The information accessible here is produced from the Khipu Database, but mimics the layout of the tabular format first invented by the Aschers. There are three parts to each set of khipu data: a "Heading" page which lists overall characteristics of the khipu, including museum number and cord spacing; "Pendant Detail", which contains specifics about each pendant and subsubsidiary; and a "Notes" section, where any other observations are recorded. The different pages are accessed by tabs at the bottom of the screen. These data are accurate to the best of our knowledge, but it is always possible that further analysis or re-study may change the information presented here.

The late Dr. Hugo Pereyra, a Peruvian engineer and khipu scholar, made a thorough study of the collection of khipu from Pachacamac. Khipu studied by Dr. Pereyra are identified with the prefix "HP" followed by his numeric designation.

Many of the khipu originally studied by the Aschers have been restudied by Dr. Urton. The data below reflect Dr. Urton's re-study of these khipu, including information on features such as twist direction, cord attachment, and knot direction--features not originally recorded by the Aschers. The UR number is the original Ascher number prefaced by a "1", e.g., AS032 is listed as UR1032.

AS khipu without a corresponding UR number have not been re-studied by the KDB project.
