Some of the features that are available from Thought Ark are:
- Store and share collection of saved bibliographic searches.
- Value resources based on usage
- Paper writing and citing interface
- Paper publishing
- Comments on resources and published papers
Developed by a team comprised of students from Purdue University's TLT department along with Dr. Sonrin Matei, Thought Ark is an open source "free" utility to allows you to determine bibliographic resources through a collaborative space that also gives you the ability to identify resources you search for and those of others whose searches are similar and provide you the opportunity to utilize their results.
Now some unfortunate news, even though you can go directly to the site and use it just like any other search engine, you have to create a login to store your search results and to use some of the advanced features of the site. Once you create your login, I would suggest making it something that you are use to, then you have the ability to save and share resources, as well as to create Classes and Papers that you post onto the site.
