And that is exactly what you have found, a place where you can download public domain comics in English and download them. You can also use the Preview feature to read part of a book to decide if you want to download it. Many books are anthologies, which feature a variety of genres, and many books feature a single kind of stories. Marvel, DC, and comics featuring Disney characters are not available here, that material not being in the public domain. The most recent issues are from 1959. Most books are American, with a comparative handful from Canada and England; all books are in English.
Good to have you here, and feel free to ask questions.
