It’s not in the Midwest. St. John’s College is where I did my graduate work. They are phenomenal. They have 2 campuses: one in Annapolis, Maryland, and the other in Santa Fe, New Mexico. They use what’s called the Great Works Curriculum. You study primary texts, and sometimes in the original language. They have the highest per capita rate of students going on to higher degrees of all colleges in the US.
@Acrylic Any of the above mentioned should give you a good liberal arts education, preparatory to getting an MLS. You want recommendations in the midwest but I’ll just mention that I went to Sarah Lawrence College in Ne York state and got a great education there (and then an MLS.)
