Charles Schulz had always resisted republication of the earliest "Peanuts" strips, as they did not reflect the characters as he eventually developed them. However, in 1997 he began talks with Fantagraphics Books to have the entire run of the strip, which would end up with 17,897 strips in total, published chronologically in book form. In addition to the post-millennium "Peanuts" publications are BOOM! Studios restyling of the comics and activity books, and "First Appearances" series. Its content is produced by Peanuts Studio, subsequently an arm of Peanuts Worldwide LLC.
