Disentangling the sequence of the notebooks can be challenging, even for readers conversant in German. Bill Cahill provides the following chronological sequencing, by volume: 17, 16, 3, 4, 8, 21, 5, 24, 19, 22, 17, 24, 20, 12, 18, 19, 14, 16, 24, 1, 15, 2, 9, 10, 11, 23, 13, 24, 7, 6. Note that some volumes contain overlapping entries.

The Henry Muhlenberg journals encompass 24 volumes that span nearly four decades of the early national period (1777-1815). These volumes offer a near-daily record of botanical descriptions as well as various lists, biblical notations, prescriptions, and questions asked of candidates for the Lutheran ministry. The journals are written in German and Latin, though Muhlenberg transcribes some quotations and place names in English. These volumes will interest German-reading scholars researching Muhlenberg, the religious practices of Lutheran ministers, and the study of botany in the early republic.
