There are a couple of ways to obtain my book, Commercial Loan Analysis: Principles and Techniques for Credit Analysts and Lenders.
You may order an electronic version from me directly. I have electronic versions of both the original edition and a new second edition. Contact me via email to order.
You may also order on Amazon. I am currently out of hard copies of the first edition; although, I am working to get the second edition printed soon.
Finally, you can check out the Financial Statement Analysis section of this website. You will find that selected sections of the book (particularly financial ratios) are presented there.
Thanks for reading!
