Apologies for crossposting
I attach my colleague's summary of the latest completed US National Library
of Medicine's Technical Bulletin
(http://www.nlm.nih.gov/pubs/techbull/jf02/jf02_issue_cover.html).
Personally, I have been particularly interested in the new systematic review
filter in PubMed's Clinical Queries (on the left blue sidebar),although of
course its broader than the stricter interpretation some of us might use.
Please note that the PubMed tutorial and training manual havent been updated
with recent changes like this. The cluster of help/faq/new options at the
top of PubMed's left sidebar continue to be the most current sources of
information.
The Library Association has started running some courses on Medline with
Tony McCulloch from BL as the trainer- contact them direct for details.

> Comments/Corrections are Links in PubMed
>
> The Comments/Corrections family of fields was created last year. The data
> in these fields (listed below) are citations to other associated journal
> publications, e.g., comments or errata. In most cases, these data now
> display as links that take you directly to the other record in PubMed,
> making it easy to move between associated citations. For example, you can
> link from a citation for a letter that comments on another article to the
> PubMed record for that article. On the record for the article, you can
> link to the letter. If the citation is not a link, it means the link has
> not been established yet, or there is no record for that citation in
> PubMed.

> Herbs: Clarification of Medical Subject Headings - Annotated Alphabetic
> List 2002
>
> Subsequent to the printing of Annotated Alphabetic MeSH plans for citation
> maintenance were changed. Because of the dual meaning of Herbs problems
> arose as to whether is should be treated botanically or idiomatically.
>
> Because of the difference in meanings, different choices were made for the
> maintenance of records containing the MeSH Heading "Herbs" in MEDLINE and
> in Locatorplus. "Herbs" in MEDLINE was changed to "Angiosperms." In both
> MEDLINE and Locatorplus, all citations with a heading from the
> Angiosperrms [B06.388.100] tree which had the subheading "therapeutic use"
> had the new MeSH heading "Phytotherapy" applied to them. In Locatorplus,
> the use of "Herbs" had been predominantly for the medicinal uses, and the
> Heading "Plants, Medicinal" was applied instead of "Angiosperms" with one
> exception: the Heading "Herbs" with the qualifier of "history" was
> replaced by "Phytotherapy" qualified by "history".
>
> You may wish to make a notation in the Medical Subject Headings Annotated
> Alphabetic List 2002 (see page I-87) to correspond to this post-printing
> revision.
>
> Angiosperms (in MEDLINE)
> Plants, Medicinal (in Locatorplus with the 2 exceptions noted above)
>
>
> More frequent release of MEDLINE records to PubMed and licensees
>
> NLM has announced that completed MEDLINE citations (fully MeSH-indexed and
> quality controlled) are now released from their data creation system on a
> schedule that permits PubMed users to see newly completed records five
> times a week (Tuesday-Saturday). Many of these completed records are
> replacing the in process records already in PubMed. This change enables
> them to make fully indexed MEDLINE records available sooner. Records from
> the first "daily" update appeared in PubMed on January 9, 2002. These same
> records are released to MEDLINE licensees Tuesday-Saturday.

> Cochrane Database of Systematic Reviews included in MEDLINE
>
> NLM has been indexing the Cochrane Database of Systematic Reviews for
> MEDLINE since Summer 2000. The reviews are full text articles reviewing
> the effects of healthcare that are both highly structured and systematic,
> with evidence included or excluded on the basis of explicit quality
> criteria to minimise bias. Data are often combined statistically (with
> meta-analysis) to increase the power of the findings of numerous studies,
> each too small to produce reliable results individually.
>
> As with all MEDLINE citations, the Cochrane Reviews citations include
> bibliographic information and abstracts only, not the full text of the
> article. There are two ways to get the full text of a Cochrane Review
> article:-
>
> 1) Loansome Doc - order full text copies of review articles from a
> medical library. Contact your regional medical library for more
> information. Be advised that because of Cochrane's licensing policies
> your participating library may not be able to fulfil your request so it is
> a good idea for your request to also include NLM. NLM fulfils all
> requests for Cochrane material by mail regardless of the delivery method
> that you request.
>
> 2) The Cochrane Library order full text articles directly from the
> Cochrane Library website.
> Choose Document Delivery from the menu for more information.

