  We present a brief technical outline of the newly-formed 'Detection of
Spectroscopic Differences over Time' (DS/DT) project. Our collaboration is
using the individual exposures from the SDSS spectroscopic archive to produce a
uniformly-processed set of time-resolved spectra. Here we provide an overview
of the properties and processing of the available data, and highlight the wide
range of time baselines present in the archive.
