Most of the files are PDF documents. PDF stands for Portable Document Format.
Adobe provides a free reader to browse and print these files.
PDF format keeps the documents in their original form and font. Any computer with a PDF reader can pull up a document and it will look (and print) the same as the original.
Word processor files that have been converted to PDF documents (such as the local rules) can also be searched, cut and pasted, and it is possible to create links within the document. For example, the index of the local rules are links to those areas within the document. Also, because all the local rules are in one file, a person can use the PDF reader to search the entire rules for a word or phrase.
Most forms are WordPerfect files that were converted to PDF documents. Some forms are scanned images of the original form and then converted to PDF. The PDF document is smaller than the corresponding graphics file, and when printed, looks just like the original. The PDF document will download faster than the graphics file because of its smaller size. Scanned files cannot be searched.
