Bibblio lets you collate and curate a range of web based content related to a specific subject and present it in a logical manner as a collection.As well as creating your own collections you can also access a range of existing collections created by other users.
I could see this be an invaluable tool for both students and teachers in allowing them either to pull together their own collections as a way of capturing their research sources or as a way accessing information related their topic of study.
Here is an example of an existing collection
Collections allow you to provide a description outlining what it is about. Collections can be tagged making easier for others to find, collections can also be shared via, Facebook, Google+, Twitter and Linkedin using a unique url.
As with a lot of these sites you can log in with either your Google or Facebook account meaning you don't need to remember yet another log in.
