What is Google Scholar?

Google Scholar allows you to search broadly in the academic literature.   Google Scholar contains articles, theses, books, abstracts and court opinions, from academic publishers, professional societies, online repositories, universities and other web sites.

You should connect Google Scholar to Guelph databases by using our Google Scholar link or the video below so you will be searching Guelph databases when you search Google Scholar  

Benefits of Google Scholar:

• A simple search with the familiar Google box
• It's a great way to find an known article, i.e. an article for which you have a citation or at least some bibliographic information like the title
• It allows you to see how many times an article has been cited
• Searches freely-available open access material which might not appear in our databases

When you should use a database instead of Google Scholar:

• You need to limit by subject area
• You need to sort by date or relevance
• You need to ensure material is peer-reviewed

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

• Compliance with open access funding requirements.
• Your research publications will be free to read and easily discoverable.
• Most subscription journals allow authors to deposit their accepted manuscript in a repository after an embargo period (usually 12 months) - this is a 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.
• Content is safely and securely stored for long-term access.

How do I get started?

Please refer to our help pages for additional information about using the Atrium.

Professional Development Resources

MyGradSkills.ca is a resource for graduate students and postdoctoral fellows to enhance the professional skills so that they can succeed during their studies and research, and in a range of career paths. MyGradSkills.ca includes a number of self-paced, online modules on a range of #GradProSkills topics, including teaching & learning, to career development, to community engagement, to entrepreneurship, and much more. As the site expands, they also will be offering blogs, virtual career panels, an information clearinghouse, as well as additional online modules.

The Graduate Student Learning Initiative (GSLI) is a collaborative endeavour that brings together key campus services that support academic and professional skill development for graduate students as learners, instructors, researchers and professionals.

Mitacs is a national, not-for-profit organization that has designed and delivered research and training programs in Canada for 15 years. Working with 60 universities, thousands of companies, and both federal and provincial governments, they build partnerships that support industrial and social innovation in Canada. The Mitacs Step program is focused on four core competency areas in Professional Development. These are Leadership and Management, Communications and Relationship Building, Personal and Professional Management and Entrepreneurialism. The individual workshops in the Mitacs Step curriculum build skills in each of these competencies.

Search Archival & Special Collections' Archives Database

Welcome to the Archival & Special Collections’ archives database. Here, researchers can find descriptive information pertaining to collections in our holdings at McLaughlin Library, University of Guelph. Collections relate to the following subject areas:

• Agricultural history and rural heritage
• Culinary history
• Landscape architecture
• L.M. Montgomery
• Regional and early campus history
• Scottish studies
• Theatre history

Miscellaneous archival materials donated to Archival & Special Collections before the establishment of the above collecting areas are also included.

Researchers can browse our collections by using the Core Collecting Areas menu on the left-hand sidebar, or search by keyword using the search bar at the top of the page. Rare books and special collections can be found in the library’s online catalogue, Omni .

Before visiting, please consult our Using the Archives page on the library website for instructions on how to book an appointment and request material and reproductions. For additional questions, contact us at [email protected]. Statement on Language in Archival Records & Descriptions

Sustainable biodegradable coatings for food packaging: challenges and opportunities.

This review article provides a thorough overview of barrier coating materials that have been used in food packaging with a focus on biodegradable (bio-based or petroleum-based) materials, such as lipids, proteins, polysaccharides, agriculture waste and polyesters. The goal is to provide an opportunity to acknowledge progress made in this field, focusing on modifications made to coatings. These modifications aim to address the shortcomings of biodegradable substrates (either plastic or paper) and improve their performance, enabling them to compete with traditional petroleum-based food packaging materials. This includes their barrier against water vapor and oxygen, mechanical and surface characteristics (sealability and adhesion), as well as antimicrobial properties. The barrier of most biodegradable polymers underperforms in comparison with petroleum-based non-biodegradable polymers, which possess either high water vapor barrier or high oxygen barrier. Coating technology is a promising solution particularly in barrier improvement of biodegradable polymers. Currently, there are only metallized, or inorganic nanosheet coatings available for biodegradable films that meet food packaging requirements. There are some challenges in this field, for example, being able to retain the coating's biodegradability despite applied modifications to improve it's performance, the large-scale fabrication of biodegradable coatings, the coating's delamination and heat-sealability during service time, and the migration of the coating into the packaged food. Moreover, green chemistry and its sustainability needs in biodegradable polymeric coatings are also discussed regarding new ideas and possible directions for widespread application of coatings in food packaging. This is the first review that specifically summarizes biodegradable coatings on plastic and paper substrates with a focus on coating modifications to improve the performance of the base substrate to meet the required properties for food packaging applications.

• Avoid using "secondary" sources by finding and using the original source (e.g., Brown) whenever possible.
• If you can't find and use the original, list only your "secondary" source (e.g., Smith) in the reference list.

• If your quotation includes a citation, keep it in, but include only the source you are using (e.g., Lamont) in the reference list:

Reference List:

• If you need to cite a source within a source, you should only include a citation for the secondary source that you consulted in your reference list. For example, if you include a quotation from Aristotle that you found in a secondary work, you would provide a citation for this secondary work in your reference list.
