"Urton's work is scholarly and painstakingly thorough and is a valuable contribution to our understanding of Inca inscription that makes good use of ethnographic and ethnohistorical work on the Andean region." -- The Journal of the Royal Anthropological Institute "This is by far the most important monograph on Andean systems of information registry since the Ashers' volumes in the late 1970s. Urton provides a platform for a whole new generation of studies." -- Frank Salomon, Professor of Anthropology, University of Wisconsin-Madison In an age when computers process immense amounts of information by the manipulation of sequences of 1s and 0s, it remains a frustrating mystery how prehistoric Inka recordkeepers encoded a tremendous variety and quantity of data using only knotted and dyed strings. Yet the comparison between computers and khipu may hold an important clue to deciphering the Inka records. In this book, Gary Urton sets forth a pathbreaking theory that the manipulation of fibers in the construction of khipu created physical features that constitute binary-coded sequences which store units of information in a system of binary recordkeeping that was used throughout the Inka empire. Urton begins his theory with the making of khipu, showing how at each step of the process binary, either/or choices were made. He then investigates the symbolic components of the binary coding system, the amount of information that could have been encoded, procedures that may have been used for reading the khipu, the nature of the khipu signs, and, finally, the nature of the khipu recording system itself-- emphasizing relations of markedness and semantic coupling. This researchconstitutes a major step forward in building a unified theory of the khipu system of information storage and communication based on the sum total of construction features making up these extraordinary objects.

Wonderful
Fantastic buy! This contains everything I need (minus a phone), and because it zips up, I know everything is secure. I recommend this product.

Exactly what I needed for traveling!
This Amazon Basics Travel Passport Wallet Organizer is amazing value for the price. It has multiple easily accessible slots & pockets that can be used for credit cards, boarding passes, receipts, pens, and currencies if traveling internationally. The wallet has a zipper which can safely secure folded documents such as immunization records, marriage certificates, and citizen forms if needed. The functional design is larger than I anticipated and the material feels well-made, solid, and looks nice. I could not fit the wallet in my pocket, but it easily fits into a backpack or purse. If I happen lose this or misplaced this one, I will be purchasing this again.

Great Hold-All
This seems to be well-made and I like the configuration. It should hold passport, ID, credit cards, cash and any travel docs with no problem. It is a bit larger than I expected, however, so that will have an impact on what sort of purse, belt bag, or etc. I use to carry it. My biggest issue with this and ANY RFID blocking wallets/purses/etc. is that I wish the manufacturers would add a sewn in tag or imprint on the product itself that SAYS it's RFID blocking. After time goes buy it gets hard to remember which items in your travel stash are or aren't. I've used a Sharpie to mark this one, but it would be nice if the manufacturer did so professionally.
