Some people actually make a living previewing and rating software downloads.
I have looked at each one of these programs, use several of them in my own work, and am happy to pass on the information to you. I don't have the time to keep track of shareware, trial editions, and so forth. However, I have much respect for the Shareware concept to the extent that I wish its principles would find their way more deeply into Catholic resource publishing. FREE software exists primarily to introduce people to the commercial-use versions of the same product. The software listed is downloadable through a link ONLY if its name is in underlined text.
