Searching for a word or an author in an encyclopedia or dictionary may not always suffice. If you are writing an essay or paper or preparing yourself to do so, you’ll want to search in more depth. For this purpose, various other resources are available in the University Library.
You will thus find parts of a series about a number of philosophers called 'Critical assessments of leading philosophers' in the reading room. This series consists of critical assessments by other scholars of certain subjects in the work of a particular philosopher. For example, the second series of the Critical assessments series covers articles about John Locke such as 'Locke's political arguments for toleration' and 'Locke on the death penalty'. Sometimes those articles were published in a journal at an earlier stage. The notes to the articles enable you to trace other texts.
An overview of all parts of the series 'Critical assessments of leading philosophers' can be found here.
The Routledge philosophy guidebook operates from another point of view: this series focuses on a single philosopher and one of his works. Examples are the 'Routledge philosophy guidebook to Descartes and the ‘Mediations'' and the 'Routledge philosophy guidebook to Nietzsche on art'. An overview of all available parts of this series (some are available as an electronic book) can be found here.
