I usually google it (something like "author name books (list OR chronology)") and it is found on either the author's web site, or wikipedia, occasionally another site. I then paste the info into a document, along with any notes I want to make, run it through Mobipocket Creator (I guess you could email it to Amazon for conversion), and put it on my Kindle. Ta-da!
I also have a file with summaries about free books I have downloaded, but not read yet, so I can check back, in case I forget what the book is supposed to be about.
