These are Some Useful Tools for Search, and for Research

• Archive.org is an amazing repository of of TONS of STUFF. Things you didn't know should be recorded & cataloged... it's here.
• Diigo is a researcher's dream. You'll never need 3x5 notecards again! In researching a topic you can highlight bits of text or images on source webpages, take screen shots, add your own post-it notes... stay organized by not just keeping bookmarks, but the bits of import that you would normally have to write down in an online library! organize these bits into folders or share-able groups, add tags for ease of recall. Diigo also has a social media component wherein you can tag resources for group activity sharing, and even"follow" other researchers. all while embedding the tools right into your web browser (see Chrome store, etc.). Awesome!
• Did your research, found info, now what? MyBib is a website (and App) that magically transforms your Internet resource URLs into MLA formatted Bibliography entries. You can easily edit to improve the citation, and then save or export the entire list of references (format and all) directly to your Google documents, print as a Microsoft Word doc, or several other choices. It's not just for URLs. They list DOZENS of distinct source categories. and with a paid account you can have your citation formatted for APA or Chicago/Turabian styles.
• InstaGrok.com Great for visual learners, this website is a search tool that shows results graphically, and then allows you to explore those "branches" of related results. You can also add your own notes, and they also give you links directly to the info found for you, making evaluation of sources easier. Plus your "Grok" can be shared and much more.
• OneTab is a browser tool for Chrome or Firefox that I use daily. Tired of having 26 browser tabs open at once? OneTab is a tool that lets you collapse all the tabs into one sheet that you can click on to re-open, or save as a webpage, or lock (as your favorites) so they are always right at hand. On screen but not in the way, and sharable, editable, etc. Nice!
• WordSift.com is a useful tool for drawing out important vocabulary from a piece of writing. It is a benefit for anyone, but probably most valuable to English learners /ESL and others introduced to new vocab. Just copy and paste a block of text (a magazine article or blog post, for example) and WordSift does the rest. Created by Stanford University, the sifted results can be organized alphabetically or by degree of rarity, and you can focus in on words that pertain to one subject such as mathematics or science vocab found in the sample text.
