Baen makes available (for free) the amazing story by David Brin - Shoresteading.
It's divided in 2 parts, though, 1st part is
here, 2nd part
here. It's in online html, so you have to download the page and do a little editing before you can read it on your reader.
Ah, while speaking of Baen, Jim Baen's Universe vol 3 number 5 is out, too and can be found
here. The TOC looks very promising indeed.
