What are the Best Books on Credit Investing?

Inside the Yield Book: Industry staple that doesn't get mentioned much on here. Conceptual.

HY Debt, Bagaria '15: relatively shorter, gives a good overview of different credit markets.

Leveraged Financial Markets, McGrawHill: Along the same lines as the above, but more detail.

Pragmatist's Guide to LevFin: Good overview of markets and concepts. More on the analysis side, so I'd definitely recommend.

Bond Math: There's going to be at least one thing in this self explanatory book that you will have missed and will be interested to discover. Very good breakdowns.

Active Credit PM in Practice, Bohn and Stein: Covers the foundations of credit risk modeling.

LSTA's Complete Credit Agreement Guide: Excellent yet daunting reference.

Distressed Debt Analysis, Moyer: Valuable for anybody in HY.

Fixed Income Relative Value Analysis: Applying Principal Components Analysis to different FI areas. Brush up on your linear algebra for this one.

Quantitative Credit PM: Not as tough as you might guess, but it has things I haven't seen covered elsewhere such as DTS and Liquidity Cost metrics.

Managing Credit Risk, Altman and others '07 or '09: lots of stuff, kind of a blur. Still reference here and there. Worth the $10 used.

Fixed Income Securities, Tuckman: Fundamentals and then basically interest rate modeling. Not to be confused with Martiellini, Priaulet, which is also good.

Advanced Bond PM '05: kinda dated compilation of chapters from other wiley credit books. Worth it if you find a cheap used copy.

Leveraged Finance, Fabozzi '07: decent overview with a good focus on Lev Loans and CLOs if I recall correctly.

Loan Workouts and Debt for Equity Swaps, early 00's: relatively short. good overview of the process.

Will add more later.
