Doyle, Arthur Conan, and Felix Sutton. 1957. Sherlock Holmes: a study in scarlet and the red-headed league. New York: Wonder Books.
Sobol, Donald J. 1963. Encyclopedia Brown, boy detective. New York: Scholastic Book Services.
Encyclopedia was a favorite growing up. He was easily the smartest of all kid detectives.
Herz, Peggy. 1977. Hardy Boys and Nancy Drew. New York. Scholastic Book Services.
Dann, David. 1977. Scooby-Doo and the Mystery of the Rider Without a Head. Newark, N.J.: Peter Pan Industries.
I do not have the record that came with this book, but it was digitized and put on YouTube.
Rathbone, Basil, Nigel Bruce, Patricia Morison, Arthur Conan Doyle, Leonard Lee, Frank Gruber, and Roy William Neill. 1985. Dressed to kill. Charlotte, NC: United American Video Corp.
Not a "juvenile" version of the Holmes character, but Basil Rathbone may be the most recognizable of all Sherlock Holmes actors, and these films were very accessible to young audiences on television and home video
Dubowski, Cathy East. 1996. The case of the Sea World adventure: a novelization. New York: Scholastic.
The Olsen Twins' Sea World outing aired on TV as I recall and it was enjoyable family special on ABC TV. It doesn't seem that any of the Mary-Kate & Ashley detective films be on DVD for a new generation anytime soon.
