Spectrophotometry (wavelength = 3400-5100 A) has been obtained for the nuclei of 13 cD galaxies in cooling flows. Spectral anomalies are found in 8 of the objects, consisting of abnormally strong forbidden O II emission or excess flux effects. Consideration is given to metallicity effects, the relationship between UV excesses and the presence of massive OB stars formed from the cooling flows, and low-level effects related to accretion.
