PMC released a new and improved journal list on March 31, 2009, after a comprehensive redesign for greater clarity and organization.

The new design not only combines the full-list and tabbed-list views of the previous version but also includes some new or updated features to provide users with a greater overview of the total PMC archive. Looking at this new list, you will find:

1. An Expanded View of PMC journals that includes NIH Portfolio
2. Special Collections
3. A New “Participation Level” Journal Category
4. Hide/Show Display Option for Predecessor Titles
5. Article and Journal Search Feature

For more information, see the complete article in the May-June issue of the NLM Technical Bulletin: https://www.nlm.nih.gov/pubs/techbull/mj09/mj09_pmc_redesign.html

You can now find embargoed articles and their corresponding PMCIDs through a recently released search option in the PMC Entrez database. Using the “Limits” tab, click in the field, “Show both free and embargoed articles” and refine your search by journal, author, date, article type, and/or tag term, as needed. Once you’re on the summary page, click on the “embargoed” tab at the top to find the articles in this category. You can then find the PMCID and date of availability at the bottom of the article citation, as indicated in the example below. Note: The PMC search option only includes articles with an initial embargo of up to 12 months. Articles with an embargo greater than 12 months are not compliant with the NIH Public Access Policy and will appear in search results only when the full text is free in PMC. For more information, see the article in the September-October issue of the NLM Technical Bulletin.

A new page, Public Access & PMC, has now been added to the About PMC section of the PubMed Central site. “Public Access & PMC” provides information on the relationship between PMC and the NIH Public Access policy, including the difference between the NIH Public Access journal list and PMC journal list. In particular, authors and publishers should find this new site to be a useful resource.

PMC recently redesigned its URL format to allow for easier usability as well as consistency across the NCBI site. To implement this change, we moved the previous site, www.pubmedcentral.nih.gov, into the NCBI domain as a sub-site. You can now access the PMC home page at https://www.ncbi.nlm.nih.gov/pmc.

The primary advantage of the new format is to enable the PMC site to become more fully integrated with other NCBI resources. The new URLs are also more user-friendly—they no longer include technology-driven terminology, such as CGI script names and file extensions (Figure 1).

Figure 1—Old URL for Journal Page with CGI Script Name

Instead, note that after the NCBI/PMC address, the URL first identifies the type of resource, e.g., the PMC journal list, with subsequent identification for a particular subset of that resource—in this case, the journal number (Figure 2).

Figure 2—New URL for Journal Page with Journal Number

Additionally, you will have greater flexibility in accessing particular types of material because, in a number of cases, more than one URL can be used for the same resource. In these instances, one URL is considered to be canonical, or primary; however, using any of the ancillary URLs for that resource will redirect you back to the canonical one. For example (see Figure 3), although the first URL, which represents the PMCID, is considered to be the canonical URL, you may also access the article by using other identifiers, such as the pmid, doi, or the issn-volume-issue-page (ivip).

Figure 3—Canonical and Ancillary URLs for the Same Full-Text Article

Finally, with the roll-out of these more stable and standardized URLs, as in the table below (Figure 4), you will also find it easier to modify the web addresses in your browser. Note that the canonical URL is given first and is in bold; the ancillary URLs are listed below it.

Figure 4—Table Display of all New URLs

Although the new URLs are firmly in place, please also note that we haven't completely discarded the old to bring in the new. If you do use an old URL, it's not a problem. Your browser will be redirected to the new location.

Four new members have been appointed to serve on the PMC National Advisory Committee: Mike Rossner of Rockefeller University Press, Jan Fassler of the University of Iowa, Ivy Anderson of the California Digital Library, and Delores Meglio from the Knovel Corporation. Each member will serve a 4-year term. The next meeting of the committee is scheduled for June 4, 2010. For more information on the committee, see PMC National Advisory Committee.

The Public Access & PMC page has been redesigned for greater clarity and usability. In addition to including a list of the FAQs at the top, the new page features a table illustrating all the ways to find various reference numbers for an article: the PMID, NIHMSID, and most important, the PMCID, which must be used to demonstrate compliance in terms of the NIH Public Access Policy.

Four new members have been appointed to serve on the PMC National Advisory Committee: Philip Bourne, of the University of California, San Diego; Sophia Colamarino, an independent consultant in San Francisco; Paul Courant, of the University of Michigan; and Patricia Thibodeau, of Duke University. Each member will serve a 4-year term. The next meeting of the committee is scheduled for Friday, June 17, 2011. For more information on the committee, see PMC National Advisory Committee.

PMC has gotten a facelift-- or more accurately, an interface-lift! The home page, search page and other PMC informational pages have all undergone an overhaul, in order to provide users with easier navigation, enhanced features, and a look and feel that is more consistent with other recently updated NCBI sites, such as PubMed and Bookshelf. Additional new features and updates will be coming soon. For more information on navigating the new site, see the article in the July-August issue of the NLM Technical Bulletin.

