Translated from the original Swedish.
A wide array of books, mostly novels, are each condensed into four comic panels on a single 5×7 page. The artwork is reasonable, and the lettering is mostly easy to read. The only written information given on each book is the title, original year of publication, and author name (with years of birth and death).
I have read 18 of the 90, and am familiar with another 18. Based on that sample size, I would say that the author does a pretty good job of distilling each book into the requisite four panels. I am pretty sure that this work is meant to be more funny than informative, but in my opinion, it was equal amounts of both. I found very few to be laugh-out-loud hilarious. Even so, it was a fun 35 minutes.
Rated: Moderate. A dozen uses of mild to moderate terms, and no lewd artwork.
