A sample of galaxy pairs identified from the LAMOST spectral survey and
  the Sloan Digital Sky Survey
  A small fraction($<10\%$) of SDSS main sample galaxies(MGs) have not been
targeted with spectroscopy due to the the fiber collision effect. These
galaxies have been compiled into the input catalog of the LAMOST extra-galactic
survey and named as the complementary galaxy sample. In this paper, we
introduce the project and the status of the spectroscopies of the complementary
galaxies in the first two years of the LAMOST spectral survey(till Sep. of
2014). Moreover, we present a sample of 1,102 galaxy pairs identified from the
LAMOST complementary galaxies and SDSS MGs, which are defined as that the two
members have a projected distance smaller than 100 kpc and the recessional
velocity difference smaller than 500 $\rm kms^{-1}$. Compared with the SDSS
only selected galaxy pairs, the LAMOST-SDSS pairs take the advantages of not
being biased toward large separations and therefor play as a useful supplement
to the statistical studies of galaxy interaction and galaxy merging.