The following new members have been appointed to serve on the PMC National Advisory Committee: Martha Bedard, Dean of Libraries at the University of New Mexico; and Lorraine Haricombe, Dean of Libraries at the University of Kansas and a member of SPARC's board. The next meeting of the committee is scheduled for June 19, 2012. For more information, see PMC National Advisory Committee.

The PMC user's guide, PMC Help has been updated to include new and improved information on navigating the site as well as descriptions and instructions on using the new search functions, such as Limits and Advanced Search Builder. Further updates will also be forthcoming.

NCBI has developed a new web presentation style called PubReader, which offers you an easier way to use your Web browser to read the articles in PMC. Designed particularly for enhancing readability and navigation on tablet and other small screen devices, PubReader can also be used on desktops and laptops and from multiple web browsers. For more information on PubReader, see the article in the November-December issue of the NLM Technical Bulletin.

As of February 1, 2013, the following new members have been appointed to serve on the PMC National Advisory Committee: Ms. Sharon Terry of the Genetic Alliance; Dr. C. Victor Jongneel of the University of Illinois at Urbana-Champaign; Dr. Bevin Engelward of the Massachusetts Institute of Technology; Dr. Randall Morse of the Wadsworth Center; and Dr. Adelita Cantu of the University of Texas. For more information, see PMC National Advisory Committee.

PMC is pleased to announce the new OA web service, designed to allow tool developers an easier way to find content in the PMC open access subset. Until now, it has not been easy for outside users to determine which articles in the subset are new or have been updated recently. Our new OA web service addresses this need. It provides a simple API to allow you to query the subset, to find PDF or tgz (tarred-gzipped) format files, either by article ID, or by date/time ranges. More information, along with examples, is available from the documentation page, at OA Web Service. Your feedback is welcome; please send it to the PMC Help Desk, at pubmedcentral@ncbi.nlm.nih.gov.

PMC has recently replaced the PMC-News mailing list and its accompanying RSS feed with a new PMC-Announce list and a new RSS feed. Please note that the older list and feed have now been retired. To subscribe to the new announcement list, see https://www.ncbi.nlm.nih.gov/mailman/listinfo/pmc-announce/. To see the new RSS feed, update your news reader to subscribe to https://www.ncbi.nlm.nih.gov/pmc/about/new-in-pmc/?format=rss.

PMC has recently released an updated version of its PubReader view. The new version (1.2) includes a "search this page" feature that allows you to find specific terms within the article. The latest source code is also available from the GitHub repository.

PMC has just released an upgrade to our ID converter, now dubbed the PMCID - PMID -Manuscript ID - DOI Converter. This utility allows you to start with the unique identifier for an article that is in PMC, and find additional unique identifiers that may apply to the article. Improvements include support for DOIs, auto-detection of the ID type based on its format, and enhanced output. It also provides output in any of several different formats: HTML, XML, JSON, or CSV. This tool uses an underlying web service, that is also publicly available for those needing programmatic access to this data. See the ID Converter API documentation.

As of August 2016, PMC is home to four million articles! To make this wealth of full-text content easier to navigate, PMC has rolled out a few updates:

1) Search Result Filters
On all search results pages, you will now see filters (similar to PubMed’s filters) on the left-hand side that allow you to filter your results by article attributes, publication date, research funder, and search fields. These filters replace the Limits page and allow you to more readily:

• find open access articles (PMC has more than 1.35 million open access articles that can be reused according to their license statements),
• explore PMC’s rich historical content from NLM's back issue digitization project,
• browse research supported by PMC-participating funding organizations (click "Customize" to view additional funder options),
• and much more.

You can now also quickly add articles that are under a 12-month or less embargo in PMC to your search results by selecting the “Include embargoed articles” filter option under Text Availability. See the PMC User Guide for more information on these filters.

2) Reference List Display
Using related article data available in PMC, articles that cite papers that have been either retracted or named in a Findings of Research Misconduct issued by the HHS Office of Research Integrity and not yet retracted will now include a red hyperlink to the relevant notice directly from the article’s reference list. This update will help users more easily identify post-publication updates to existing research.

A large-scale update of the file names used for articles available via the PMC FTP service for bulk download was undertaken in early January 2017. The new file naming convention is PMCID-based (e.g., PMC4855680.tar.gz) rather than being built from article citation data (i.e., journal abbreviation_pub date_volume_issue_page). This update was made following user reports that the previous naming convention was resulting in missing contents in cases where citation data was duplicated across multiple articles. The new convention will ensure that file names are unique and that the corpus available via the FTP service is complete.
