<p>
A new version of the <a href="http://gateway.nlm.nih.gov">NLM Gateway</a> has been released with some notable changes.
</p>
<ul>
<li>A new collection, "AIDS Meetings", has been added to
the NLM Gateway in the Meeting
Abstracts category. The AIDS Meetings collection
has the meeting abstracts from the XIII International
AIDS Conference held in Durban, South Africa, July 9-14, 2000.
These are not MeSH indexed. Please note that the document collection formerly referred to as "AIDS Meetings" has been renamed "AIDS Meetings (with MeSH)."</li>
<li>A change has been made in searching by field qualifiers. In the
new release, all field qualifiers should be entered after the search
term or terms, and must be entered after each term, for example: "macular degeneration" [mh]. This is consistent with
the method used in PubMed. Previously,
field qualifiers were entered before the search term or terms, and the
field qualifier applied to the search terms that followed it until a
new field qualifier was entered. </li>
<li>The Login page and the Create New User ID page for the Locker and Preferences features have been redesigned.</li>
<li>On the Limits screen, the default ending publication year (if not specified by the user)
is the current year. Previously the default ending publication
year was the beginning publication year.</li>
</ul>
<p>
In addition, some software bugs were fixed, and changes
to the underlying system were made to improve Gateway functionality
and efficiency. Comments and questions are always welcome, and
may be sent to <a href="mailto:gateway@nlm.nih.gov">gateway@nlm.nih.gov</a>.

<h3><a name = "browser"></a>2001 MeSH Browser Available</h3>
<font size="2"><strong>December 21, 2000</strong> [posted]</font>
<p>
The 2001 <a href="http://www.nlm.nih.gov/mesh/MBrowser.html">MeSH Browser</a> is now available from the <a href="http://www.nlm.nih.gov/mesh/meshhome.html">MeSH Home Page</a>. The new browser encompasses useful features from the <em>Annotated MeSH</em> and the <em>Tree Structures</em>. It is designed to help quickly locate descriptors of possible interest and to show the hierarchy (trees) in which descriptors appear.

<h3><a name = "xml"></a>NLM Leases MEDLINE and other Databases in XML Format at No Charge in 2001</h3>
<font size="2"><strong>December 21, 2000</strong> [posted]</font>
<p>
MEDLINE will now be distributed to licensees in <a href="/news/medlinedata.html">XML format</a> using a Document Type Definition (DTD) to define the XML structure. (Please remember that MEDLINE is expanding its coverage in the area of life sciences and that unique journal citations from the former HealthSTAR, AIDSLINE, HISTLINE, SPACELINE, BIOETHICSLINE, and POPLINE databases will be phased into MEDLINE.) DTD's will be defined during 2001 for other NLM databases that will eventually be distributed in XML format such as MeSH and various TOXNET files.
</p>
<p>
There are no fees charged to lease NLM databases in 2001. See <a href="http://www.nlm.nih.gov/databases/leased.html">http://www.nlm.nih.gov/databases/leased.html</a> for additional information about leasing NLM databases. Use of the legacy ELHILL Unit Record Format for data distribution has been phased out as part of NLM's widespread reinvention activities.

<h3><a name = "health"></a>Finding and Using Health Statistics: A Self-Study Course</h3>
<font size="2"><strong>December 21, 2000</strong> [posted]</font>
<p>
The National Information Center on Health Services Research and Health Care Technology (NICHSR) of the National Library of Medicine has added this distance learning program to its Web site at <a href="http://www.nlm.nih.gov/nichsr/outreach.html">http://www.nlm.nih.gov/nichsr/outreach.html</a>.
</p>
<p>
The course was developed by Dan Melnick, Ph.D., through a contract from NICHSR and was originally presented by Dr. Melnick at the 2000 Annual Meeting of the Medical Library Association. It is based on Dr. Melnick's latest book, <em>Portrait of Health in the United States</em> (January 2001, Bernan Press).
</p>
<p>
Health statistics can be elusive and difficult to interpret. This course provides librarians, health services researchers, and public health professionals with some basic concepts for understanding health statistics, as well as pointing to some invaluable Internet portals.
</p>
<p>
We are looking for constructive feedback! Please send your comments on this program and/or suggestions for future related courses to <a href="mailto:nichsr@nlm.nih.gov">nichsr@nlm.nih.gov</a>.

<h3><a name = "genome"></a>Public Working Draft Version of Human Sequence Available</h3>
<font size="2"><strong>December 21, 2000</strong> [posted]</font>
<p>
In a letter published in the September 1, 2000 issue of <em>Science</em> and in a news brief published in the August 31, 2000 issue of <em>Nature</em>, the International Human Genome Sequencing Consortium described a number of electronic sites where the public working draft version of the human genome sequence can be found in its most useable forms.
</p>
<p>
The links below are to three different (but complementary), assembled views of the human genome,
together with useful browsing tools that provide a wide variety of
annotations of the sequence. These sites are updated frequently.

<h3><a name = "indexing"></a>Change in Selectively Indexed Journal Policy: Reminder</h3>
<font size="2"><strong>December 22, 2000</strong> [posted]</font>
<p>
As announced in the article, <a href="/pubs/techbull/nd99/nd99_changes.html">MEDLINE&#174; Data Changes Expected</a>, in the November-December 1999 issue of the <em>NLM Technical Bulletin</em> and again at the <a href="http://www.nlm.nih.gov/pubs/techbull/mj00/mj00_mla_online.html">May 2000 Annual MLA Convention</a> in Vancouver, B.C., Canada, NLM has eliminated "selective indexing" for all but a handful of general science and chemistry journals. All other formerly "selectively-indexed" journals, numbering about 250, are now indexed cover-to-cover. Citations are being created for all articles in journals that continue to be selectively indexed. These citations will appear in PubMed and be retrieved by author or text word searching; they just won't have MeSH indexing or other data such as Publicaiton Types that are added as part of the indexing process.
