The book Elliptic Marching Methods and Domain Decomposition by Patrick J. Roache was published by CRC Press in 1995. The text contains a large number of
typographical errors due to an unfortunate computer networking problem which resulted in an earlier draft version, rather than the final draft, being sent to the publisher. A list of errata is in preparation for this
web site. In the meantime, if you have any doubts about the text, please send your inquiries to the author here at email@example.com.
