Long before I moved up to Portland, I worked at a medical college library back home and would spend the slower nights diagnosing my ex-girlfriends with the DSM-IV (and I completely NAILED the diagnosis of one ex having BPD). Other nights I would look through emergency medical texts and books on trauma, which only prepared me for marathons of Bones, Wire in the Blood and Shark Week.
Now, I use the library’s unlimited resources for good and less morbid things. Like cheese. Wonderful, joyful cheese. One little gem that I recently found at the Portland Public Library was this USDA published guide, from 1967, on buying cheddar cheese.

Glad to see the USDA is staying current on these things.
Glad the PPL is keeping current too. Then again, my Dept of Agriculture books on canning, from the 70s, are still quite useful and accurate 🙂
Well, their archives are current as this is where the pamphlet was found. They have a huge section in the downstairs area of government documents and this was part of it.
