Contribute a Resource or Collection

NSDL encourages developers of STEM content, NSF grant awardees, STEM educators and learners, and all other NSDL users and community members to contribute individual resources or collections of resources to the Library. We welcome recommendations concerning digital resources NSDL users have created or discovered on the web, such as activities, lesson plans, web sites, or simulations.

We are also eager to hear from organizations or individuals who have created or are interested in creating collections of STEM resources. In NSDL terms, a resource collection is an assemblage of related digital resources—usually brought together around a topic or theme, type of resource, audience, or institution—each with its own URL, and each catalogued by the collection builder or manager. NSDL also accepts annotation collections and usage data (paradata) collections. These collections are comments, ratings or usage information attached to resources existing in the NSDL.

Benefits of contributing materials to NSDL include:

  • Exposure. NSDL marketing and outreach activities promote access to resources and collections
  • Discovery. NSDL search and browse mechanisms enable users to locate appropriate collections and resources
  • Service. Making materials available through NSDL encourages sharing and reuse of resources within STEM education and research communities
  • Support. Access to technical assistance and tools for collection development and management are available from NSDL
  • Recognition. NSDL clearly attributes collections and the resources within them to their providers

There are two methods for contributing materials to NSDL, described below. Which method you use depends on the number of resources you wish to contribute, and whether they constitute a collection.

1. Contributing one or several individual resources

This is quick and easy to do. The steps are as follows:

  • Ask yourself whether the resource is appropriate for NSDL. Does it support teaching and learning (not research) in science, technology, engineering, or mathematics, or educational research? Is it scientifically sound, technologically reliable, and easy to use? Refer to these documents for additional guidance:

  • Complete the Recommend a Resource form, providing the URL to the resource and descriptive information about it.

If your recommended resource is accepted, the information you provided may be edited and the resource will become part of the library. Recommended resource reviews are completed on a quarterly basis .

2. Contributing a collection

As mentioned above, NSDL uses the term collection to designate a group of digital resources that have something in common—a shared topic, intended audience, genre, resource type (e.g., demonstrations, videos), the institution that has sponsored their creation or review, or another shared characteristic. Each resource in a collection has its own URL and has been, or can be, individually catalogued. Examples of collections include the COMET Program Collection and the DragonflyTV collection. If you are interested in creating a collection for inclusion in NSDL, see Collection Development Strategies.

Contributing an existing collection to NSDL involves working with us to enable NSDL users to discover and get to individual resources in the overall library collection via a search across all the multiple collections that comprise NSDL.

Achieving this goal takes time and effort—the collection you are building must have the capacity to provide us with NSDL-compatible descriptive information (or metadata) about each of its resources.

The tasks involved in contributing a collection to NSDL are outlined below. They may be accomplished in various orders or in parallel.

  • Ask yourself what type of collection you would like to contribute (resource, annotation or usage data). Are you providing resources for teaching and learning? This is a resource collection. Are you providing resources that include teaching tips, comments from teachers or other users, educational standards, star ratings? This is an annotation collection. Are you providing resources that indicate how many times a resource was downloaded or favorited? This is a usage data (paradata) collection.

  • Ask yourself whether your collection is appropriate for NSDL. Do resources in your collection—or a significant portion of them —support teaching, learning, or educational research in science, technology, engineering, or mathematics (STEM) topics, or in use of digital learning objects? Are they scientifically sound, technologically reliable, and easy to use? (See the NSDL Collection Policy and the NSDL Resource Quality checklist, and other NSDL quality rubrics). Do the annotation and usage data you provided apply to resources already existing within the NSDL? If you believe so, please contact us to initiate a discussion about next steps.

  • Consider the descriptive information (metadata) you have about individual resources (items) in your collection, or your capacity to create such metadata. The NSDL_DC Metadata Guidelines provide a review of what metadata is, how it works in NSDL, and how it can be shared with NSDL. The NSDL_DC Metadata Guidelines also provide information, definitions and controlled vocabularies specific to creating the NSDL_DC format.

    • Other metadata formats can be submitted to NSDL. However, NSDL needs to work closely with metadata providers when their metadata format is unknown to NSDL (this is because some NSDL services require the NSDL_DC format).
    • Collection builders may use other metadata formats that are known to NSDL and are supported in some cataloging tools. The list of known metadata formats includes MSP2.
    • If you need to create metadata, there are cataloging tools available within the NSDL community, including the Collection Workflow Integration System (CWIS) and the NSDL Collection System (NCS). To learn more about either of these tools or to discuss providing a new metadata format to NSDL, please contact us.

  • Provide NSDL with metadata about your resources. Contributing a collection to NSDL means making your item-level metadata accessible to NSDL systems and users. Collection builders can share metadata with NSDL by: 1) using an Open Archives Initiative (OAI) server; 2) programmatic means, via an application programming interface (API); 3) by using a cataloging tool that talks directly to NSDL. See Sharing Metadata with NSDL for more help in understanding these distinctions.

  • Register your collection with NSDL. Do this by contacting us. You will need to provide general overall information about your collection, as well as contact information.
  • Provide a collection brand or logo. This is a small digital image, 100 pixels wide by 30 pixels tall or in that ratio, that we will use in displaying items from your collection when they appear in NSDL search results. Please see our Collection Branding Guidelines for file format and other specifications.
  • Obtain NSDL Accessioning Board (NAB) approval. Per the Collection Policy, all collections are required to be approved before being accessioned into NSDL. This formal, yet simple check ensures resource and metadata appropriateness. The NSDL collection development team works with collection builders to walk you through the steps to gain this approval.
  • Maintain the collection. After a collection has been contributed to NSDL, it is our expectation that it will be kept up to date, with nonworking resource URLs weeded out and/or replaced, and metadata titles and descriptions corrected as needed, on an ongoing basis.
