"Isaac Bickerstaff" is a common pseudonym in almanacs.

Erroneously attributed by Evans to Benjamin West. The actual calculator appears to be Nathan Daboll. The astronomical and horological notes on the calendar pages are frequently identical with or similar to those in The New England almanack and gentlemen and ladies diary for 1788 (New London), calculated by Daboll under the pseudonym of Edmund Freebetter. The calculations for the moon are identical throughout. The other calculations on the calendar pages vary to a degree reflecting the difference in meridian between New London and Providence.

West and Carter, the publisher, severed relations with the 1781 issue. West's almanac was published thereafter at Providence by Bennett Wheeler as the North American calendar, while Carter continued the New England almanack over the Bickerstaff pseudonym with which West is often identified.
