Series I. Shipping Papers includes ships' papers, account books, memorandum books, accounts, and trade memoranda largely associated with Shreve's trading activities at Canton from 1813 to 1822 and has been divided into three subseries. See Appendix I for a complete listing of ships owned, mastered, and chartered by Benamin Shreve as they are represented in these papers.

Subseries A. Ships' Papers contain papers from individual ships. The most complete documentation of trade in China is found among the papers of the ship China, and the brigs Canton, Comet, Governor Endicott, and New Hazard. The papers provide detailed information on trade in silks, export china, teas, and various textiles as well as descriptions of negotiations and agreements with Hong Kong merchants. Additionally, the papers of the ship China contain documentation of a cargo of opium shipped from Salem to Canton.

Other items of interest in the ships' papers include a list of rations distributed on the US frigate Congress and a spar plan for the brig Dawn, which was named schooner Four Sons before her capture by the privateer schooner Fame in 1812. A letter from Shreve to his nephew Samuel V. Shreve contains the elder's advice on how to manage a mercantile voyage. It provides an intimate and detailed account of how ship masters and supercargoes managed sales and purchases of cargoes and how they were expected to conduct themselves in their trading activities (see ship Eliza, box 2, folder 5). The papers of brig George document a cargo of opium purchased at Malta and describe the capture of the vessel by the HMS Emulous while in route from Liverpool in 1812. Shreve's brig Washington was designed in the style of some other successful Salem vessels and the brig's papers include shipbuilding accounts and papers associated with a pepper voyage to Sumatra in 1824. The bark William Gray was lost at sea in 1811 and the ship's papers describe the incident and Shreve's subsequent claims against the Danish government in 1831.

Subseries B. Account Books, Letter books, and Memorandum Books provides additional detail on the voyages of Shreve's vessels. Some of the items in these volumes are duplicates of documents in subseries A, as Shreve often copied his letters and memoranda in triplicate. In some instances, a single volume often refers to more than one vessel. The shipping accounts are summaries of Shreve's position with a number of merchant houses, agents, and investors in Salem and abroad. The Sarah Elizabeth (Brig) account book also contains trading accounts, letters of instruction, an account of a quarrel with natives, and colored sketches of natives (box 10, folder 9).

Subseries C. Other Memoranda includes trade and miscellaneous memoranda. The trade memoranda are descriptions of trading practices at various ports that often identify appropriate cargoes for particular markets and also include lists of vessels and cargoes arriving and departing from specific ports. Among the miscellaneous trade memoranda is "A Correct Table of the Real and Imaginary Monies of the Whole World," which lists world currencies and their exchange rates. There are also notes from Henry Pickering on purchases of prints by well-known European artists.
