Book, magazine and newspaper publishers spend a lot of their time buying or commissioning copy; newspaper publishers, by contrast, usually hire their own staff to produce copy, although they may also employ freelance journalists, called stringers. At a small press, it is possible to survive by relying entirely on commissioned material. But as activity increases, the need for works may outstrip the publisher's established circle of writers.
The browser attempts to fetch pages from servers while only in the online state. In the offline state, users can perform offline browsing, where pages can be browsed using local copies of those pages that have previously been downloaded while in the online state. This can be useful when the computer is offline and connection to the Internet is impossible or undesirable. The pages are downloaded either implicitly into the web browser's own cache as a result of prior online browsing by the user or explicitly by a browser configured to keep local copies of certain web pages, which are updated when the browser is in the online state, either by checking that the local copies are up-to-date at regular intervals or by checking that the local copies are up-to-date whenever the browser is switched to the online state. One such web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer.
