I’ve been asked if I can recommend some sources on grammar for lawyers who want to improve their knowledge. Yes I can. I’ll start with websites:

Purdue University’s Online Writing Lab (OWL).

• http://owl.english.purdue.edu/

The Tongue Untied

• http://www.grammaruntied.com/

Grammar Girl (Mignon Fogarty) and her Quick-and-Dirty Tips

• http://grammar.quickanddirtytips.com/

And some books:

• Mignon Fogarty, Grammar Girl’s Quick and Dirty Tips for Better Writing (Holt 2008).
• Patricia T. O’Conner, Woe is I: The Grammarphobe’s Guide to Better English in Plain English (Riverhead Books 1996).
• Margaret Schertzer, The Elements of Grammar (Macmillan 1986).

And a reference:

• Bryan A. Garner, Garner’s Modern American Usage (3rd Ed. Oxford U. Press 2009).
