If much of the information you need to keep track of is located in websites, you can use a browser-based reference manager like Zotero to bookmark or take digital snapshots of websites. Zotero will also allow you to annotate, tag, organize, and search your collection, and create references to websites that can be formally cited in a research paper.
The browser-based HP Smart Web Printing tool is similarly designed to let you clip selections from webpages and integrate them into a single scrapbook-like document for either direct printing or conversion to a PDF.
