This series comprises muster books and pay lists of regiments. It provides a comprehensive means of establishing dates of enlistment, movements throughout the world, and of discharge or death. The first entry may show age on enlistment. An entry on the form "Men becoming non-effective", sometimes to be found at the end of each quarter's musters, shows the birthplace, trade, and date of enlistment of any soldier discharged or dead during the quarter.
From about 1868, at the end of each muster, may be found a Marriage Roll, which enumerates wives and children for whom married quarters were provided.
When the date of a volume is given as "March" or "September", it usually means the half year ending in the month stated.
There are no muster books or pay lists of units of the Royal Artillery serving in India, except occasionally in the earlier part of the series.
