• Opera
  Opera in its latest version 7.11 is not only the sleekest browser currently on the market. It also has an indispensable feature for archiving data from the internet: When you save a web pages with images (Menu File -> Save with images as …), Opera adds automatically the URL from which you saved the document as a remark into the HTML source code. This feature makes referencing the document at a later stage of the research process much easier.
• Internet Explorer
  The overwhelming majority of Internet users currently uses Microsoft's Internet Explorer to render web documents. As the interpretation of news at times also requires the interpretation of visualizations, it is therefore imperative to keep a copy of the most popular browser software handy. Note, however, that even identical versions of Internet Explorer or any other browser for that matter necessarily renders identical visualizations of HTML documents, as each user can customize both browser software and desktop properties. As most users use default options, the rendering of web pages with default options, will normally give you a reasonable idea, on how the average user will access a document.
• Missiontrek Cartagio
  If you rely heavily on web data, you might want to consider Cartagio as your collection tool. Cartagio helps you organize and re-track the data you collected from the web. Cartagio's interface is little cumbersome to learn, and, unlike other browsers, Cartagio is not free (prices start at US-$ 75), but in the long run the ease with which you can store and organize data may well offset your initial investments.

• Net Snippets
  Net Snippets is not quite as powerful as Cartagio in its ability to organize data from the web. It can, however, help to collect and organize quotations from web pages, if you are are using Internet Explorer, for which it is a plug-in.  Its hefty price of US-$ 79 does not seem in tune with the offer made by the far more powerful Cartagio or the similarly equipped, but less expensive SnipIE.
• SnipIE
  The now defunct SnipIE was another plug-in for Internet Explorer. It allowed you to save and organize text clippings from web pages, automatically saving URI and referring URL. At US-$ 22.50, it is considerably cheaper than Net Snippets.
