The British Institute for Libyan and Northern African Studies (BILNAS), formerly known as the Society for Libyan Studies from 1969 to 2022, supports research, scholarship, and collaboration relating to the history, archaeology, culture, art, and literature of Libya and Northern Africa.

The BILNAS Archive has been housed at the University of Leicester since 2012. It holds a number of documents, photographs, drawings, maps, plans, and a great deal of unpublished data relating to archaeological projects in Libya from the early 20th century onwards undertaken mainly by British scholars, sometimes in collaboration with Libyan colleagues, in sites such as Sabratha, Lepcis Magna, Ghirza, the Fezzan, Tocra, Cyrene, Sidi Khrebish, and El Merj. The archive can be browsed online, where it is mostly organized by person or by excavation. Materials can be consulted in-person at the University of Leicester.

The materials from some of the major excavations are regularly being digitized and made openly available via Archaeology Data Service. So far, material from the Sabratha excavations of 1948-51 are online.

BILNAS has also made an extensive collection of photographs from its archives available online at FLICKR. The photos are historical as well as more recent.
