This project includes pdf reports and metadata covering work on the South Caucasus Pipeline Expansion project between 2013 to 2018. The Internet Archaeology article provides a summary and introduction to the various sites, which are then reported on in more detail in the archived reports. The project follows the line of the previous Baku-Tbilisi-Ceyhan/South Caucasus Pipelines project, about 10 years earlier that involved portions of many of the same sites, although there were substantial differences in results. These are the subject of Taylor, P.M. and Maynard, D.J., 2011. 'Archaeological excavations on the BTC pipeline, Azerbaijan', Internet Archaeology 29. (https://doi.org/10.11141/ia.29.1) and a linked ADS archive (https://doi.org/10.5284/1000411).
