Apologies for crossposting (and length!)
Latest completed US National Library of Medicine Technical Bulletin below
(link to online is
http://www.nlm.nih.gov/pubs/techbull/mj02/mj02_issue_cover.html) Thanks to
my colleague Stephanie Brockhouse for this.
Other Medline related news from me:
1. I did a couple of searches recently which retrieved a lot of references
(particularly from UK nursing journals) which were published around a year
ago but have only just been entered on Medline (eg searching PubMed using an
Entrez Date (EDAT) limit of 60 days). I then checked the June 2002 Medline
additions (via DIALOG CD)- total was 45,379. Of which publication year:
2001 12,804
2000 1,680
1999 443
I contacted NLM to ask for more info, and got this reply:
'There are many instances where you will find articles' EDATs (Entrez
Dates) years apart from an article's actual publication date. Rather than
backlog, this is most likely due to the journal issue being received after
being claimed (this is often a long process). Also, from time to time NLM
is made aware of articles that were not originally picked up in MEDLINE, so
the disparity in the dates allows the article's inclusion in the database.
You may want to construct your search strategy to cover both the DP
(Publication Date) and EDAT fields to find new, added citations. If you are
not interested in citations that are years old, even if they are newly
added, then using the DP field is the better way to go.'
Personally, I still used the EDAT limit but also a publication date limit
(to get one of the updates down from over 1000 refs!)
2. re complementary and alternative medicine (CAM) :
* If you havent noticed already, the MeSH term is now 'Complementary
Therapies', replacing 'Alternative Medicine' (tho searching on both gets the
same results in PubMed).
* Jane D Saxton, Director of Library Services at a US university, has
loaded her useful guide to searching PubMed for CAM onto the web at

National Library of Medicine
Technical Bulletin 326 -May-June 2002
Linking MEDLINE citations to evidence-based medicine assessments and
summaries
Interest in evidence-based medicine has intensified in the medical
community. Some journals are now devoted to publishing analytical summaries
of articles published elsewhere, especially to analyse the reports in terms
of evidence-based medicine. Some MEDLINE journals that publish such
analytical summaries include ACP Journal Club, Evidence-Based Mental Health,
and Evidence-Based nursing.
To facilitate users' access to these analytical summaries, NLM has begun to
cite the summaries and to link them to the citations of the articles they
analyse, beginning with summaries published in 2002. These links will be
established when an appropriate item appears in any journal included in
MEDLINE.
The citation for the analytical summary will not include Medical Subject
Headings (MeSH) terms, but will be assigned the Publication Type COMMENT,
and 'Comment on/Comment in' links will be made between the citation for the
analytical summary and the citation to the original article is analyses.
Subject access will occur via the original article, and the MeSH terms
applied to it. The citations to the analytical summaries will not be
retrieved with the MEDLINE subset of PubMed because they will not have MeSH
terms.
List of Serials Indexed for Online Users 2002 available
The list of Serials Indexed for Online Users - 2002 can be downloaded in
Adobe PDF format (1.17MB) from
ftp://nlmpubs.nlm.nih.gov/online/journals/lsiweb.pdf If required the Adobe
Acrobat Reader can be downloaded free of charge from the Adobe website.
This list is designed to provide bibliographic information for serials from
which articles are indexed with the MeSH vocabulary and cited in MEDLINE.
Citations from these serials date back as far as 1966 and include data from
all serials indexed for the formerly separate NLM databases AIDSLINE and
HealthSTAR and data from core serials indexed cover-to-cover for the
formerly separate BIOETHICSLINE, HISTLINE and SPACELINE databases.
New version of Gateway released including the addition of citations from
1957 to OLDMEDLINE
* Among the improvements to Gateway has been the opportunity to enter
month and day for publication date searching.
* A "Display Results" button added to the Details of Search page
* An Email verification has been added so users will receive an
advisory message if sending email fails.
* Users will be able to hit the "Enter" key instead of "Search" button
to initiate a search.
* OLDMEDLINE search results can now be retrieved from XML data. This
allows the display of diacritics.
The OLDMEDLINE collection has been extended and now includes journal
citations from 1957 to 1965. In addition a new collection "MEDLINEplus
Medical Encyclopedia" has been added in the Consumer Health category.
New look for TOXNET and DIRLINE plus a new database called Haz-Map
The National Library of Medicine has launched a new look for its TOXNET and
DIRLINE search interfaces.
The new features can be found at http://toxnet.nlm.nih.gov and
http://dirline.nlm.nih.gov
Briefly these are
* Streamlined search interface
* Search all TOXNET databases simultaneously
* Modify search from the results page
* New limits page for HSDB customized searches
* New format and expansion for DART (DART Core and DART Special)
Additionally the new Haz-Map database has been released. This is an
occupational health and toxicology database designed to link jobs and
hazardous job tasks to exposure to chemicals, and occupational diseases and
their symptoms. It is possible to link Haz-Map from
http://sis.nlm.nih.gov/Tox/ToxMain.html or go directly at
http://hazmap.nlm.nih.gov
Instructions on how to use these new search interfaces will soon be
available.
About NCBI
A new user friendly About NCBI section of the National Center for
Biotechnology Information website has been released.. For more information

PubMed's Journal Browser provides links to Locatorplus
PubMed's Journal Browser provides a way to look for journals included in
PubMed. Until recently NLM could not provide links from the journal names
retrieved by the Browser to the catalogue Locatorplus, so a link to another
source of information, PubList, was provided.
Changes to Locatorplus now allow PubMed's Journal Browser to provide a link
to the detailed information about a journal in NLM's catalogue. Use this to
find information such as the dates of publication, the frequency of
publication, and the name and address of the publisher.
The display of retrieved journals in the Journal Browser includes:-
* The full titles - links to bibliographic records in Locatorplus
* The ISSN(s) (some may not have one)
* The title abbreviations for the journals - links to a PubMed search
for that journal
New MeSH feature on Locatorplus
NLM has added a new search type, PubMed Title Abbreviation, to Locatorplus
allowing users to search for a PubMed journal title abbreviation in the
Library's catalogue. To perform this search, enter a PubMed abbreviation in
the "Search for" box, click on "PubMed Title Abbreviation" from the "Search
In" menu, and then click on "Search". This new feature performs a "left
anchored" search of the MARC bibliographic 210 field, therefore, the
retrieval will include a list of PubMed titles that begin with the
abbreviation you searched.
Additional Bioethics citations added to MEDLINE/PubMed: Court decisions and
laws
Approximately 700 additional Bioethics related journal citations unique to
the former BIOETHICSLINE database are now in MEDLINE and can be searched in
PubMed. These are primarily citations to court decisions and laws that were
not added to MEDLINE with the majority of Bioethics related journal
citations last year. The remaining 200 citations will be added shortly.
