What type of reference materials does HarperCollins Christian Publishing produce?

Zondervan publishes the following reference materials:

A Bible Handbook is a companion to Bible reading. It’s arranged in the order of the books of the Bible. It provides background before you read through a Bible book, offers commentary and illustrations as you read, and presents topical and historical notes to expand your understanding.

A Concordance lists common words found in the Bible and shows the places they occur. For example, under the entry ‘faith’ you’d find the locations in the Bible where the word ‘faith’ is used. A Concordance enables you to do word studies as well as locate verses you vaguely remember.

A Topical Bible includes a guide to different subjects addressed in the Bible. Under faith, it will list not only the most important verses where the word ‘faith’ is found, but also verses that talk about faith without using the word, for example Genesis 15:6, ‘Abram believed the LORD. . . .’

A Bible Dictionary gives more detailed information about people, places, words, and events in the Bible. You could use it to learn more about what the Bible says about children, Peter, Egypt, or miracles.

A Bible Commentary is a single or multi-volume work that explains the meaning of Bible passages.

A Bible Dictionary provides definitions of Biblical words as
well as the Hebrew/Greek equivalent of those words found in scripture.

A Bible Atlas contains maps and charts of the Biblical world
and its geography, generally compared with the geography of the modern world.
