We present the results of a flux density monitoring program of extragalactic radio sources with the Effelsberg 100-m telescope. Data for 53 sources are listed from observations between 1991 and 1995/1996 in the frequency range from 1.4 GHz to 32 GHz[*]. The sources have either been identified by EGRET on board CGRO at a different level of confidence or at least are candidates for showing up in the $\gamma$-ray range. The data will be useful for studies of the relationship of $\gamma$-ray activity to radio activity.

Key words: $\gamma$-rays -- extragalactic radio sources -- quasars -- BL Lacs -- variability
