The Christian Jensen Papers are comprised of a journal Jensen kept during his journey from Christiania, Norway to the United States on the boat Dröbak. Also included are supplemental materials such as a short biography of Jensen and a list of his children with his wife Kari. All of these documents are photocopies of originals.

Jensen's journal of his trip begins on April 20, 1861, the day that he boarded the Dröbak. The ship did not depart from the harbor at Christiania until two days later on April 22. The main entries in the journal include travel details such as the wind, storms, the direction of the ship, and landmarks.  The births and deaths that occurred during the journey were also noted. Of the 14 total deaths which he reports being associated with the Dröbak, all but one of them occurred on the ship. Most of those that died were children, including all of the babies born on the ship along with many others. During the third week of the trip, the first mate of the ship also died. After arriving in Canada on July 3 and going through a period of quarantine which the journal also briefly describes, Jensen's journey continued by train from Quebec to Wisconsin. Along with the journal can be found a brief biography of Christian Jensen, as well as a detailed list of his travel expenses from Norway to where his sister Kjersti Larson lived in Mud Branch, Wisconsin.

Following the journal is a detailed list of the children who were born to Christian and Kari Jensen. This list names each of their ten children and, where applicable, also lists significant nicknames and married names. Also on this list are the years of birth and death for each child, and their age at the time of their death.

Also included are notes on the translation of the journal. The journal was translated from the Hadeland dialect of Norwegian by two of his grandchildren in 1971. This document goes on to describe the physical dimensions and appearance of the original journal.

The last item to be found in the collection is a photocopy of an old family photograph.
