Abstract

A brief overview of the interstellar absorption-line observations of the Magellanic clouds is given, with particular emphasis on the results obtained by the ESO Key-Program for the Magellanic Clouds. It is shown that high resolution interstellar observations towards bright MCs sources can probe the large scale distribution of the interstellar gas, revealing their 3-dimensional structure. Current views of the intermediate velocity clouds are challenged by new observations, which show that this gas is clumpy, in the foreground and of low elemental abundance. The LMC shows a complex structure and the case for a substantial amount of gas emitting in 21-cm at V≈ 270 km s−1 behind the stellar system is receiving new support. The absorption line data accumulated so far show that the SMC is definitively a disrupted system composed of at least four separate bodies.
