Data Management Toolkit @ UNH

This toolkit provides information to help researchers develop data management plans and effectively manage their research data.

Requesting a DOI

DOIs are used for a variety of content types including reports, datasets, supplementary materials, images, and other scholarly and research outputs. As a member of the University of New Hampshire, you can request a DOI through the UNH Library for your scholarly and research outputs. Your DOI will resolve to a landing page in the UNH Scholars’ Repository, which will either provide direct access to the content, a stable link to where users can access the content, or descriptive metadata that identifies the content and its location.


Request a DOI button

To learn more or to request a DOI, contact our Institutional Repository Coordinator. We will ask you to complete a simple form with basic information about your content and submit a copy of your content or a stable link to your content. If you or your group request a large number of DOIs in a fiscal year for a special project, please contact us so we can negotiate a cost-share with you.

Digital Object Identifiers

DOIs are persistent unique identifiers designed for research objects, such as articles, books and book chapters, conference proceedings, data sets, etc. The DOI system is designed to identify objects (or metadata for those objects) wherever they are located on the web, unlike a URL which points to a specific location on the web which may change or disappear over time. With DOIs, dead links should not happen.

DOIs are typically issued at the time of an object's publication, much like an ISBN or serial number. All DOIs begin with a 10 and contain a prefix and a suffix separated by a slash. The prefix is a unique number of four or more digits assigned to organizations; the suffix is assigned by the publisher and identifies the object.

Anatomy of a digital object identifier

Why use a DOI for your scholarly and research outputs?

  • Aid in citation tracking, ensuring a researcher has accurate metrics on how and where their research outputs are being used or referenced. 
  • Increase data sharing and reuse, by making information discoverable over the long-term. 
  • Are required or strongly encouraged in certain citation style guidelines.
  • Are becoming a required part of repository, journal, and database submission workflows. 

DOIs for Alternative Citation and Metrics Tracking

Tracking an article's metrics helps researchers measure the impact of their work and the number of times it is cited, discussed, shared, bookmarked, or otherwise used across the Internet. Published materials such as reports, grey literature, datasets, and other outputs that are not published via traditional scholarly mechanisms are often difficult to track and so some metric tools won’t always provide a full picture of where or how they are being used. DOIs can help with this!

Beyond ensuring continued access to scholarly outputs, DOIs offer the benefit of being traceable across the web, which allows metrics of published material's success to be tracked over time. Alternative metrics or altmetrics aim at capturing success through additional means that citation counts, including article mentions on Twitter, the number of times an article is publicly bookmarked or saved to a citation manager, etc.

The best way to ensure that altmetrics can be collected for an object is to place it in a repository that already has tools in place to track altmetric data, but there are other services that can help gather altmetrics. 

  • Altmetric it! allows anyone to easily get altmetric results for a published object by adding the free Altmetric it! bookmarklet to a browser's bookmarks toolbar. After adding the bookmarklet an individual will simply need to click the link while viewing an object to get its altmetrics. However, the bookmarklet only works on PubMed, arXiv or pages containing a DOI with Google Scholar friendly citation metadata and Twitter mentions are only available for articles published since July 2011.
  • Paperbuzz is “a free and open way to track the online buzz around scholarly articles.” A user searches using a DOI and then Paperbuzz generates a report for references found on the internet. The main issue with Paperbuzz is that its data isn’t complete for objects published before 2017, thus greatly limiting its effectiveness but you can get alerts for future article mentions when they occur.
  • PlumX “Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment.” PlumX is broken down into five categories: citations, usage, captures, mentions, and social media. PlumX is designed for journals, repositories, data providers, and platform partners, not individual users. The UNH Scholars' Repository uses PlumX and allows users to easily see the altmetrics for their content on the side bar when viewing it in the repository.
  • Google Scholar Citation Profile is a simple way to track both a single object's metrics, and a researcher’s complete bibliography. Google Scholar Citations tracks total citations, as well as a researcher's h-index and i10-index, which can be further broken down by year.
