  We present new Very Large Array HI spectral line, archival Sloan Digital Sky
Survey, and archival Spitzer Space Telescope imaging of eight star-forming blue
compact dwarf galaxies that were selected to be optically compact (optical
radii less than 1 kpc). These systems have faint blue absolute magnitudes (M_B
>= -17), ongoing star formation (based on emission-line selection by the H
alpha or [OIII] lines), and are nearby (mean velocity = 3315 km/s = 45 Mpc).
One galaxy in the sample, ADBS 113845+2008, is found to have an HI halo that
extends 58 r-band scale lengths from its stellar body. In contrast, the rest of
the sample galaxies have HI radii to optical-scale-length ratios ranging from
9.3 to 26. The size of the HI disk in the "giant disk" dwarf galaxy ADBS
113845+2008 appears to be unusual as compared to similarly compact stellar
populations.
