An Author Thing Coming
Music box? CDCASE
Better part of a loaf? HALF
Theme: Names of authors in phrases
People who recite “Jabberwocky” door-to-door? CHRISTMASCARROLLERS
Fictional tornado shelter? BAUMSHELTER [particularly apt in
The Wizard of Oz]
Periods when Harry Potter books are unavailable? ROWLINGBLACKOUTS
Not as hard to pronounce as some 17th-century poetry? EASIERSAIDTHANDONNE

Crossing LEWIS and WILDE seems a bit unsporting since the clues are book titles.
Mystery writer John Dixon ___ CARR [Would “Today’s theme vehicle” work?]
Dashingly? ATARUN [Isn’t the idiom “on a/the run”?]
Excellent server ACER [Another constructor who just looks at lists of clues rather than thinking --- or reading this space]
Stroked SWAM [though one strokes during the process of swimming, the two are not synonymous]
The theme was so good that it overcomes the flaws.
