past research results that are

Software clones are often a result of copying and pasting as an act of ad hoc reuse by programmers, and can occur at many levels, from simple statement sequence
