Barclay's first bookbinding shop was located in
Cornhill, Boston, where other printers and book sellers had established themselves. In colonial America, bookbinders were an obscure group of tradesmen who rarely took official credit on the title page of the works they bound. Because of limited resources, with virtually no patronage from royalty or wealth, with little access to superior sources of materials, along with the unstable and wavering economic and political factors present in the colonies, their work was generally of average quality compared to that of European bookbinders. Very often they combined the business of bookbinding with bookselling and sometimes with printing and publishing. There is no known bookbinder of American origin that was known to sign or label the works he bound. The two exceptions in the American colonies both emigrated from Scotland; Andrew Barclay and Samuel Taylor, who worked out of Boston and Philadelphia respectively. In 1764 while
Isaiah Thomas was an apprentice for
Zechariah Fowle, now operating a printing press on his own, he printed ''Tom Thumb's playbook; To teach children their letters as soon as they can speak'', which he commissioned Barclay for the bookbinding, and which bears Barclay's imprint. In September and October 1771 ads advertising bookbinding by Barclay appeared for six consecutive weeks in Thomas' patriot newspaper,
The Massachusetts Spy. : Both Barclay and Taylor are known for their elaborately engraved trade labels which are found on the inside cover of their works. Barclay's signature label is more fanciful and somewhat more widely known than that of Taylor. There are five known works where Barclay's labels can be found, while there are three known works where those of Taylor occur. Consistent with Barclay's Loyalist sympathies, he bound works by William MacAlpine,
Nathaniel Hurd and John Hicks who fled Boston for
Halifax with the British Army, all of whom had written in opposition to the prospect of American independence. When the American Revolutionary War broke out Barclay as a Loyalist assumed an active role by joining the Royal North British Volunteers against the rebels in Boston. When the British troops evacuated Boston in March 1776, he was forced to abandon his bookbinding wares and sailed for Nova Scotia, and soon thereafter to New York, where he remained until the end of the war; before leaving New York Barclay was honored by
Sir Guy Carleton, and given a command over a company of Loyalist refugees bound for
Shelburne, Nova Scotia, where he settled into a life of farming and ranching and was seldom involved in bookbinding. Andrew Barclay died in Shelburne, Nova Scotia, on 2 July 1823, at age 86. His estate was appraised at £280. The various items listed in his will included a set of bookbinder's tools and other items. ==Works bound by Barclay==
