Telescope* resolved stellar population imaging [@dalcanton09]. While previous surveys comprehensively cover high surface brightness systems in flux-limited samples, the LVL survey, although also biased toward high surface brightness galaxies, provides a multi-wavelength inventory of a statistically robust, approximately volume-limited sample, which is well-suited for studies of dwarf galaxies. By studying the nearby, low-luminosity galaxies, we can increase the dynamic range covered by the luminosity-metallicity and mass-metallicity relationships, which will help to better constrain the slopes.

Low-Luminosity LVL Sample {#sec:Sample}
-------------------------

We selected a sample of 42 low luminosity galaxies in the LVL survey in order to obtain new MMT high-resolution spectra. These low luminosity spirals and dwarf irregulars span a range in distance of 2.5 $\leq$ D $\leq$ 14.0 Mpc[^2]. The luminosities for this sample range in the near-IR (determined from IRAC [@fazio04] photometry) from $M_{[4.5]} = -13.1$ to $-21.7$, with *B*-band magnitudes of $-10.8 \geq M_B \geq -18.8$. Most of the objects were chosen because they lack “direct" oxygen abundances in the literature, their abundance estimates are dated, or were studied with instruments which were known to have problems.

Although not LVL objects, two additional galaxies were added to the sample (increasing the sample total to 44 objects) because
