"Place" in what way? As a download or as visible content?
First off, do not consider embedding .doc or .pdf files into web pages: include the text in your markup in the usual manner or make it available as a file download. Secondly, text-based files should always by in either a plain text format (.txt) or a Portable Document Format (.pdf). The provide a link to the download location of a good PDF reader such as Foxit for the convenience of your visitors.
