36. Project Gutenberg With 20,000 e-books in its online catalog, Project Gutenberg is the place to download and read the classics for free. Of course, "classic" doesn't necessarily mean the kind of books you would read in a college literature class; on the day we visited, the top downloads for the past 30 days were the Kamasutra, Manual of Surgery, and Fifteen Thousand Useful Phrases.
37. RSS Publisher Create your own RSS feeds, podcasts, blogcasts, and more. It does not include ads, but it currently runs on Windows only.
38. SeaMonkey If you miss your old Netscape Communicator, this is the Internet package for you. Volunteers at Mozilla.org have updated the old browser, e-mail client, and HTML authoring tools with some of the best features from Firefox and Thunderbird. Like the radio stations say, it's the best of the 80s, 90s, and today.
39. 7-ZipIf you need to compress a large file, 7-Zip results in a smaller file than most other zip applications, including the popular WinZip. Plus, it unzips all of the common compression formats.
