  Data from 11 years of continuous spectroscopic observations of the active RS
CVn-type binary star EI Eridani - gained at NSO/McMath-Pierce, KPNO/Coude Feed
and during the MUSICOS 98 campaign - were used to obtain 34 Doppler maps in
three spectroscopic lines for 32 epochs, 28 of which are independent of each
other. Various parameters are extracted from our Doppler maps: average
temperature, fractional spottedness, and longitudinal and latitudinal
spot-occurrence functions. We find that none of these parameters show a
distinct variation nor a correlation with the proposed activity cycle as seen
from photometric long-term observations. This suggests that the photometric
brightness cycle may not necessarily be due to just a cool spot cycle. The
general morphology of the spot pattern remains persistent over the whole period
of 11 years. A large cap-like polar spot was recovered from all our images. A
high degree of variable activity was noticed near latitudes of approx. 60-70
degrees where the appendages of the polar spot emerged and dissolved.
