Books to recommend for High Yield research?

Was wondering if any one has recommendations for books on how to do high yield (or junk bonk) research? Started a job 6 months ago as an analyst, pretty comfortable with the basics of equity research and now going to move more into hy side. Thanks

Not a book, but check out this link: Presentations from BNP Paribas’ Annual HY Conference (2006)… might help you out a bit.
