Free fiction: A few pulp magazines

All at Internet Archive in multiple formats:

1. Dynamic Science Fiction: January 1954 (download).
2. Wonder Stories: August 1934 (download).
3. Planet Stories: Summer 1949 (download), November 1950 (download), Spring 1955 (download).
   
   November 1950 issue includes a Mitky Mouse story of Fredric Brown. Not the lovely original, though - it appears to be a sequel.
4. Super Science Stories: May 1940 (download), January 1941 (download).
   
   January 1941 issue has PDF of nearly 100 MB; I've not checked other formats. All other issues have PDF of reasonable size.
