"Anderson provides a comprehensive summary and review of the mathematical theory of cosmic strings. The subject is not in a state of rapid change so the book is up to date and it is likely to remain so for some time. Although the book is technical and requires a strong mathematical background and an interest in differential geometry, it is well written and reads easily … I found the later sections particularly interesting, especially the discussion of the infinite straight string and the associated singularity structure … This is a valuable reference work and compendium of results."-D.R.
