For purposes of arrangement, the Lighthall Papers have been treated as one unit. However, for purposes of descriptions, they have been divided into two parts: the W.D. Lighthall papers and the Lighthall Family papers.

The papers of W.D. Lighthall are divided into a number of different series: an Original Series, Letters and Papers, 1881-1946, and a New Series, Letters and Papers, 1865-1954. The greater part of the correspondence is to be found in these two series.

Although more than forty members of the Lighthall and allied families are represented in the collection, only those with significant bodies of papers are mentioned here, including Cybel Wilkes Lighthall, Alice M. S. Lighthall, Anne Dean Lighthall, W. F. Lighthall, and the Reverend Dr. Henry Wilkes, among others.
