Bosnian is a new language valid for MEDLINE indexing. Effective for 2004 publications forward, the three-letter abbreviation "bos" is to be applied during indexing of articles in the sole MEDLINE-indexed journal that is published in Bosnia and Hercegovina, Medicinski Arhiv (unless it is clear that another language is appropriate.)
To search PubMed for citations of articles published in Bosnian, use either the value bos[la] or bosnian[la].
For more on language codes with new display values, please see Technical Notes. NLM Tech Bull. 2003 Sep-Oct;(334):e1.
The following three languages and their three-letter abbreviations (language codes) have been added to PubMed. These languages are currently found only on OLDMEDLINE citations:
In order to remain consistent with Library of Congress usage, the following two language codes for languages already in use have changed as follows:

The January 2004 editions of the training workbooks are now available for downloading from the NLM Web site. Both workbooks were updated to reflect changes since October 2003.
The manuals are available for downloading in Portable Document Format (PDF) and Microsoft® (MS) Word formats. They are broken down into sections so you can choose the areas of interest to you. These materials correspond to the NLM's National Training Center and Clearinghouse training courses described at: http://nnlm.gov/mar/online/description.html.
Feel free to use any part of the workbooksyou may customize parts for training programs, demonstrations, or workshops you conduct. These workbooks are not copyrighted.
Training materials used in training on Toxicology and Environmental Health Web Resources, the Unified Medical Language System (UMLS), and Molecular Biology Information Resources are also available from this Web site.
The following journals are now participating in PubMed Central (PMC):
Content from volumes 1992 Jan;3(1) to 1997 Jan;8(1) of Molecular Biology of the Cell is now available in PubMed Central (PMC) as part of NLM's project to digitize the back issues of PMC participating journals. The coverage of Molecular Biology of the Cell in PMC had previously begun with 1998 Jan;9(1).

A new listserv, "books-announce," broadcasts announcements concerning updates to the NCBI Bookshelf. Subscribers to the listserv will learn when new books are added, when new editions of existing books are added, and information on other content updates.
You can subscribe to the books-announce mailing list at: http://www.ncbi.nlm.nih.gov/mailman/listinfo/books-announce
A new ClinicalTrials.gov feature allows users to view a map of study locations based on search results. Click on the "Map of locations" button on the Search Results page. Locations are displayed in three ways:
The number of available studies is displayed for each locations. In addition, four different colors are used to indicate the volume of studies in each location.
The National Center for Biotechnology Information (NCBI) has recently added a book to the Bookshelf:
Neuroscience. 2nd ed.
The books in Bookshelf may be searched directly from the Bookshelf site, via links from the Links pull-down menu from relevant PubMed® citations, or through the new Entrez Global query feature.
NLM has begun to perform gene indexing for three additional organisms: chicken, pig, and Xenopus tropicalis (Western clawed frog), raising the number of organisms in LocusLink to 13.
Initially there were five organisms in [This link has been retired; use instead http://www.ncbi.nlm.nih.gov/gene] LocusLinkhuman, mouse, rat, fruit fly, and zebrafish. HIV-1 was added on May 30, 2002. Cow (Bos taurus) was added on December 2, 2002, and Caenorhabditis elegans, a nematode, was added on December 31, 2002. In November 2003, Xenopus laevis (African clawed frog) and Strongylocentrotus purpuratus (sea urchin) were added to the list.

The eight additional entries in Tox Town, NLM®'s interactive guide to commonly encountered toxic substances, include common (or "criteria") air pollutants regulated by the Environmental Protection Agency:
Tox Town includes a one to two page description of each chemical as well as Internet links for more information. The Web site also shows where a chemical might be found in a town or city. In the Town or City Scenes, select "All Chemicals" at the bottom of the page to see the complete list of chemicals.
By clicking on the Dentist in Tox Town's City scene, dental health professionals can read about potential environmental health concerns at work, such as nitrous oxide exposure, infection control, and hazardous chemicals.
By clicking on the new Pharmacy in the City scene, you can see information about medicines, cosmetics, dietary supplements, drug and medical device safety, latex allergies, occupational health for healthcare providers, vitamin and mineral supplements, and more.
Clip art and publicity materials for Tox Town, suitable for Web sites or newsletters, are available at http://toxtown.nlm.nih.gov/clipart.html.
The contents of the 19511952 Current List of Medical Literature (CLML) were added to PubMed® in February 2004. OLDMEDLINE citations now total 1,704,728 citations, with the addition of these 186,889 citations from the 1951-1952 publications. Of these newly added citations, 89,557 are from the 1952 CLML and 97,332 are from the 1951 CLML.
OLDMEDLINE is a subset of PubMed available free of charge at http://pubmed.gov. For information about OLDMEDLINE, please see: http://www.nlm.nih.gov/databases/databases_oldmedline.html. You can read more on OLDMEDLINE citations in the following NLM Technical Bulletin article: Demsey A, Nahin AM, Von Braunsberg S. OLDMEDLINE Citations Join PubMed.

The PubMed Clinical Queries page has been revised:Rephrased Emphasis Labels
It is hoped that the new Emphasis label options will help clarify the type of search that will be conducted.
Filter strategies updated
For more information about their work, please see the following site: http://www.nlm.nih.gov/pubs/techbull/jf04/cq_info.html.
All PubMed subject subset strategies are reviewed at least once a year to check for possible revisions due to MeSH vocabulary changes, to add or delete terms, or to modify parts of the strategies. The following subset strategies were recently revised: Bioethics, Cancer, Complementary Medicine, Space Life Sciences, Systematic Reviews, Toxicology.
