Summary Some differential catalogues of reference stars around extragalactic radio sources obtained from photographic and CCD-observations by different observatories are considered. Compiled catalogue of star positions in fields 40'x 40' for reduction of optical observations ERS on telescopes with CCDcameras is intended. Photographic observations fields around of 74 ERS were made in Pulkovo Observatory, around 115 ERS - in Observatory of Kiev University, around 188 ERS - in Rumanian National Observatory at Bucharest. 208 fields around ERS were obtained in Nikolaev observatory on telescope with CCD-camera. We included to catalogue the selections from La Palma catalogues CMC-9 and CMC-14, Kiev catalogue KMAC1-CU, ERL catalog for 398 ERS by Zacharias and the selections from Kharkov catalogue XC1. Astrometric positions for 196600 stars brighter than 17 magnitude for 240 fields around ERS are presented. A comparison of our results with those of other authors is made. For realization of optical CCD-observations of faint astrometric extragalactic radio sources (ICRF ERS) with the purpose of their connection to VLBI-observations (system ICRS), a compiled catalogue of more than 196600 reference stars of 10-17 magnitude was obtained for 240 fields of declinations from -30 to +80 declination with a center ERS. The comparison positions of stars with the catalogues UCAC3 and Tycho-2 was made. For majority of chosen fields from the compiled catalogue the average external accuracy was about 0:05 - 0:08". An internal accuracy of positions on both two coordinates was not worse 0,11". All positions of stars in the compiled catalogue are given: for stars chosen from UCAC3 by proper motions on epoch and equinox J2000.0, for another one on epoch of observation. ***
