So far there has been a discussion on the collection and use of data rather than objects. The physical objects, as examples of the material culture, are another important line of evidence. Ethnographic collections have been used by archaeologists to better understand nonindustrial material culture, and some have been directly compared to archaeological collections or analyzed using similar methods. Despite their utility, these are not the collections the archaeologists themselves would have made given the opportunity. This is, at least in part, because museums and wealthy individuals do not choose items that represent the bulk of the archaeological record. For example, collectors and the viewing public generally prefer painted vessels in good condition. Plain cooking vessels are underrepresented and heavily used vessels are rarely included, although fragments of such vessels dominate many archaeological collections.
Ethnoarchaeologists may collect objects as well as data with the needs of archaeologists in mind. Such collections may allow for more detailed artifact analysis similar to that undertaken for archaeological objects, and permit reanalysis and use as training material by other researchers who could not visit the field site. Collections both enhance the original study and help other archaeologists to learn and benefit from ethnoarchaeological work. For example, Kalinga Ethnoarchaeological Project researchers collected both painted water jars and plain cooking vessels, now curated at the Arizona State Museum. These collections were an integral part of research by Skibo and Kobayashi on cooking vessel use. During his Nunamiut research, Binford collected faunal bone from both recently butchered animals and older Nunamiut sites. These materials are stored at the Museum of New Mexico and also at the University of Arizona, where Mary Stiner is directing additional analyses.
