Carney (1982) has reported JHK photometry for 76 Hyades dwarfs. In connection with the present investigation, results of similar observations of field halo stars are provided along with some uvby photometry. In addition, older spectrophotometric and photometric data used previously for temperature determinations have been collected. The infrared and uvby data were obtained primarily with the objective of identifying binaries with dissimilar components among a sample of field halo dwarfs by comparing metallicity insensitive blue and infrared colors. Attention is given to 111 spectrophotometric scans of 89 stars, 67 uvby measures of 41 stars, 127 UBV measures of 87 stars, 147 (RI)J measures of 127 stars, 8 JHK measures of eight stars in the 'HCO' system, and 212 JHK measures of 137 stars in the 'CIT' system. The majority of these stars are dwarfs, and most of them are metal poor. The results of a search for binaries in 71 halo dwarf stars are also presented, taking into account a few other dwarfs of special interest.
