A Textbook of Convergence

by William Leonard Ferrar.

Introduction
Convergence is the study of limiting process in mathematics. This technique is used to help determine the convergence of infinite sums (along with other places). This book takes on this topic and studies it in great detail providing challenging exercises along the way. Users unfamiliar with this book can find more information here.

As always I would be interested in hearing back if any errors are found to exist.
