Note that the output is meant for manual editing afterwards, since Douban does not provide revision and publisher location.

For example, there are two issues in the above example:

The Little Schemer - 4th Edition[M]. should be:

The Little Schemer[M]. 4th Edition.

And Th: The MIT Press. should be:

Cambridge, MA: MIT Press

(Th is a silly guess, which may be useful for some Chinese publishers.)
