The Associação Tchiweka de Documentação (ATD) is a cultural and historical organization dedicated to preserving and promoting the history of Angola's struggle for independence and broader African liberation movements. Established in 2006, ATD operates a comprehensive documentation center that houses a vast collection of archival materials, including text documents, photographs, and audiovisual content. These collections particularly focus on the political legacy of Lúcio Lara, a prominent figure in Angola's independence movement.

ATD offers a user-friendly online portal that facilitates access to these valuable resources for researchers, students, and the general public. Their library boasts over 7,000 titles, encompassing an array of books, periodicals, and archival documents from various contributors. Among their noteworthy initiatives is the "Angola – Nos Trilhos da Independência" project, which aims to document the personal histories of those involved in the liberation fight. Through ongoing efforts, ATD aspires to enhance understanding and appreciation of Angola's rich historical tapestry while addressing any gaps or inaccuracies in their collections.
