Rebecca Williams gave the presentation on clinicaltrials.gov. Clinical Trials has over 165,000 registered clinical trials and observational studies with over 12,000 of those available on the website. This collection consists of both private and federal studies at all stages. Studies are registered at the beginning, updated when no new participants are being allowed in, when the study is complete, and when results are available. Each record is made of two sections. The first is the registration section which includes the protocol of the trial and recruitment information. The second section is the results section where the results are displayed on a table. Not all studies will include their results.
Where do these studies come from?
Researchers submit their information when they start their trials. It is important to point out that publishing results in this collection will not interfere with publication in journals as long as the results are published with the registration record. In fact, most medical journals require registration of all clinical trials, and some are mandated by federal law.
- Find potential trials for you or your patrons to participate in. It could be a place for you to refer patrons who are looking for different treatment alternatives.
- Track progress of trials.
- See what kind of trials are going on.
- Find investigators and centers that are doing research on a particular disease.

Modernizing History: The New (and much improved) IndexCat interface
This session was about the new IndexCat. Stephen Greenberg told us that there are 3.7 million citations XML downloadable. The new IndexCat is fast! It also has a new record display and format. The collection is made up of five series based mostly on the age of the material. Series 1-3 are complete while series 4&5 are still incomplete.
Stephen gave us an overview of how to search the new interface. The searching is full-text keyword, there is no controlled vocabulary. Some exciting upgrades to the IndexCat searching include Boolean functions, phrase searching, and truncation searching. One thing they are still working on are journal titles. Journal titles would change and often the journal editor would be cited rather than the journal title. This makes for an ugly situation but they are working on ways to make searching for journals in IndexCat easier.
Still Scanning After All These Years: New Digital Projects from HMD
Stephen gave the presentation on new digital projects from the NLM History of Medicine Department (HMD). He started his talk by admitting that the search engine of the Medical Heritage Library is not the best, but it is being upgraded. As for the scanning, that it’s good. They use a Kirtas scanner. These scanners are pretty cool and can turn book pages on its own (check out some videos online, they are fun to watch), plus they have a cold light source so they are safe for the materials. HMD turn the pages by hand since many of their books are fragile and they don’t want to risk damaging the books. The scanner produces a tiff file which is then uploaded as a PDF.
Many people assume that the fragility of the materials would be the major issue, but in reality the main concern is copyright. If the NLM has a document you need that isn’t online they will scan on demand for DOCLINE requests. These requests usually only take about a week. One thing to note is that the entire book will be scanned and sent to you as a PDF even if only a chapter or a few pages were requested.
Due to the complexity of journal metadata, journals haven’t been scanned. This is changing very soon! Some journal scanning will be starting by the first week of June. They are also doing incunabula.
NLM Resources Used In Disasters
Elizabeth Norton, Siobhan Champ-Blackwell, and Maria Collins presented on using the NLM in disaster situations.
The NLM Disaster Information Specialist Program provides “support for librarians providing disaster information outreach to their communities.” In the case of a disaster there are roles librarians can take. These include:
- Aggregate information
- Develop FAQs
- Develop helpful apps
- Act as call centers and charging stations
- Monitor social media
- Authenticate news and information
- Haiti 2010 earthquake
- Pakistan 2010
- Haiti 2010 cholera
- Japan 2011
- Philippians 2013
After all these occurrences the data was analyzed. It was seen that book literature was used more than journals. The most popular books were drug books and trauma books depending on the event. In the case of Japan radiation books were added. Data is analyzed after each event.
Marie Collins gave us the update on PubMed. Some stats include: 23.7 records, 5667 journals, and mobile searches have increased to 430,000.
One problem that was talked about is that of disambiguating authors. One solution to this is adding affiliation information for all authors rather than just the lead author. You may not notice this at first since it is a collapsed option. You can easily open them up to find the information. You can also change a setting in MyNCBI to make the default not be collapsed. Another solution to the author problem is the unique author identifier which comes from the publisher. There is a new field to search this identifier. Finally, there is a “computed author” search. If you click on an authors name in an abstract you will get articles written by that same author.
- The history function has been updated with the query now showing keywords rather than the search #.
- You can now also delete individual searches from the history.
- Recent activity is stored for six months and can be searched, sorted, and added to collections.
- Relevance sort!
- The algorithm is available in Help for anyone to see
- Cited by systematic reviews
- In the right hand of results of results display
- Links to resources that cite a study
- LinkOut to PubMed Health
- This “rescues zero results searches” by doing a modify search of all terms in all fields
- Results in two searches showing up on the search history
- Old Medline can be searched in two ways
- Oldmedline[sb] searches the subset of 400,000
- Jsubsetom searches entire two million
- New catalog filter for journals currently indexed in Medline
- PMCID-PMID-manuscript ID-DOI converter is available on the homepage
If you need any assistance the PubMed help desk is very helpful. Also keep your eye open for PubMed training classes.
Hilda Bastian gave this presentation on PubMed Health. PubMed Health provides help with finding systematic reviews and help with understanding them. The PubMed Health collection consists of systematic reviews, knowledge translation, and education materials. Systematic reviews have a few basics that qualify them as systematic reviews:
- Ask structured, pre-specified question
- Have systematic methods
- Methods aim to minimize bias
- May or may not have quantitative synthesis / meta-analysis
- There were no catastrophic problems!
- RDA is principle based rather than format based
- RDA makes a true representation of an item
- There was lots and lots of prep for implementation
- Daily upload from LC authority files updated
- Vocabulary changes were necessary for RDA
- Guidelines are available in the RDA Toolkit
