17 November 2022: WebCSD now supports 3D substructure searching by sketch. 3D searching can be performed, for example to specify a bond length, angle, or geometric constraints, using WebCSD's sketcher tool. More information is available here.

10 November 2022: Users can now export sets of up to 20,000 results records (not full text), up to 10 times per day, from UNL’s subscribed databases on the ProQuest platform (with the exception of Avery Index to Architectural Periodicals). The “Export Results” option is only available if the total search results are 20,000 or less; to see it, users must have a My Research account on the platform and be logged into it. Exported results are made available for download in the Saved Searches section of My Research. 

28 November 2022: WRDS (Wharton Research Data Services) will implement two-factor authentication via Duo Security for logins to the WRDS website, as described here. Duo is already in use at UNL to authenticate logins to the university network. Users will be able to opt-in to two-factor authentication on WRDS beginning November 28th; it will be required for web logins beginning December 5th. 

16 December 2022: State Papers Online will migrate to a new interface on the Gale platform. The new interface can be previewed here

31 December 2022: The SciFinder Scholar interface will be retired on December 30, 2022. Access to the database will continue using the SciFinder-n interface. Saved answer sets and alerts must be migrated using the SciFinder-n interface prior to this date.


November 2022 (updated): Visual History Archive will migrate to a new interface in early November. Until then, the new interface can be previewed on a beta site. More information about the interface redesign is available on ProQuest's support site

13 September 2022: African American Periodicals (Readex) will migrate to an upgraded interface. All existing links will automatically redirect to the new interface.

9 September 2022: Checkpoint is scheduled to migrate to a new authentication system on Friday, September 9. Previously registered users will receive an email notification prompting them to supply their name and UNL email address. The email address provided in this step will be used for logging into Checkpoint and for receiving password reset links once the migration is completed. The current registration link should continue to be used for creation of new accounts. Further information is available in this FAQ document

8 September 2022: UNL users can now access O'Reilly Online Learning using their UNL login credentials, at Each individual user will have a personal account; all accounts display the generic user name “University of Nebraska Lincoln Learner”. 

Users who have saved information (for example, playlists) under their previous email-based account can still access these by entering their email address on the login page, then choosing the “Sign in with password” option. If you desire assistance from O’Reilly support in transferring a playlist from your old account to the new one, please contact

Links in the library catalog and A-Z Databases list will be updated to use this simplified authentication method on September 10, 2022.

8 September 2022: ICPSR has discontinued support for remote (off-campus) registration of new user accounts on the basis of email addresses. There are now three options for creating new ICPSR accounts: 

  1. Register on the ICPSR site from a computer on campus.  

  1. Register on the ICPSR site from an off-campus computer, then email from a UNL email address to request validation. This option is only available during business hours (Eastern Time zone). 

  1. Register from an off-campus computer using this link (proxied), then use this link (unproxied) to access the ICPSR site and log in. The ICPSR website does not support access via proxy servers, except for account creation.
