this setting controls whether HTML
tables are to be used when formatting results or whether
preformatted text should be used instead. Preformatted text
transfers much faster than tables, but it does not provide all the
Retrieval Options.

Use multiple windows

check Yes to have full
bibliographic records displayed in a separate window.

Preferred article format

when following a link to a
full-text article available from a third party, you can
specify whether you prefer to retrieve the article as
a PDF or PostScript file (when the option is available)

Preferred language

when viewing full
bibliographic records in the ADS, this is the language that
the document will be translated to when you follow the
link Translate Abstract

4.2.2 - Specifying A Proxy Server

Users working at institutes which provide access to external
databases and publishers via URL-rewriting proxy services can
specify the URL of the proxied ADS abstract service in their
preferences so that all links that they follow to resources outside
of the ADS website will be properly proxied. In order for this
to work you have to know your library or IT department must have
set up a proxied host for the main ADS server name
(or the equivalent mirror site).
If this is the case, specify the corresponding URL in the
proxy server field and all your queries outside of the ADS will be
properly handled by it. A similar approach can be accomplished
through the use of a Library Link server.

4.2.3 - Selecting Mirror Sites

Records in the ADS databases link to millions of related datasets
available from several providers. In some cases, the providers may
make these datasets available from different sites. The ADS provides
users with the option to select which mirror site should be used when
linking to a resource available from several sites. In order to do
this, simply use the proper pull-down menus to select the appropriate
site. For faster service, we recommend you select a mirror site that
is closest in location.

4.2.4 - Selecting the Look of Returned Pages

This section allows users to change the default colors in the
generated pages which are used for background, foreground, text,
links, and highlighting. You can also choose to modify the default
font size. A Color Table
can help you in selecting color values for these preferences.

4.2.5 - Reference Formatting

The reference formatting capability allows the user to specify a
format in which a bibliographic reference is returned.
Users can either select one of the pre-defined formats that we
provide, or create their own.
The predefined formats are:

MNRAS
-- Used to prepare papers for Monthly Notices of the Royal Astronomical Society

Link -- used to create hyperlinks to be included in HTML documents

If you desire to specify your own format for bibliographic references,
you may do so by selecting the Custom format entry and entering
the proper format. The format is described in the section
ADS Custom Format.

The user can select which journals should be included on this form
from the bottom of
the Preference Settings Form.
The user can specify the ones to be listed or excluded on the
ToC Page by checking or unchecking the box associated with the
corresponding journal abbreviation.
