The multiwavelength observation is one of the main achievements in modern astronomy. This paper is intended as a review of the modern multiwavelength surveys, an introduction and a discussion of the LAMOST observations. We first review the international surveys on individual wavelengthes. In X-ray wave band, we introduce the main X-ray Satellites, such as ROSAT, ASCA, Chandra and XMM-Newton. We then describe the surveys including SDSS, Deep and 2dFGRS in optical; 2MASS and SWIRE in infrared; and NVSS, FIRST in radio as well. According to the spectral ability and the observational mode of LAMOST, we suggest the suitable objects for LAMOST observations, and discuss the cross-identification for selecting candidates.
