The Earthquake Engineering Online Archive and e-library is a database of significant, publicly-funded research and development literature, photographs, data and software in earthquake, structural, and geotechnical engineering.

The archive is updated daily. The UCB-EERC reports, PEER Center reports, selected UCB-SEMM reports, selected UCB-GEOTECH reports, other university research reports, and selected papers and reports from the NISEE Online Library are included in the archive with earthquake damage images, experimental data and movies, and research software.
