First there is http://en.wikipedia.org/wiki/William_Halsey_Wood, which I mention as an entry point for those interested in this man (and also because I wrote it). It includes a brief biography and a more extensive (though by no means complete) list of his buildings. Some of this is repeated at http://www.archiplanet.org/wiki/William_Halsey_Wood, which I also authored.
At http://www.smethporthistory.org you can learn about St. Luke's Episcopal church in that western Pennsylvania community and its architect. There is even a down-loadable brochure in pdf format.
Also, visit http://www.njchurchscape.com for an extensive treatment of religious architecture in the state of New Jersey and biographies of many architects active there, including WHW. There are individual pages for each of Wood's New Jersey churches.
Wood also plays prominently at the websites of various church congregations who have found and acknowledged his spirit in their building:
- St. Mary's Episcopal Church, Kansas City, MO (http://www.stmaryskc.org/index.php)
- St. Matthew's Cathedral, Laramie, WY (http://saintmatthews.qwestoffice.net)
- St. Michael and All Angels, Anniston, AL (http://stmaaa.org)
