I'm a big fan of annotated books and Sherlock Holmes. How would you rate the annotations? I think I have read somewhere that the Klinger edition is the ultimate Sherlock Holmes reference work, the annotations are so extensive and detailed that it really takes you forever to get through the stories. I found the annotations very good but sometimes wondered if it was really needed to explain everything in such detail. Luckily, you can take the reading piece by piece since Sherlock Holmes collected works are 50+ short stories and 4 rather thin novels. I also found that the old style illustrations from the original publication (Strand magazine?) were to my taste. The design of these volumes is overall brilliant.
