I'm looking at old newspapers on microfilm in the library. This would be tolerable, except that my iPod broke. Also, I am looking at this book's footnotes to find which issues of The Los Angeles Times are relevant to my topic, which saves me a lot of time because I don't have to read through all of them myself. But occasionally there will be an issue that is footnoted but in fact has no mention of my topic, wasting easily 8 minutes of my time per instance. For this, historian Scott L. Bottles, I hope you die (despite saving me all that other time). Wait, just checked and the book was written in 1954. So I guess you probably are dead anyway, Bottles.
Editor's Note: thanks to Tom Lehman for a key revision.
