Here's a great opportunity for those who have computers which can search Chazal for various phrases: How many times do you find the phrase "yeshivas shem v'ever", and how many times do you find the phrase "yeshivOs shem v'ever"?

Or does someone want to claim that it is "yeshivos" even without the vav?
