4. Crosswords were looked down upon by the New York Public Library due to people running to dictionaries and encyclopedias for crossword references in the 1920s. The NYPL thought that those crazed puzzle ‘fans’ were driving away readers and students who needed those books in their daily work, while the Library questioned their duty to protect their legitimate readers and researchers. Of course, cut to present day and you’re likely to see more people sitting in a library with an open laptop other than a crossword puzzle, but those rare sightings are probable and welcome to many nostalgia lovers.
