About PMC Canada

PMC Canada provides free access to a stable and permanent online digital archive of full-text, peer-reviewed health and life sciences research publications. It builds on PubMed Central (PMC), the U.S. National Institutes of Health (NIH) free digital archive of biomedical and life sciences journal literature and is a member of the broader PMC International (PMCI) network of e-repositories.

PMC Canada aims to provide a freely accessible, Canada-based archive of biomedical and health research findings. With PubMed Central, NLM has taken the lead in preserving and maintaining access to the electronic literature, just as it has done for decades with printed biomedical literature. PubMed Central aims to fill the role of a world class library in the digital age. It is not a journal publisher. NLM believes that giving all users free access to the material in PubMed Central is the best way to ensure the durability and utility of the archive as technology changes over time.

An international collaboration

PMCI is a collaborative effort between the U.S. National Library of Medicine (NLM), the publishers whose journal content makes up the PubMed Central archive, and organisations in other countries that share NLM's interest in archiving life sciences literature.

Partners

The PMC Canada partners are:

PMC Canada supports CIHR's Open Access Policy, which requires CIHR grant recipients to make their peer-reviewed publications freely accessible online within twelve months of publication. Our aim is to grow PubMed Central Canada into a premier public access resource of Canadian supported health research findings. To maximize the value of this Canadian-based public access archive, we wish to collaborate with other Canadian funders of health research who have committed to providing public access to their health research.

Overview

  1. What is PMC Canada?
    PubMed Central Canada (PMC Canada) is a repository of free, full-text, peer-reviewed articles in the fields of health and life sciences.

    PMC Canada, along with Europe PMC, is part of the PubMed Central International (PMCi) network. PMC Canada and Europe PMC are "mirror" sites of PMC (U.S.); that is, they receive and share content with PMC (U.S.). PMC Canada also accepts and processes author manuscripts funded by the Canadian Institutes of Health Research (CIHR). We hope to partner with other Canadian funding agencies in the future.

    PMC Canada is a collaborative effort between CIHR, Canada's National Science Library (National Research Council Canada's Canada Institute for Scientific and Technical Information (NRC-CISTI)), and the National Library of Medicine (NLM) in the U.S.

Audience

  1. Who is the audience for PMC Canada?
    PMC Canada visitors come from all over the world including Canada, the U.S., China, Japan, Taiwan, France and India. The site attracts approximately 8,000 unique visitors on a typical weekday.

Administration

  1. Who handles the day-to-day operations of the PMC Canada website and Manuscript Submission System?
    The PMC Canada website and Manuscript Submission System are handled by staff at Canada’s National Science Library, NRC-CISTI.

Access

  1. Do I need a subscription to access articles in PMC Canada?
    No. All of the articles in PMC Canada are available free of charge.

  2. Does PMC Canada provide barrier-free or open access?
    PMC Canada provides barrier-free access to its repository of health and life sciences research.

    PMC (U.S.) holds a PMC Open Access Subset, which is a relatively small part of the total collection of articles in PMC (U.S.). Since articles in PMC (U.S.) are also available in PMC Canada, these Open Access titles are available to you.

Content

  1. How many full-text articles are available through PMC Canada?
    As of May 2013, PMC Canada provides access to more than 2.6 million articles.

  2. What content types are included in PMC Canada?
    PMC Canada is a repository of peer-reviewed journal articles in the fields of health and life sciences.

  3. Does PMC Canada include research that has not been peer-reviewed?
    No. PMC Canada contains only peer-reviewed research articles.

  4. Does PMC Canada accept data and other types of "research outputs"?
    No. While CIHR's Open Access Policy applies to three categories of research outputs (peer-reviewed journal publications, research materials and research data), there are no plans to broaden the scope of PMC Canada to include anything other than peer-reviewed journal publications.

  5. Does PMC Canada include articles written in languages other than English? Yes. While almost all journal articles currently in PMC Canada are written in English, some are written in French. We hope to have many more French-language articles in the future.

    In order to provide broader coverage of non-English language material, PMC Canada must be able to ensure proper validation of the archival XML record in these languages. NLM is considering possible collaborations with national agencies in other countries, as well as other methods, to obtain the non-English language expertise needed to provide an adequate level of quality control for the PMC Canada archive.

  6. How current is the material in PMC Canada?
    The currency and age of material in PMC Canada varies by journal. Many journals which automatically make their content available in PMC Canada do so as soon as it is published. Others may delay release of content to PMC Canada from anywhere from a few months to more than a year post-publication. Most journals provide free access to full text in PMC Canada within a year of publication.

  7. How is Canadian content defined in PMC Canada?
    Canadian content is defined as manuscripts submitted by publishers or authors through the PMC Canada Manuscript Submission System.

  8. How is Canadian content "flagged"? All manuscripts received through the PMC Canada Manuscript Submission System are highlighted with the CIHR flag.

PMC Canada vs. PMC (U.S.), Europe PMC and PubMed

  1. What is the difference between PMC Canada, PMC (U.S.) and Europe PMC?
    The unique difference between PMC Canada, PMC (U.S.) and Europe PMC is the manuscript submission system for each site. At this time, only CIHR-funded research can be deposited into PMC Canada.

  2. What is the difference between PubMed and PMC (Canada, U.S. and /or Europe)?
    PMC Canada and PMC (U.S.) are full text repositories that contain citations and abstracts for the full text publications contained within each archive. Europe PMC is a full text repository which also contains PubMed citations and abstracts for publications whose full text is not available in Europe PMC.

