A *persistent data structure* is defined as a data structure that preserves the previous version of the data when the data is modified.

You might want to find another term for this -- it's very different from what "persistent data structure" usually means (i.e. something that gets saved to a file or database with some degree of automagicness).
Unfortunately this is actually the correct terminology from all existing literature! :(
