This series contains invoices to the Long Store from other companies, showing that orders were paid for in full. Specific company invoices include: Harrisonburg Grocery Co. Inc. Exclusively Wholesale; Merchants Grocery and Hardware Co. (successors of Snell Grocery and Hardware Co.); Sears, Roebuck and Co.; Coca-Cola Co.; National Biscuit Co. (Nabisco); and the Standard Oil Co.

Companies also sent advertisements to the Long Store in order to try to persuade the store to buy their products. Specific company and agency advertisements include advertisements from the US Food Administration; Mishawaka Rubber and Woolen Mfg. Co.; Sears, Roebuck and Co.; and the Merchants Grocery and Hardware Co.

Correspondence includes letters and envelopes addressed to the Long Store from a variety of companies. Most of the correspondence thanks the Long Store for their business, provides information about backorders, includes contract letters, and personal correspondence. Companies that sent correspondence letters include: Miller & Yager General Commission Merchants, Superior Dairy Goods Moseley & Stoddard MFG Co., Darby Manufacturing Co., and R. P. Bayley & Co Importers of China & Glass.

All of these papers provide insight into the business transactions of the Long Store. The papers also show the types of products that the people of Mt. Clinton, Virginia were buying not only in everyday life, but also during the war years. The papers are organized chronologically and they are listed below in alphabetical order by company name.

There was a group of advertisements and letters found with materials from Series 3 which had been left in their original envelopes. The letters were taken out of the envelopes and placed in a folder. The letters were moved to Series 1 for convenience sake, and are all contained together in Folder 9, so they do not follow the chronological scheme of the other folders. One postcard from the State Normal School of Harrisonburg, Virginia, with seemingly no connection to the Long family, was found with the ledgers.

This series contains purchases and orders in ledgers compiled during the lifetime of the Long Store. The series contains 23 ledgers in total. Some ledgers show what customers ordered from the store and others show what the Long Store purchased from other companies in order to fulfill the needs of their customers. The order ledgers show what customers wanted to buy as well as who the regular customers were. They show the relationship that the Long Store had with its customers. Once the orders were delivered and were paid for, the order was crossed out with a red "X," indicating that the transaction was complete.

The purchase ledgers show what the owners of the Long Store purchased in order to meet the demand of their customers. Most of these ledgers are labeled with a date, what was bought on that date, and how much the order cost. Most ledgers were not specific with what goods were bought, but were specific with the pricing. Purchases were mostly labeled as "Goods" or "Tobacco" showing the importance of tobacco in that it was given its own category. Other ledgers simply state the name of the company being ordered from, rather than listing all the specific goods themselves.

This series contains records of the expenses and sales of the Long family store, as well as ten bank ledgers. The majority are specific to the First National Bank of Harrisonburg, Virginia. These indicate expenses and sales of the store, including specific company or personal names to whom the store is paying off bills or from whom it is receiving payment.

There are also three ledgers that indicate expenses of the store. The first ledger appears to be expenses organized by specific person or business. The latter two are organized by types of goods, including groceries, tobacco, dry goods, drugs, etc. The orders appear to be crossed out once they were acquired.

There are two other larger ledgers in the series. The smaller of the two appears to document the weekly sales of the store. There are several other receipts and calculations relating to the profit of the store stuck in the pages of the ledger. These loose papers were left there in order to preserve original order and context. The larger of the two ledgers seems to be a system of credit from a store in Johnsonville prior to the existence of Long Family Store in Mt. Clinton, Virginia. Samuel Long was known to have stores in many locations, so it seems prudent to assume it was one of his stores before Mt. Clinton. As with the previous ledger, there are calculations and a few documents of correspondence stuck in between the pages. They were likewise kept within to preserve original order.

This series consists of nine books: one "road book" ostensibly from Long's Store in Green Mount, Virginia and three account books and five daybooks from Long's Store in Mt. Clinton, Virginia. Daybooks record purchases of general household goods and merchandise, such as eggs, butter, pens, pencils, shoes, yarn, chickens, roosters, sugar, dye, matches, hats, and shovels. Account books typically record customer accounts, transactions and balances over time, and do not record itemized purchases.

This series is a collection of receipts that document the business between small town merchant W.E. Long and commission merchants such as Miller & Roller, Washington, D. C.; Acker & Long Produce, Philadelphia; Standard Oil Company; Brand Shoe Co., Roanoke; and J. J. Underhill Fruit & Vegetables, Baltimore which he supplied with butter, chicken, and eggs. Among the local merchants are: Snell Grocery, Harrisonburg; Hoge & Hutchinson, Staunton; Merchants Grocery and Hardware, Harrisonburg; L. W. Gaines, Inc., Harrisonburg; Worthington Hardware, Staunton; and National Biscuit Company, Staunton. Bills document the variety of merchandise including shoes, fabric, sugar, and coffee that Long purchased to supply his own customers. Fifteen cancelled checks from the First National Bank Harrisonburg date to 1920. A folder of bank deposit slips, primarily from First National Bank in Harrisonburg, are included.

This series consists of three record books from Mt. Clinton Post Office from 1879 through 1893. All three books are roughly the same size. However, Book One was received missing most of the front and back covers. Book Three was disassembled and boards discarded due to insect damage.

William E. Long was a postmaster at Chrisman, Virginia (1881-1887); Green Mount, Virginia (1889-1893); and Mt. Clinton, Virginia (1893-1897). William's father, Samuel, established and operated general stores and post offices in all three locations. It is unclear why the Mt. Clinton post Office records prior to William's tenure as Mt. Clinton postmaster remained in his possession. They are included in this collection due to their peripheral connection to Long.
