Comrade Physioprof opines, in the comments to my last, that I have "an illness."
Oh, yes, I do, but it's not what he thinks.
Organizing one's books in LC order is a minor eccentricity for an English professor (and visit the Little Professor's blog, say here, for an example of someone who has more books than I do); among librarians, I'm sure it's considered a professional hazard at worst, and probably a sign that you really love your job.
However, staying up three hours past bedtime to pore over snippets of excruciatingly illegible secretary hand (see here for an example) in an effort to decide whether any of them were written by the same chap who signed his name on a flyleaf, and if so how many, and whether the marginalia with very similar letter forms but with a different slant should be assigned to the same chap or assumed to be from a different writer . . . that's sick.
I can grant that, but I still think people with food blogs are weird.
