To find books on a subject, you can do a keyword search or a subject search in the MERLIN catalog. You can also expand your search to all the academic libraries in Missouri by using the MOBIUS catalog, which you can expand to include Colorado libraries by clicking on the Prospector link. You can have materials from either catalog delivered to any of the MU libraries for pick-up.
Note that neither of these searches the full text of books, just a brief description. Google Book Search allows you to search within books that Google has digitized and in most cases preview a few pages. Usually a link in the left sidebar will then help you find the physical book in a library.
It can take several years for criticism to be published, so scholarship on very recent works may not appear in the research databases. Book reviews or blog posts may be the main responses to a work for the first few years.
Book reviews may be found in most of the databases listed. Look for the advanced search feature and the option to limit by document type to review or book review.
Database are very literal, so pay attention to the words you use to search. For example "clifi" probably won't retrieve "cli-fi". That hyphen makes all the difference!
