PubMed and security warnings

Today PubMed along with all NCBI sites permanently changed their web addresses to use the HTTPS protocol. Unfortunately, this is now prompting a security warning when using the Library’s off-campus link to PubMed. Although in this case there is no real danger in proceeding, you will need to add a security exception to your browser in order to get to PubMed.

For Chrome, first click “Advanced”


Then click the link that begins with “Proceed to…” in order to add the exception to Chrome:


In Internet Explorer, click the link “Continue to this website (not recommended)”:


In Firefox, first click the “Add Exception” button:


Then click “Confirm Security Exception” to add it to Firefox:


Finally, for those for whom Safari is your browser of choice, you just need to click the “Continue” button in the window that pops up:

Happy birthday, PubMed!

birthday cake

The database everyone loves (and hates at times), PubMed, is turning 20!

“PubMed was first released two decades ago in January 1996 as an experimental database under the National Center for Biotechnology Information (NCBI) retrieval system. The word “experimental” was dropped from the Web site in April 1997, and on June 26, 1997, a Capitol Hill Press conference officially announced free MEDLINE access via PubMed.”

Pubmed 1996

It’s gone through several redesigns and refinements since 1997.  The staff at NLM and NCBI are constantly improving access, coverage, and ease of use for PubMed and have come up with several features that help searchers.  This article discusses several of these improvements.  Prior to 1997, access to MEDLINE was only available through paid services, such as GRATEFUL MED, DIALOG or in CD ROM format.  Many times users were charged by the minute, by the search, or by the citation to download.  Users had to have their search strategy planned out exactly, login, type it as quickly as possible and then log off while watching the charges add up.  Things have changed!

PubMed 2016

Happy birthday, PubMed!  You have made health sciences research so much easier in the past 20 years!

PubMed changes

Recently, PubMed has announced that it has changed a few popular features that you may notice in your search results:

Within the article summary display, two changes have been made.  The term “Related Citations” has been changed to “Similar Articles”.  It was thought that “Related Citations” was ambiguous.,  The algorithm to generate the results of a search on for similar articles has not changed, just the name of the feature.  Also, the status tag line has been removed from the article summary display.  Most users will not notice this change but experienced searchers may.  The status tag line is still included in the Abstract display.


The “Save Search” link for creating My NCBI email alerts has been renamed “Create alert” and the “RSS” link has been renamed “Create RSS”.  Once again, these changes will not affect the functionality of PubMed they are only intended to eliminate ambiguity and to make the process smoother.


Finally, for those who use PubMed Mobile, there have been updates with a number of styling modifications and additional enhancements including a “Trending articles” feature.

For more information about these changes, you can refer to the New and Noteworthy link on the bottom of the PubMed screen or refer to the NLM Technical Bulletin.

PubMed Commons

Attention researchers published in PubMed:

PubMed Commons?áis an exciting new pilot project from the National Library of Medicine that allows researchers to comment on any scientific publication indexed in PubMed and to read the comments of others.

“PubMed Commons is a forum for open and constructive criticism and discussion of scientific issues. It will thrive with high quality interchange from the scientific community.”

Currently, PubMed Commons is in a pilot testing phase and only invited participants can add and view comments in PubMed. However, anyone in the pilot phase can invite a fellow author indexed in PubMed. All they need is your PubMed ID (PMID) and e-mail address. For more information on how to join PubMed Commons click here and stay tuned for the next phase of this project!

Testing, Testing: PubMed Commons Community Forum

PubMed Commons, a new forum community created for online collaboration for ÔÇ£constructive criticism and discussion of scientific issues,ÔÇØ has introduced a pilot version.

During its closed pilot phase, PubMed Commons will be allowing accounts using approved email addresses from PubMed authors to participate. ?áNIH or Wellcome Trust grant recipients can also join and invite others to join. You can test whether you have access here Users will also need a My NCBI account.

This Month in History: Dr. Hamlett & Zoological Treasure Hunting

Ever wondered how to catch a lizard? You might think to consult wikiHow or you might look up an instructional video on YouTube. Consulting our Digital Collection of newspaper clippings, however, would reveal quite an interesting portrait of a rugged, LSU Indiana Jones in pursuit of a rare treasure: the live-birthing lizard.

