May 19, 2008 - New Searches Available
The Library of Congress Online Catalog has been upgraded to a new version. The
most notable features of the upgraded online catalog are some new searches available through the Basic Search screen, as well as the ability to search the Holdings index from the Guided Search screen.
The searches are grouped with keyword searches listed first, followed by expert, left-match and browse searches (while most of the original searches remain, some have been renamed).
Keyword (match all words)* - searches all fields in the bibliographic record. The more words you provide in your search, the more relevant your results will be. Limits are available for this search.
Title Keyword* - is a keyword search across all subfields for all title fields. This includes subtitles, alternate titles, and the statement of responsibility. Limits are available for this search.
Author/Creator, Subject, Name/Title and Series Title - are keyword searches, across all subfields for authors, subjects, name/title and series titles heading fields (established headings).
Expert Search (use index codes and operators)* - is the new name for Command Keyword. There is no change in functionality. Search limits are available.
The remaining searches were available in the previous version of the catalog. Title Begins With (omit initial article)* is the title search where you must enter words from the title, starting the first word, in order (always omit the initial article). The remaining browse searches and number search are unchanged from the former version of the online catalog.
Other Features Added
The default number of results per page is now 100 (it was formerly 25).
Guided Search now offers three boxes for entering search terms (increased from two boxes).
A new index has been added to Guided Search for the Holdings information.
August 17, 2006 - Session Timeout Alert Implemented
The Library of Congress Online Catalog is currently set to timeout after 5 minutes
of inactivity. Timeouts are necessary due to simultaneous user
limits that must be in place in order to assure an acceptable level
of system performance. Previously, users received no warning prior
to session timeout.
The new "Session Timeout Alert" provides
the user with a continuous count down clock displayed
in the lower left-hand corner of the browser window in the status
bar, as well as a pop-up window alert that appears 1 minute
prior to timeout. From the pop-up box, users can easily refresh
the session and restart the 5 minute clock. In addition, if a
timeout does occur, the user will have the
option of restarting their session and returning immediately to
the most recent search conducted.
Special Note to Users of Screen Readers: The "Session Timeout Alert" feature is not currently recognized by screen
readers like "Window-Eyes." The Library is aware of this problem and is in the process of rewriting the
script for this feature so that it will be fully accessible to
all users in the near future.
Special Instructions for Firefox Users: In order to get the full
benefit of this new timeout warning feature, you will need to enable
the browser's status bar, which is generally off by default. To
do this, open the Firefox browser, select Tools, then Options and a pop-up window will appear (see below).
Make sure that the "Globe" icon (Content) is selected (shown above). Next, select
Select OK twice in
order to close both windows and save the update.
Special instructions for Opera Users: In order to get the full benefit of this
new timeout warning feature, you will need to enable the browser's
status bar, which is generally off by default. To do this, open
the Opera browser, select Tools, then Appearance, and a pop-up
window will appear (see below):
then select the Toolbars tab, enter a check in the Status Bar box, then select OK to accept the change.

Problems with Emailing Records
Bibliographic records with non-Roman scripts or characters can be emailed, however the non-Roman script characters will be replaced with dots in order to ensure transmission via email. Users may prefer to print or save records instead of emailing them.
Authority records with non-Roman scripts or characters can be emailed, but the ability to display the non-Roman scripts or characters may depend on the user's email system (authorities.loc.gov). Since not all email systems are capable of handling non-Roman scripts or characters, users may prefer to print or save authority records instead of emailing them.
