There are many editions of Main Street. This educational edition was created for self-improvement or in preparation for advanced examinations. The bottom of each page is annotated with a mini-thesaurus of uncommon words highlighted in the text, including synonyms and antonyms. Designed for school districts, educators, and students seeking to maximize performance on standardized tests, Webster’s paperbacks take advantage of the fact that classics are frequently assigned readings. A running thesaurus at the bottom of each page is useful to students who are actively building their vocabularies in anticipation of taking PSAT®, SAT®, AP® (Advanced Placement®), GRE®, LSAT®, GMAT® or similar examinations.
