The directory included here contains the files used by the original Alpha 4 version of the Spanish Dialects, or 'spandial,' database created by the principle investigators of the New Mexico and Colorado Spanish Survey. Documented modifications to the content have been made in order to protect the privacy of the survey consultants. In particular, multiple fields have been removed from the 'MASTER.DBF' table included in the database. The Alpha 4 files included in the 'spandial' directory are considered to be the minimum required to recreate the database within a legacy or emulated Alpha 4 application.
