On-line casuistry

I thought it would be fun for people to post links to any on-line manuals of casuistry with which they are familiar. Here are some that I have found:
A Brief Text-book of Moral Philosophy by Charles Coppens
(Here is the definition of a lie: A falsehood, or lie, is speech contrary to one's mind.)
Moral Philosophy: Ethics, Deonoology and Natural Law by Joseph Rickaby
(Here is his definition of 'lying': a formal lie is saying what one believes not to be true, or promising what one intends not to perform: briefly, it is speaking against one's mind.)
Catholic Moral Teaching / by Joseph Mausbach
(Here is a section on lying.)
Elements of Moral Theology by John J. Elmendorf
(Here is the section on lying.)
