Through LAMOST DR5, a total number of 9.02 million spectra were released to the international community. Besides, a catalogue which has provided stellar parameters of 5.34 million stars was also released internationally in this data set. The catalog will also be included in CDS VizieR. LAMOST DR5 has thus resulted in the largest public spectral set and stellar parameter catalogue in the world at present.
