  We present a multi-wavelength compilation of new and previously-published
photometry for 55 Galactic field RR Lyrae variables. Individual studies,
spanning a time baseline of up to 30 years, are self-consistently phased to
produce light curves in 10 photometric bands covering the wavelength range from
0.4 to 4.5 microns. Data smoothing via the GLOESS technique is described and
applied to generate high-fidelity light curves, from which mean magnitudes,
amplitudes, rise-times, and times of minimum and maximum light are derived.
60,000 observations were acquired using the new robotic Three-hundred
MilliMeter Telescope (TMMT), which was first deployed at the Carnegie
Observatories in Pasadena, CA, and is now permanently installed and operating
at Las Campanas Observatory in Chile. We provide a full description of the TMMT
hardware, software, and data reduction pipeline. Archival photometry
contributed approximately 31,000 observations. Photometric data are given in
the standard Johnson UBV, Kron-Cousins RI, 2MASS JHK, and Spitzer [3.6] & [4.5]
bandpasses.
