    "abstract": "We report on the demonstration of light storage for times greater than a\nsecond in praseodymium doped Y$_2$SiO$_5$ using electromagnetically induced\ntransparency. The long storage times were enabled by the long coherence times\npossible for the hyperfine transitions in this material. The use of a solid\nstate system also enabled operation with the probe and coupling beam counter\npropagating, allowing easy separation of the two beams. The efficiency of the\nstorage was low because of the low optical thickness of the sample, as is\ndiscussed this deficiency should be easy to rectify.",
