Frequently Asked Questions

Contact Ask Us at if you have questions.

Q: Why can’t I access Scifinder-n when I’m off-campus, even when I navigate through the library’s website?

A: The settings for the library’s proxy server were not set up properly. As of Feb. 25, 2020, they have been corrected, and you should be able to remotely access Scifinder-n. 


Q: I can’t get remote access to Scifinder Scholar or Scifinder-n while using the VPN browser or AnyConnect – why? 

A: In the past, the library’s helpdesk had encouraged users to try the VPN browser as a workaround for remote access to the library’s electronic resources when the proxy server was not working. Over the past two years, the helpdesk has changed that approach and is encouraging all users to navigate through the library’s homepage to access an electronic resource, and then authenticate through the proxy server, because the VPN environment does not work with all of our resources. This is especially true of the Scifinder products because they require two levels of authentication. Our helpdesk also tells me that the Scifinder products will definitely not work in the VPN AnyConnect environment. 


Q: Does Scifinder-n link from the records for references, structures, and reactions to any important protein or crystal structure databases?

A: No, Scifinder-n does not link out to other sequence or structure databases at this time, but I would be happy to pass on any database suggestions you have to the Scifinder representative.


Q: Does Scifinder-n have a structure similarity search like Scfinder Scholar did?

A: Yes, Scifinder-n has the same search. Do a Substance search using a structure. In the search results, look at the top left for the Structure Match section. Select the Similarity results to see the structures and Similarity scores. Visit Scifinder-n Help: Filter by Structure Match for details.


Q: Can I migrate my saved files from Sciplanner in Scifinder Scholar over to my account in Scifinder-n?

A; No, because Sciplanner does not exist in Scifinder-n, nor will the feature be added in the future. The only items that can be migrated are: saved reference answer sets, saved substance answer sets, and KMP alerts. You can download your Sciplanner files to your own computer by selecting the Workspace tab in Sciplanner, and then Export. You’ll want to export the files before Scifinder Scholar is discontinued at UNT at the end of August 2020.


Q: How do we know which journals are indexed in Scifinder-n?

A: CASSI (CAS Source Index) is the online record of all journals, conference proceedings, and technical publications indexed in Scifinder-n. If you’re wondering if a journal is included in Scifinder-n, enter some words from the title or the title’s abbreviation and you’ll see the possible matching entries. The entry should also tell you the years of the journal included in Scifinder-n.


Q: Is Scifinder-n going to have a mobile interface?

A: No, there are no plans to develop a mobile interface; however, you should have full functionality using the website on your phone.
