A Companion to Metaphysics provides a survey of the whole of metaphysics and includes articles by many of the most distinguished scholars in the field.
Jaegwon Kim (born 1934 in Daegu, Korea (now in South Korea)) is a Korean-born American philosopher currently working at Brown University. He is best known for his work on mental causation and the mind-body problem. Key themes in his work include: a rejection of Cartesian metaphysics, the limitations of strict psychophysical identity, supervenience, and the individuation of events. Kim's work on these and other contemporary metaphysical and epistemological issues is well-represented by the papers collected in Supervenience and Mind: Selected Philosophical Essays (1993).
Kim's philosophical work focuses on the areas of philosophy of mind, metaphysics, action theory, epistemology, and philosophy of science.
It is a good starter for one who is not so familiar with Metaphysics. It covers Metaphysics into the mid-90s, depending on which edition, but missed a lot of new stuff in the ensuing 20 years, which is a shame, since the new stuff needs to be out there as well.
Having said that, there is a spottiness to the sophistication which may jar some readers who may not be as read in modern analytical philosophy (non-degreed, maybe?). However, there are great references at the end which can give one a good feel for the particular subject and they mention many summary articles (i.e., articles that exercise multiple positions on a particular subject). This will help both the more amateur and more sophisticated student of philosophy, as summary articles usually cite much of the extant literature on a subject. It helps peel the layers of the onion (and also is a case study in the specialization that analytical philosophy has become).
