Atrium Institutional Repository

What is the Atrium?

The Atrium is the University of Guelph’s open access institutional repository for scholarly and creative works. It provides long-term stewardship of scholarly and creative works created by the U of G community through the collection, curation, preservation, and dissemination of these works.

Please read our Digital Repositories Policy.

What are the benefits of depositing my work in the Atrium?

Some of the benefits of depositing your work in the Atrium include:

  • Your research publications will be free to read and easily discoverable for the benefit of society.
  • Most subscription journals, as opposed to fully open access journals, allow authors to self-archive their accepted manuscript in a repository after an embargo period (usually 12 months) - this is cost free alternative for making your work open access and meeting funding agency requirements. You can deposit your accepted manuscript as soon as the paper is published – it will automatically be made available after the embargo is lifted (if there is one).
  • Content in the Atrium is easily discoverable via major search engines including Google and Google Scholar. Content is described using metadata to enhance the ability of users to search for and discover materials.
  • Deposited items receive permanent URLs ensuring long-lasting reliable links to your work.
  • Compliance with open access funding requirements.
  • Content is safely and securely stored for long-term access.

Who can deposit in the Atrium?

The Atrium accepts submissions of scholarly or creative works created at or in collaboration with the University of Guelph. All University of Guelph community members including faculty, staff, students, and research collaborators are welcome to deposit in the Atrium.

Undergraduate student authors who wish to deposit non-thesis materials must have the approval of a departmental faculty member.

Can I deposit content on behalf of someone else?

To deposit content in the Atrium you must be either the creator of the submission, a researcher collaborating with the creator(s), or an individual designated by the creator of the submission.

If you are depositing content on behalf of your co-authors, you must seek permission from the other authors before submitting the work.

What types of content can be deposited in the Atrium?

The Atrium primarily hosts research publications and open access versions of scholarly and creative work such as:

  • Graduate theses and dissertations
  • Journal articles and preprints
  • Books / Book Chapters
  • Conference Presentations / Papers
  • Grey literature (including policy briefings, plain language summaries, trade publications, community outreach materials)
  • Other research outputs such as protocols, images, reports, infographics, papers, audio files, etc.

Can I deposit research data in the Atrium?

The Atrium primarily hosts research publications and creative works. Research data should be deposited in the University of Guelph Research Data Repositories. Visit How to deposit research data in the Agri-environmental Research Data Repository or the University of Guelph Research Data Repository for more details.

What do I need to consider prior to depositing content?


You are responsible for ensuring that the content you deposit in the Atrium does not infringe on the rights of publishers or any other entity or party. If your content has been commercially published, you must check your author agreement to see what rights you may have signed away during the publishing process and what rights you have retained. This will always be specific to each individual piece of work.


Depositing your work in the Atrium complies with the Tri-Agency Open Access Policy requirements for publications. However, if your work has been commercially published, you are responsible for ensuring that your publishing agreement and/or your publisher’s open access and self-archiving policies allow you to deposit the work in an institutional repository. Additionally, your publisher may have specific requirements for self-archiving such as which version of your work can be self-archived (e.g., preprint, accepted manuscript, publisher’s version of record) and under what conditions such as a temporary access embargo. For more information, please make a Publishing and Author Support Request.

Distribution rights

The University of Guelph will have the non-exclusive right to distribute your work freely and provide long-term access to it via the Atrium. You (or your publisher) will retain copyright to the work. Please see the Digital Repositories Policy (IV. Representations, Warranties, License) for more details.

End-user licensing

If you are the current copyright owner of the work, you can determine what others can do with it. During the deposit process, you will be able to apply a Creative Commons end-user license to your work to clearly indicate to others how they may use it. Please refer to the Use Creative Commons Licenses guide for more information.

Are there any deposit requirements?

You are responsible for ensuring the content you deposit in the Atrium aligns with preferred file formats, file naming conventions, and is accessible. You will also be required to provide descriptive information (metadata) about each item you deposit in the Atrium using the online submission form.

File format requirements

To promote reuse, interoperability, and long-term access, files should be deposited in open, non-proprietary file formats. Files should also be saved and stored in an uncompressed and unencrypted format.

For example, text documents, such as Word (DOCX) or PowerPoint (PPTX), should be converted to PDF/A format prior to upload.

If you are unsure about the long-term accessibility and readability of your file format(s), please make a Publishing and Author Support Request for assistance.

File naming requirements

When naming your files, please:

  • Keep the length of the file name short but descriptive (less than 25 characters).
  • Use date format ISO 8601: YYYYMMDD.
  • Use alphanumeric characters. Avoid special characters and accented characters.
  • Include a version number if applicable.
  • Use capitals and underscores instead of periods, hyphens, spaces, or slashes.

For example:

  • grizzlyStomachContent20201215.pdf
  • SmithJones_Sean_202012_MSc.pdf

File size limitations

Individual files must be equal to or less than two gigabytes (2 GB) in size for successful upload. There is no specific upper limit to the number of files or total overall storage size that can be added to a record or collection in the Atrium.

If individual files are larger than 2 GB or if you have a very large number of files to deposit, make a Publishing and Author Support Request for assistance.


Depositors are responsible for ensuring that all materials they deposit in the Atrium meet accessibility standards according to the Accessibility for Ontarians with Disabilities Act (AODA). Guidance and resources in support of creating accessible digital materials can be accessed through the Digital Accessibility Resource Centre.

You may also refer to the WebAim tutorials (Word, PowerPoint, PDF, Multimedia) for guidance on how to make your work accessible. Note that for textual documents, it is easier to modify the original format (e.g., Word or PowerPoint) than the PDF version.

Please note that not all content housed in Atrium is fully accessible. If you would like to request an alternate version of any content in the Atrium, please use the Library Resource Alternate-Format Request Form.
