2.9 - What's New Service
The ADS Abstract Service has the capability to search the database for
recent entries. This service allows the user to conduct searches of
the abstract database for all new abstracts which fulfill his or her
favorite query. The service can be used through the WWW or through
email, and can be automated to return all new entries within a
specified period (such as the last month).
To use this service follow the following steps:
1.
Build the query:
- Use the WWW interface to build a query by repeatedly
executing it until the desired result is returned. If
you do not have WWW access, you can request the query
form by sending email to adsquery@cfa.harvard.edu
. help in the
message body will provide some
assistance. To get a query form, the message body should
include:
action=http://adsabs.harvard.edu/abstract_service.html
method=get
return=form
- This returns the form with hyperlinks surrounded by "@"
signs. To follow a hyperlink, uncomment the appropriate
one in the section which begins Start of hyperlinks.
To submit the form, fill out the form in the section
which begins with Begin of Form 1 by filling in search
criteria after the "=" signs.
2.
Save the query form:
- Request that the query form be returned for this query
by selecting Return Form in the Build Query Form
section below the send button. A negative number in
the Entry Date day field determines how far back the
query goes. For example, to get any entries in the last
month, use -31.
3.
Use the form:
- This form can be used either through the WWW by opening it
in the browser (or saving it in your hotlist) with the syntax:
file:/directory/filename
- or it can be used to execute an e-mail query by typing:
mail adsquery@cfa.harvard.edu < /directory/filename
- If you are on a Unix machine, you can set up a crontab
file which will automatically send this email message
at specified intervals. To enable this feature, edit
your crontab file by issuing the command crontab -e
and entering the following:
0 24 1 * * mail adsquery@cfa.harvard.edu < /directory/filename >/dev/null
- where /directory/filename is the name of your saved query file.
- This will execute the query on the first of every month
and query back for 31 days (if the day field contains -31).
