Early almanacs were permanent tables of the apparent motions of the sun and moon, from which astronomical data for any year could be calculated. In the 15th century, almanacs began to be prepared for definite periods, such as 10 or 30 years, and in the 16th century, for a single year. From this period astrological and meteorological predictions were also included, alongside other information. (OED) The Folger Collection development policy targets acquisition of 16th- and 17th-century English almanacs.

Early English almanacs were typically attributed to a single author, sometimes whose attribution sometimes continued after the author's death.
