Gerald B. Folland
Concerning my book Advanced Calculus:
The new edition is identical to the old one, except that (1) the errors noted on the errata sheets for the print edition (see below) have all been corrected, and (2) a brief summary of basic logic has been appended at the very end (after the index).
This book was published by Prentice-Hall (later absorbed into Pearson Education)
from 2002 to 2022.
They have discontinued publication and returned the publication
rights to me.
A new edition of this book is now freely available in pdf form via this link:
Advanced Calculus (2nd ed.) by Gerald B. Folland
You can find lists of errata for my more recent
via the following
links (in pdf format):
Note: To find out which printing you have, look on the back of the
title page. Under the line "Printed in the United States of America"
or at the bottom of the page
there is a list of integers; the number of the printing is the smallest
integer on the list.
