Office itself ships with a large selection of TrueType fonts, as do many other programs like CorelDraw. These are not always installed by default, so either check your installation CDs for font files or re-run setup and check the available options for fonts.
Google can help you find fonts
There are lots of free or commercial fonts on the net. Quality vendors include (but are by no means limited to) Adobe, Linotype, FontHaus, ITC, Agfa, and Bitstream.
