In Gregorio-Hetem et al. (1993) and Castilho
(1995) the far-infrared emission of
Li-rich giants (LRG) was analyzed, based on data from the IRAS
Point Source Catalog for the sample of LRG
discovered by Brown et al. (1989, hereafter BSLD). BSLD
obtained coudé spectra for 644 giants,
and found 9 new LRG (), which corresponds
to
1.5
of their sample of G-K giants. They also
found 8 stars with

their sample).
In terms of IRAS colours the distribution of LRG
is different from that of Li-normal giants.
A large number of LRG are found
within the "box" -0.7 < [25-12] < -0.3 and
0.0 < [60-25] < 0.25 as shown by Gregorio-Hetem et al.
(1993) (these colours are defined by: ), where

Following the criterion of flux ratios given above, we have selected 280 candidates from the IRAS PSC and started an all sky survey of these stars (Barbuy et al. 1995, 1996). In this paper results of this survey are presented.
In Sect. 2 (click here) the selection criterion and the observations are described. In Sect. 3 (click here) the results are presented and discussed.