In 1953, the Times-Picayune ran an article on one Dr. George W. D. Hamlett, faculty of the LSU Medical School Department of Anatomy, whose research practices involved catching his subjects in the American Southwest rather than in a lab. Nets are all well and good for the casual lizard hunter, but Dr. HamlettÔÇÖs methods included an elaborate system of hammer, chisel, stick noose, and rifle. In order to capture the illusive live-birthing female lizard, he donned the traditional gear: khakis, hiking boots, and traded a fedora for a sun hat; armoring himself thus, he chiseled lizards out of rock formations and sought the mammal-like desert lizard among the trees. His interest in these lizards lay in their ability to produce young not through external development in an egg, but within the female of the species, an oddity for the reptile. Though Dr. Hamlett lacked the Indiana Jones bullwhip and the characteristic fear of snakes, his adventures were nevertheless harrowing.

The character of Dr. Jones is perhaps based on Sir Arthur Conan DoyleÔÇÖs character, Professor Challenger (a figure in turn based on his own Professor Sir William Rutherford) who is famous for having combined several areas of study such as archaeology, anthropology, and zoology in the pursuit of a totalizing knowledgeÔÇöÔÇ£Science seeks knowledge. Let knowledge lead us where it will, we still must seek it. To know once for all what we are, why we are, where we are, is that not in itself the greatest of all human aspirations?ÔÇ£(When the World Screamed). In the same way, Dr. HamlettÔÇÖs study of embryology continued on many divergent paths as he explored the complexities of the long-tongued bat, the badger, the armadillo, the cat, the coyote, and the American monkey, finally culminating in his study of humans.?á Some of his published works, ÔÇ£Embryology of the Molossoid Bat,ÔÇØ ÔÇ£Some Notes on Embryological Technique,ÔÇØ and ÔÇ£Human Twinning in the United StatesÔÇØ can be accessed through PubMed.

Though the similarities between Dr. Hamlett and Dr. Jones may not be many, there is an air of adventure to every quest for knowledge. Why can the scientist not leap across cliff faces and come to the rescue every now and then? But please be aware that there are no catacombs beneath this libraryÔÇÖs floorÔÇöyouÔÇÖll have to go to Venice for that.


Glimpse of the Past is an ongoing project to promote the Louisiana Digital Library effort. This Month in History will present for your reading pleasure a closer look into a newspaper clipping of note from our Digital Collections and articles relating to the LSU Medical School.

Friday fun: Pimp my Pubmed

An article from Bite Size Bio delves into some techniques for monitoring PubMed using Google Reader. PubMed has offered the ability to create RSS feeds from searches since 2005, which is highly useful in customizing your online consumption of journal literature.

Here, I will describe the way IÔÇÖm combining RSS feeds for PubMed search results with Google Reader and a GreaseMonkey add-on to obtain a nicely readable list of articles pertinent to my own interests
The article is written by a third year PhD student from Montpellier, France.

PubMed Limits are now Filters

Where you go to set PubMed?álimits such as dates, language and article types has changed – hopefully for the better. It’s all just semantics with a little bit of functional design thrown in, really.

Limits ?áin Pubmed are now called Filters. They are located on the left hand side of the PubMed screen. This video from NCBI shows where to find filters and how to use them. (Previously they were located under the search box on a separate page called Limits.)

Confused? Enraged? Apathetic? We welcome your responses and questions – just give us a call, email or chat and we’ll do our best to help.

Phrase searching in PubMed

Problem: you want to search PubMed for a phrase like text messaging, but the phrase keeps getting broken up.

Solution: when searching for phrases:

ÔÇó Search the phrase first without quotes or search tags.
ÔÇó Check Search details to see how the search was translated.
ÔÇó Use quotes (” “) when your phrase is broken apart.

For details and screen shots, read the complete article at

Using quotes work really well when you are looking for a specific article title!

MeSH turns 50

MeSH is the controlled vocabulary used by the National Library of Medicine to organize information in the health sciences; it is the underpinning of MEDLINE.

While first discussed at a symposium in 1947, the first volume of the printed subject headings was published in 1960. The last printed volume was issued in 2007, but the database (which is both alphabetical and hiearchical) continues to be available in electronic form as the MeSh browser.

NLM will offer a videocast on Thursday, November 18th from 1-2:30 (CST) by Robert Braude, PhD, entitled MeSH at 50 ÔÇô 50th Anniversary of Medical Subject Headings.

PubMed SLOW…

PubMed will be operational but may be intermittently slow starting today Friday, November 13 at 2:00 PM until Saturday, November 14 at 7:00 PM. Sorry for the inconvenience.
