* Here we introduce the Extracted Features functionality (currently under beta release) that have recently been developed by the HathiTrust Research Center. This functionality is one of the ways in which users of the HathiTrust Research Center can perform non-consumptive analysis of subsets of the HathiTrust Digital Library's corpus that they have custom-selected by means of the workset mechanism available through the HTRC. (Currently, this functionality is available only for the HathiTrust Digital Library's public domain corpus, consisting of slightly less than 5 million volumes.)
...
Other ways of creating worksets, or of making use of public worksets created by other users, also exist. For example, if you already have a comma-separated values (CSV) file that specifies the list of HathiTrust volumeIDs corresponding to the volumes that you want your workset to comprise, you can simply upload it using the "Upload workset" link. For more information about creating, uploading and browsing worksets, you can consult the instructions available at the HTRC Wiki.
Click on 'Create Workset'.

By default, VM starts in maintenance mode where you can have network access. To switch to secure mode, you can hit the “Switch to Security” button. Once you perform the mode switch, within the VNC session, your screen is frozen in a short time. After that, you can resume your work. To switch from secure mode to maintenance mode, make sure you eject/unmount the secure volume before switching out of secure mode to ensure that any changes made to the secure volume are made permanent.
In the portal, go to "HTRC Data Capsule -> Show Virtual Machines" for the page for switching between modes. In the maintenance mode, click on the "Switch To Secure Mode" button in the portal to switch to the secure mode.
