What is the Web Scrapbook?
Think of it as a clipping file for the Internet. Into that file you can place images, excerpts, and whole web pages that you find while you surf the web or that reside on your computer. In addition, you can annotate these items, sort them into folders, and add memos to those folders. Unlike a bookmarks file or favorites list that is stored by your web browser on your computer’s hard drive, you can access items you save to the Web Scrapbook from any computer connected to the Internet.
In addition, the Web Scrapbook is a collaborative environment. You can grant other Web Scrapbook users access to any folder you choose, and allow them to annotate, comment upon, copy, move, and delete items within those folders. They can also add items to those folders if you give them permission.
Using the Web Scrapbook, a class working on a project together could place all of the items they wish to discuss or annotate into one shared folder. Groups with a common interest could collaboratively build, sort, and annotate a list of relevant web pages, images, and passages.
Scribe New! Scribe 3.5 is available:
Scribe is a free cross-platform note-taking program designed especially with historians in mind. Think of it as the next step in the evolution of traditional 3×5 note cards. Scribe allows you to manage your research notes, quotes, thoughts, contacts, published and archival sources, digital images, outlines, timelines, and glossary entries. You can create, organize, index, search, link, and cross-reference your note and source cards. You can assemble, print, and export bibliographies, copy formatted references to clipboard, and import sources from online catalogs. You can store entire articles, add extended comments on each card in a separate field, and find and highlight a particular word within a note or article. Scribe’s uses range from an undergraduate history research seminar to a major archival research project.
