Sometimes a page, or set of pages, is useful outside the context of surfing the Web. For example, your site might offer a tutorial or F.A.Q. that people might want to read when they're not online.
This problem can sometimes be mitigated by creating a page of the Appropriate Length that can be downloaded. However, if the content spans several pages, or is a single page with many images, downloading becomes a chore.
Therefore, if you anticipate that a page or pages will be useful offline, offer an archive file that contains the entire 'weblet' in an easily downloadable form.
Creating a downloadable weblet requires an approach slightly different from creating normal Web pages. Offline Readability is a must, as are Readable Links. If the weblet spans multiple pages, then links between them should be Relative Links so that they will work when viewed offline.
