Lefse is a larger category. Lompe (also called "potetlefse") is a kind of lefse. Lefse can also be made from wheat, and there are different kinds. A lot of types of lefser are also eaten as a snack rather than as part of a meal, with either a sweet paste or butter, sugar, and cinnamon on top.
I object to some of the information about the Norwegian hot dog. Firstly, lompe is not a tortilla: it's made from potatoes. (You also roll it all the way around the sausage.) The sausages are either shorter hot dogs or wieners. They are usually eaten with ketchup, mustard, onion (raw or roasted), and usually some sort of dressing. Simple and good.
The short text at the back of the book/cover that is usually a summary of what the book is about, I believe. Also often had some short reviews, like the op title refers to. (The stuff you look at when you are deciding if you want to read the book or not, generally.)
It's equally, or more, correct to say "female/male people". It's just like "poor people" is ok, but "the poors" makes you sound like an asshat. Including "people" makes the difference.
