Highlights from the July - August 2002 issue of the NLM Technical Bulletin
Educational Clearinghouse Database: A Service of the National Training Center and Clearinghouse
Searching for educational materials or classes? Created by the National Training Center and Clearinghouse, the Educational Clearinghouse Database provides access to training materials from the National Library of Medicine, the National Network of Libraries of Medicine, and other organizations interested in health information. The database is searchable by content, format, audience and keywords, and can be browsed by content, format, audience, and title. The database is located at http://nnlm.gov/mar/online/; there is also a navigational link from the PSRML home page, http://nnlm.gov/psr/.
Update: Expanded ClinicalTrials.gov Search Capabilities
In May of this year, NLM added new features to the search interface for the ClinicalTrials.gov database of more than 6,500 clinical studies in approximately 69,000 locations worldwide. With this update in place, you can now:
- Search within results
- Use search operators like phrase searching, field limitation and Boolean operators
- View and modify searches after synonym expansion
- Get help translating natural language searches
- See links to associated PubMed citations
- Link to search requests
LinkOut to SERHOLD: a new feature in PubMed
PubMed's LinkOut program, originally developed to link to article full-text, has been expanded to link to information about a library's print holdings. Any library that has holdings data in SERHOLD may decide to participate in this program. To participate in LinkOut, send an email request to lib-reg@ncbi.nlm.nih.gov. Enter "LinkOut Registration Request" as the subject of the email. Include the following information in the body of the message: library name, contact person, email address, phone number, and address.
Links Pull-Down Menu on PubMed Citations
In order to accommodate the growing number of links between records in Entrez databases NLM has made a change to the display of retrieved citations in PubMed. The database links currently on citations have been consolidated into a pull-down menu. Rather than Nucleotide, Protein, Free in PMC, etc., that you used to see on some citations, you now see the word "Links" next to "Related Articles." Clicking on Links will open a menu listing the database links for that citation.
Two new links are being added to some PubMed records:
- "Cited in PMC" indicates the article is cited by at least one full text article in PubMed Central. The link takes you to the article(s) in PMC.
- "Cited in Books" indicates this article is cited in the bibliography of at least one online book in Bookshelf. Clicking this link will take you to the section(s) of the book(s) where it was cited.
From the Technical Notes:
- Find out just how many people use PubMed every month! NCBI has recently released a PubMed Searches graph that contains data on the number of searches performed monthly. The graph is available at http://www.ncbi.nlm.nih.gov/About/tools/restable_stat_pubmed.html and is accessible both from Overview on the PubMed sidebar and the Databases and Tools section of the About NCBI web page.
- A new search engine is now available from the NLM main Web site. FAQs on the service are available at http://www.nlm.nih.gov/searchfaq.html.
- The updated training manual, reflecting changes in PubMed, the NLM Gateway, and ClinicalTrials.gov since October 2001, is now available. The manual is used in the classes Introduction to Web-based Searching: Using PubMed, NLM Gateway and ClinicalTrials.gov and Keeping Up With NLM's PubMed, the NLM Gateway and ClinicalTrials.gov, and is available for download in both Portable Document Format (PDF) and Microsoft® (MS) Word formats.
