The original coding sheets are archived in Butler Library, Buffalo State College, Buffalo, NY 14222. One coding sheet stands for one vessel. That vessel might be whole, it might be represented by several rim sherds, or it might only be represented by a single rim sherd. The collection the sherd or vessel is from along with any catalog numbers are written on the back of each coding sheet. A coding sheet in this project is represented by a row of data in either an .xls or .txt file.
