I recently subscribed to Ellen Ostrow’s excellent newsletter, Beyond the Billable Hour, and I would recommend it for law students who are planning to join a law firm after they graduate.  The newsletter dispenses useful tips on career strategies and work-life balance aimed primarily at women attorneys, but there’s plenty of valuable information here for men as well.  Ostrow’s website also has a handy "Resources and Links" page that includes a lengthy bibliography on every aspect of managing your legal career.
