Trouble with apostrophes

There's a column in the Riverside Press-Enterprise about problems with apostrophes. And readers have written in to share some mistakes.

Victoria Cunningham stumbles over "Bridget Jones's Diary." "I thought it should be Jones'." The Associated Press style gods agree. But Lynne Truss, discussing the subject in "Eats, Shoots & Leaves," cites "Fowler's Modern English Usage," which says "modern" names should end "Keats's poems," ancient names should end "Achilles' heel," institutional names (St. Thomas' Hospital) are up to the institution. And just about everything is open to violent argument.

Someone else takes the paper to task for adding apostrophes to such stores as Ralphs, Vons and Albertsons. The columnist must admit that he, too, has committed those errors.
