When working on a research project, putting together a collection is a great way to organize helpful resources. Not only can you create your own collections for private or public use, you can also view public collections created by other HathiTrust members.
In the tool bar at the top of the page, there are two tabs that relate to collections. Under "My Collections," you can create a new collection or view collections that you have already saved. Under "Collections," you can search other researchers' collections.
When you create a new collection, you will be asked to give it a name. There is also a space for adding a description of the collection. You can make the collection private—viewable only to you—or public, to share with other HathiTrust researchers.
For demonstration purposes, I have created a collection called "The U.S. Civil War." The title becomes a hyperlink, which can be used to access an individual collection.
From within the collection's page itself, you can move items from another researchers' public collection, from another of your own collections, or search HathiTrust for new items to add to your collection.
Another way to add items to your collection is from your search results page. Here, I've run a generic search for "U.S. Civil War." After I have selected items via the check boxes next to the titles, I can use the drop down menu at the top of the page to add it to an existing collection, or start a new collection from here.
