We present the Blue Stragglers (BSS) Catalogues extracted from the photometric data base of 74 Galactic GCs published by Piotto et al., 2002, Cat. <J/A+A/391/945>. All the clusters were observed in the F439W and F555W photometric bands pointing the HST/WFPC2 camera to the central core. Candidates were selected according to their position in the colour magnitude diagrams. A detailed description of the selection process is given in the paper. We give for each cluster a list of blue straggler candidates together with their photometric data.
