My introductory syntax class is currently covering bare phrase structure. Unfortunately, we're using An Introduction to Syntactic Analysis and Theory which (while covering morphology, constituency, X'-theory, and a whole lot else in fair depth) does not cover modern bare phrase structure, and I could use some supplemental reading.
Where can I learn about bare phrase structure? Do introductory texts exist, or is it new enough to be only laid out in papers? I would particularly like to get a better handle on vP shells, I understand the motivation for them in terms of making our underlying structure simply semantics but their integration into the overall theory I am less confident about.
