{"value"=>"<p>Copies of shipment invoices received from aid societies, USSC branches and offices. The information was entered into these volumes by Central Office staff as soon as the invoices were collected. When the actual packages arrived, their entries in these volumes were checked off. Entries provide the invoice date, the name of the sender, and the number of packages sent, with a list of their contents. Beginning with Invoice book 3 on December 17, 1863, entries are numbered consecutively and correspond to numbers in the transit books. Invoice books 3 and 4 have separate alphabetical indexes to senders by place and name.</p>"}