    PubMed is a repository that contains citations and abstracts only for millions of peer-reviewed publications in the fields of health and life sciences. PubMed does not contain the full text of any publication, but a PubMed record may provide a link to the full text if it is freely available on the publisher’s website or in PMC (U.S.).

    All of the publications in PMC (U.S.), PMC Canada and Europe PMC have corresponding records in PubMed. However, PubMed contains citations for many more articles than are available in full-text form via PMC (U.S.), PMC Canada or Europe PMC. That is, not all of the citations in PubMed have corresponding full-text entries in PMC (U.S.), PMC Canada or Europe PMC.

    In summary, if you search PMC (U.S.) and PMC Canada, you will always be provided with access to the full-text. But if you search PMC (U.S.) or PMC Canada you will not be searching all of the content in PubMed. Alternately, if you do your searches in PubMed and the item is in PMC (U.S.), PMC Canada or Europe PMC, a link will be provided to access the full-text of the article at no cost.

  3. Is all material deposited in PMC Canada available in PMC (U.S.) and Europe PMC?
    Yes. Material deposited in PMC Canada goes first to PMC (U.S.). It is then made available or "mirrored" to PMC Canada and (copyright restrictions permitting) Europe PMC.

  4. If PMC Canada includes all that is in PMC (U.S.) and Europe PMC, why not just have one PMC?
    Although Europe PMC (U.S.), PMC and PMC Canada share content with one another, there are different policies governing the deposit of manuscripts into each repository. While PMC (U.S.) accepts only NIH-funded manuscripts, Europe PMC accepts research from several European funders and PMC Canada only accepts research funded by the Canadian Institutes of Health Research (CIHR).

  5. In order for it to be visible in Europe PMC and PMC (U.S.), do I need to submit my manuscript separately to PMC (U.S.) and Europe PMC in addition to PMC Canada?
    No. CIHR-funded author manuscripts will be mirrored to PMC (U.S.) and Europe PMC sites.

  6. Does PMC Canada provide the full-text of all articles in PubMed listed as having full-text available? No. When you click on a full-text link in PubMed, you leave PubMed and are directed to the full-text at an external provider's site. External providers range from PMC International sites (like PMC Canada) to publisher websites.

    If a PubMed citation does not show a link to the full-text of the article in PMC (U.S.), PMC Canada or Europe PMC, free or pay-per-view access to the full-text might be available via publisher websites, through online public or medical libraries, or electronic resources to which your organization subscribes.

    For more information on obtaining the full-text of an article whose citation appears in PubMed (when available), please consult the "How to Get the Journal Article" section of NCBI's "PubMed Help Guide."

Participating Journals

  1. What do the various levels of participation mean in the "Journal List"?
    The Participation Level in the PMC Canada Journal List indicates the type and level of participation in PMC.
    • 'Full' participation means the journal deposits all articles from each issue.
    • 'NIH Portfolio' journals deposit at least all NIH-funded articles, but may not include all of the journal's articles.
    • A 'No longer depositing' journal is not adding new material to PMC but the material that it deposited previously is still available.
    • 'Now Select only' titles were full participation or NIH Portfolio that have moved to a selective deposit model. (See the PMC Canada Special Collections tab.)

    The PMC Canada Journal List includes information about what content is available from each journal, as well as links to that content.

    More information on participation models can be found on NCBI’s Add a Journal to PMC page.

  2. Does PMC Canada contain the complete contents of all journals that are in its repository?
    No. Journals may deposit any of the following into PMC Canada:
    1. The complete contents of all issues, beginning with the first. For the older journals in this group, the back issues of a journal (generally, anything prior to the late 1990s) are available as digitized (scanned) copies of the original print journal.
    2. The complete contents of each issue for recent years, but not for all the early years of the journal.
    3. Non-complete issues (selected articles only; e.g., just those that are the result of CIHR-funded research, or those that the journal has published as open access articles.)

    In all three categories, PMC Canada contains the journal's final published version of the article.

    PMC Canada also contains author manuscripts of selected articles from several thousand other journals. These manuscripts are accessible via a PMC Canada search or a link from the corresponding PubMed abstract.

  3. Why don't we have access to the full-text of all articles in journals for which the participation level is "Full"?
    Although the PMC (U.S.) repository contains the full-text of all articles from fully-participating journals, access to them is gained only after the embargo period has passed.

  4. Is there a list of journals that are not available to PMC Canada?
    No. You can manually compare the availability of specific journal titles at each PMCi site by searching the list of participating journals for each site.
    PMCi site URL for journal list
    PMC Canada http://pubmedcentralcanada.ca/pmcc/journals/
    PMC (U.S.) http://www.ncbi.nlm.nih.gov/pmc/journals/
    Europe PMC http://europepmc.org/journalList

Future directions

  1. Will there be MeSH indexing to facilitate searching in PMC Canada?
    No. There are no plans to implement MeSH indexing in PMC Canada at this time.

  2. Will the SWORD protocol be implemented in PMC Canada?
    Perhaps. In 2008-2009, NRC-CISTI and CARL studied the feasibility of implementing SWORD for simultaneous deposit in PMC Canada and Canadian institutional repositories. While implementing SWORD proved technically feasible, it was not possible to implement it with the first release of PMC Canada as our software is part of the US National Library of Medicine’s very active code base. We will continue to keep abreast of developments with the protocol and will examine the viability of implementing SWORD.

    However, PMC Canada is OAI-PMH compliant, which allows institutional repository operators to easily harvest metadata and some full-text content for their repositories. For additional information about the PMC Canada OAI service, visit the Download section of this website.
