"Nightfall and Other Stories" contains twenty of Asimov's short-stories published in a variety of magazines between 1941 and 1967 (though most are from the 50s).

Some of these are a little dated now but nevertheless display Asimov's very readable writing style and are accompanied by autobiographical comments or sometimes how the story originated. These provide a fascinating insight into Asimov's personality and life as a writer.

The eponymous "Nightfall" stands out as the most significant of the stories but "Jostess", "Breeds there a man", "It's such a beautiful day" and "Segregationist" are all very good two.

Asimov makes it so easy to read his writing though that you'll enjoy them all
