In all, there were 20 record books for slave liberations. While the format changed over the years, the general system used by the colonial government was the following: name of slave, place of birth (if available), age, place of liberation within the colony of Senegal, date of liberation, and name of the colonial administrator."

"Between 1857 and 1903, 28,930 enslaved Africans walked away from their African masters and sought freedom and freedom papers from French colonial officials in Senegal. Who they were, where they came from, and how they made their way to freedom are central questions we are asking." https://cesta.stanford.edu/research/senegal-liberations-project
