Apologies for crossposting
Summary of latest completed National Library of Medicine Technical Bulletin
below, from my colleague Stephanie Brockhouse. Full Bulletin via
http://www.nlm.nih.gov/pubs/techbull/ma02/ma02_issue_cover.html.
More points of interest than usual, at least to me. Hope will be to others.
What do you think of the PubMed tutorial, by the way? I find its useful in
that its on the PubMed site, and kept more up-to-date than the alternative
ones. But a bit complex to navigate for anyone not very into web use, and
needs Flash...

A further NLM Gateway release
A further Gateway release has recently taken place and details of the latest
changes can also be found on the Gateway sidebar under the What's New
heading.
Briefly the changes include additional search fields being displayed now the
results are retrieved from the PubMed XML output. Other changes relate
mainly to window size, cursor positioning and a name change for DIRLINE.
Why citations to older articles may display before more recent ones in
PubMed
Following a number of enquiries regarding the above NLM have explained that
PubMed's Entrez date, and when citations are added to the database,
influences order of display.
PubMed results are initially displayed in reverse chronological order of the
Entrez date ie. last in, first out. If required, search results can be
sorted by publication date using the system Sort feature.
Citations are usually added to PubMed soon after publication although this
is not always the case. In certain circumstances the Entrez date for older
citations is noticeably more recent than the publication date.
Patient Education Handouts in MEDLINE/PubMed
Some journals have begun publishing summaries intended for patients or the
lay public to explain a procedure or condition, or perhaps summarize or
comment on articles that report scientific or medical findings in the same
issue. These summaries are designed for physicians to share with patients
or to assist physicians in talking to patients. Starting in 2002 patient
summaries are indexed with the new Publication Type - Patient Education
Handout.
For handouts that summarize other articles NLM have now created links,
similar to "comment" links, between the Patient Education Handout citations
and the citations to the full articles that they summarize. The links will
appear in PubMed with the text "Summary for Patients In" on the original
article citation, and "Original Report In" on the patient handout citation.
CCRIS, ChemIDplus, DIRLINE, Gene-TOX,HSDB. and TOXLINE Special now

The National Library of Medicine has announced the distribution of CCRIS,
