Beginning in the early 1990s with support from the United States Agency for International Development (USAID), ARCE engaged in vital conservation work at monuments and sites throughout Egypt, leading to a unique collection of material documenting conservation projects that constitute the ARCE Conservation Archives. In total, the Conservation Archives includes 79 collections, each documenting a different project conducted in Egypt.

The Conservation Archives covers a wide range of Egyptian history spanning over 7,000 years. Geographically and historically diverse, the projects include Pharaonic, Coptic, Islamic, and other Egyptian cultural heritage sites of significance. 

Each collection contains photographic and written material including 35mm and 120mm color and black & white slides, born-digital images, technical reports, and various grant-related documentation, in addition to a select number of project artifacts and architectural drawings. There are around 70,000 photographic slides, 200,000 images, 1,200 documents, 1,000 drawings, as well as a small selection of artifacts and multimedia content. 

The ARCE Archives website launched in Fall 2020 with five collections from the Conservation Archives. The online archives includes the two projects previously published on UCLA's International Digital Ephemera Project (IDEP) site, the Conservation of the Tomb of Anen in the Theban Necropolis, and the Conservation of the Roman Wall Paintings in Luxor Temple, and three additional projects: the Conservation of Aslam al-Silahdar mosque in Historic Cairo, the Architectural Conservation at the Red Monastery in Sohag, Egypt, and the Preservation of the Funerary Enclosure of King Khasekhemwy (Shunet el-Zebib) in Abydos. ARCE is currently seeking out additional funding to digitize and publish the remainder of the collections in the Conservation Archives.
