On Thursday, October 11, the National Library of Medicine released a new search engine for MedlinePlus, MedlinePlus en español and the NLM Library Web site. NLM has made this change to better meet the expectations and preferences of the millions of people who use NLM Web sites each month.
After extensive research, NLM selected search engine software from the Pittsburgh-based company Vivisimo. Vivisimo is also the current search solution for the www.usa.gov site (formerly FirstGov), which contains online information from the entire spectrum of U.S. government agencies.
The new search results feature enhanced relevance rankings and boldface search words in context, to help users select the best Web documents for their queries. An integrated spell checker suggests alternative search terms and spelling corrections.
To access the the new engine, look for the search box on most NLM pages.
Here's a results page. Notice:
1) The source at the bottom of each listing
2) Results organized by collection
In some cases, a search might also provide direct links to NLM Selected Resources

See Also: If some of this Vivisimio and medical info searching sounds vaguely familiar, kudos. For several years Vivisimo has offered ClusterMed.info (both free and fee-based) and BioMetaCluster that clusters results from PubMed, ClinicalTrials.gov, FDA Web, FDA: CDER, and several other sources.
See Also: A second UI for BioMetaCluster
Here you can dynamically cluster results from the TRIP Database, Harrison Direct, PubMed@NIH, and the MerckManual
See Also: One final note on searching PubMed with ClusterMed.info. Because of the metadata associated with each Pubmed citation, notice the various ways of dynamically clustering the results. The power of good metadata. You can cluster by words in the:
+ Title, Abstract, and Medical Subject Heading (MESH)
+ Title, Abstract only
+ MESH only
+ Authors name only
+ Affiliation only
+ Date of Publication only Here's an example search that shows these various clusters.

Recently I have found myself cooing over visualisation maps (and heat maps) of health and well being resources. The content rich data is overlayed with mapping technologies, and some interesting themes and patterns are emerging.
A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.
What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
Alacra Compliance saves time by aggregating information from both free and fee-based sources and enabling users to conduct an accurate federated search across these sources (coined “simultaneous search” by Alacra).
