GPO Access offers a variety of formats for viewing documents. The main format types are ASCII text and Adobe Acrobat Portable Document Format (PDF). Hypertext Markup Language (HTML) and Text Image File Format (TIFF) files are also available for some documents.
Not all file formats are available for each database.
ASCII text documents contain only the raw data and no formatting. As a result, they do not have any special graphics or font formats, such as bold, underline, or italics. When graphics and other elements are omitted or represented differently as text, a statement to that effect is included in double angle brackets (e.g., <<NOTE:>>) within the document.
Documents in the Adobe Acrobat Portable Document Format (PDF) preserve a printed document's original appearance. Their high aesthetic quality is achieved through the use of text, graphics, photos, and color. This format provides full-text search capabilities, allowing you to search and retrieve exactly what you need. It is independent of computer platform or distribution media and is available to all users who have the free Adobe Acrobat Reader Software. Users with SWAIS access will be unable to retrieve PDF files.
A Hypertext Markup Language (HTML) file is the document that a Web browser receives from a Hypertext Transfer Protocol (HTTP) server. It is an ASCII text file with tags that signal how the browser should display the contents. HTML documents can be presented with formatting, graphics, and links.
A Text Image File Format (TIFF) is a graphics file. It is essentially a screen-shot of a document that contains both text and graphics; therefore, it is not searchable. To view a TIFF file, you must have a graphics viewer associated with your Web browser. TIFF files are found mainly in the older documents on GPO Access. A TIFF file differs from a PDF file in that it preserves the original appearance of a document but is not searchable.
