DC Linktank
"Linktank is for students, professionals, and lifelong learners."
It's no wonder why Promethean Professionals chose to highlight DC Linktank. Shamelessly stolen from the Linktank web header, their motto correlates perfectly with our goal: providing tools and information to the lifelong learner. Bear in mind this site is most beneficial for residents of the DC area.
The site itself is fairly easy to navigate, as the soonest approaching events are listed on the main page. From here you can sort out the fields of your interest by geographical region, national or international, business or public policy, you name it. At the time of this writing some prominent events include An Armchair Conversation with Ruslana Lyzhychko from the Center for Strategic and International Studies (CSIS), Destroying Syria's Chemical Weapons: One Year Later, and one I am personally excited about Georgetown University's Financial Markets Quality Conference.
Many of the events are free and all of them provide a unique insight into what global administration and private industry leaders are actually doing in the modern world. You do need to register for DC Linktank, but let's face it, between all of your social media accounts, school and/or work you can adhere to another username and password in for the sake of your future career. So if International Studies, Political Science, Business or Economics suit your fancy or even if they don't we can guarantee you can find an interesting event at DC Linktank.
Project Gutenberg
A vital tool for anyone needing quick access to (typically) older books without needing to pay out of pocket, Project Gutenberg (named after the Gutenberg Printing Press) is the first and one of the most well-known producer of free online E-Books.
Free books? That must be illegal!
Because many literary classics either do not have a copyright or the copyright has expired in the US (and other countries; be sure to check with your country's copyright laws before consuming or redistributing material from Project Gutenberg) they can be uploaded or downloaded at will free of charge. As of now, Project Gutenberg hosts over 45,000 digital books that can be downloaded for later, read on the web, or saved to your Kindle. A resource I wish I had in my high school English classes having to read "The Tale of Two Cities" or one of my favorites Mary Shelley's "Frankenstein" or "The Modern Prometheus".
Project Gutenberg also facilitates self-publishing for contemporary authors and has affiliates to other E-Book resources, Audio books and digitized sheet music.
A paragon of Promethean Professional vision, Project Gutenberg is a severely priceless tool for the professional in the making or anyone who just wants a good book to read. If you like what they're doing, consider donating to help them continue their noble services.
Textbook Rentals
Simply stated (which is frankly more than what needs to be stated) Textbookrentals.com is a great place to rent textbooks.
Revolutionary.
But the reason textbookrentals.com gets the Promethean Stamp of Approval (patent pending) is because it compares many if not all of the best options for students looking to buy or rent textbooks. Used or New, Amazon, Chegg, Knetbooks, BookRenter, eCampus, One semester, 90 days, 60 days, Rented or Purchased, Textbook rentals compares all of your options when buying costly college texts and helps you save as much as possible by comparing all of your options in an easy "click and compare" set up.
For example, my University Book Store lists "Economics of Money, Banking, and Financial Markets, 10th Edition" by Frederic Mishkin at $233.93 for a used copy. When using Textbook Rentals and comparing it with the lowest bidding rental websites I can rent the textbook for as little as $47.48/semester from Chegg or even buy it new for $53.15 from AbeBooks. That's as much as 80% savings one just one book! Textbook rentals only lists the most trusted retailers and renters of textbooks so you don't need to worry about seedy transactions and shady fees. In my experience thus far, Textbook Rentals is the easiest and most streamlined way to make your money go as far as it can for college texts. You don't need to register and it's completely free so make sure to consider textbookrentals.com for your next textbook purchase.
