"The purpose of this pamphlet is two-fold. First, to provide advice on how to be effective and efficient in pension ledger research. Second, a finding aid to pension ledgers and pension vouchers. These are Revolutionary War pensioners and some invalid pensioners of the War of 1812. A finding aid found in the Microfilm Reading Room of the National Archives, Washington, D.C. is the basis for this work"--Introduction p.vii.
