Chris at "Mixing Memory" has a post in which he talks a bit about Franz Brentano, so I thought I'd put up a few online links for those who are interested in being introduced to the awesomeness that is Brentano. For Brentano is lots of fun; I don't study him, but I've never read anything by him that was not well worth reading.
* The Marxist Psychology Archive has translations of the first two chapters of Psychology from an Empirical Standpoint.
* The Stanford Encyclopedia of Philosophy has a general article on Brentano and an article on his theory of judgment. Naturally, he also receives some mention in the articles on intentionality and on consciousness and intentionality.
* The Maverick Philosopher has some posts on Brentano. He also has an online article on Brentano on Existence.
* Barry Smith has a number of articles on Brentano's philosophy.
* Dallas Willard has an article reflecting on Brentano's invisibility.
ADDED LATER: Also, there's an examination of Brentano on the subject of 'existential import' at The Logic Museum.
