How to enter a book that contains 2 complementary documents, and shows up that way in Library of Congress??

I just added Faith on the Frontier to my library using the iPhone app, which picked up the Library of Congress entry ( https://lccn.loc.gov/77152426 ). The title field in the resulting LT record was populated with the following text:
Faith on the frontier : religion in Colorado before August 1876

The cover of my book has just "Faith on the Frontier" written on it. However, the title page AND the LoC entry reflect the fact that the physical book has 2 distinct documents put together by 2 distinct people. The second document constitutes about 1/4 of the total work. Here are the first 3 segments of the LoC entry, with a little bit of spacing added to clarify the 2 listed contributors, each of which is its entirety connected to an LoC link:

Book
Faith on the frontier : religion in Colorado before August 1876 / edited by Louisa Ward Arps. Religion in Colorado : a bibliography / compiled by Harold M. Parker, Jr.
Contributors:
Arps, Louisa Ward, 1901-
Parker, Harold M. Religion in Colorado. 1976

Published: Colorado Council of Churches, Denver, 1976

Q: Is there a good way to get both those titles into the LT "Title" field?

Title:
Faith on the frontier : religion in Colorado before August 1876 AND Religion in Colorado : a bibliography
