In recent conversations with advanced graduate students (especially ABDs), I have learned that prestigious schools used to advise their students not to submit any papers for publication in grad school, calling this premature publishing, something that would not reflect well on the CV. However, recently, they've changed that advice and encourage those students to publish.
Some elite programs advise their students to only submit work to very prestigious journals (top-10, or even top-5): if you can't get into something of at least the level of Philosophical Studies, don't bother. Others propose that any good specialist or general journal publication is a plus on the CV. There is also different advice circulating about how many papers an ABD or newly-minted PhD should have on their CV. Is it true that one paper in a top-10 journal, or a couple of papers in good specialist or general journals would be enough to make one competitive? Would someone from an unranked program need more to stand a chance?
In the light of all these different forms of advice: What do readers of this blog think is sound publishing advice? What advice would you give an advanced graduate student/ABD about publishing (or if you are a recent PhD, what advice would you wish you had gotten when in grad school)? Do you think the prestige of the school matters for publishing strategies? I'm interested to hear readers' thoughts, especially as I hope to be an advisor to PhD students in the near future!
