When a person is desirous of procuring a published work upon any
subject, it is natural for him to inquire for the sources of information
from which the author has compiled that work. I have, therefore, without
wishing to be considered egotistical, concluded to issue this prospectus
to such as have an interest in the Battle of Gettysburg, that they may
know what I have already done, and what I yet propose to do, to
eliminate the history of that battle.