> New PUBMED filter: Systematic Reviews
>
> A common complaint among those looking for biomedical information is that
> there is too much of it - too many journals, too many articles, and too
> little time. Possibly as a result of this, systematic reviews are
> becoming more popular.
>
> In November 2001 a Systematic Reviews search filter was added to PubMed on
> the Clinical Queries screen to make it easier to retrieve citations for
> these distinctive articles.
>
> Strategy used for the filter
>
> The filter works by combining the users search term(s) with citations that
> were retrieved by PubMed's Systematic Reviews search strategy.
>
> The strategy has three parts:-
>
> The basic strategy
>
> There is no Publication Type in MeSH for "systematic reviews" therefore
> the basic strategy searches for a variation of the term in the title and
> abstract. It also includes Publication Types and free-text searches for
> Meta-Analysis, Guidelines and Consensus Development Conference. The term
> "evidence-based medicine" is included although this filter does not
> attempt to provide comprehensive retrieval in that area. Review (PT) is
> not used as this would retrieve "non-systematic reviews".
> The supplementary strategy
>
> There are many articles in which the methodology describes a systematic
> review or meta-analysis but the author has not used these terms in the
> title or abstract, nor are they published in a specialized journal. In an
> attempt to include references to some of these studies the strategy was
> supplemented with additional search terms that rely on free-text searching
> for a combination of terms.
>
> The supplemental part of the strategy is made up of three sets of search
> terms:-
>
> * Terms that imply something has been done "systematically"
> * Terms used for the concepts of a review or overview
> * Terms for sources of date eg, literature, databases, trials
>
> The retrieval from the three sets are combined using the AND operator.
>
> Bringing basic and supplemental together
>
> * The basic strategy is ORed with the supplemental strategy
> * Letters to the editor, editorials, case reports etc are excluded as
> they are generally not of interest to clinicians looking for systematic
> reviews.
>
> Other sources of information explaining methods of locating systematic
> review articles have been provided.
>
>
> MEDLINE maintenance
>
> In general NLM performs two types of data correction. Individual
> maintenance where a single citation is edited to correct a specific error
> and class or global maintenance where multiple citations that share the
> same condition are all changed at once. Following the introduction of the
> DCMS system certain global changes can be done on a periodic rather than
> annual basis to the benefit of PubMed and the licensees. However for the
> time being MeSH changes will still be done on an annual basis.
>
>
> Cataloging changes for serials issued simultaneously in print and online
>
> In the spring of 2001 the National Library of Medicine adopted the single
> record approach in cataloging serials issued simultaneously in print and
> online formats. This means that NLM creates one serial bibliographic
> record in Locatorplus which contains information about both the print and
> online formats of the serial. NLM's single record approach is in accord
> with current CONSER serial cataloging guidelines. For serials indexed for
> MEDLINE that are issued simultaneously in print and online formats NLM
>
> * Assigns a single Title Abbreviation for both formats
> * Creates one catalogue record which will include both ISSN's
>
>
> TOXNET link added to PubMed sidebar
>
> A new link to TOXNET (NLM's Toxicology Data Network) has recently been
> added to the PubMed sidebar under Related Resources.
>
>
> New biological warfare website
>
> A new website on biological warfare, developed by the Division of
> Specialized Information Services at NLM, is now available. More
> information can be found at http://www.nlm.nih.gov/news/sisbiolwar02.html
> for more information.
>
> Reports of the Surgeon General available on the NLM website
>
> NLM has announced that it has made available all reports issued by the US
> Public Health Service Surgeon General at http://sgreports.nlm.nih.gov/NN/
>
>
> Key MEDLINE statistics available
>
> Key MEDLINE indicator information is now available on the NLM website at
> http://www.nlm.nih.gov/bsd/bsd_key.html. Statistical data are summarized
> by fiscal year.
