When typesetting bibliography manually, I typically use \frenchspacing. You may, but that is increasing spacing (at least around punctuation). But my publisher would like tighter-than-normal spacing. Is a condensed font that complements your text face available? That, and reducing the font size should be the first things to look at. If neither will work for you, there is a sledge-hammer you can wield: \kerncharacters. Depending on the font and your sensibilities, you might get away with \kerncharacters[-0.07], but even at -0.03 some look bad. You will lose ligatures.
Thank you for the suggestion, but I am not looking for typographical solutions, being a typographer myself. I asked explicitely for TeXnical advice to achieve tighter spacing - maybe I should have made clear that I don’t mean character kerning but only the handling of "space" glyphs.
