To enable better machine interoperability, we have added a way to get document summaries in XML format.  To do this, simply add "&xml=true" to the URL line of any document summary page. Here is an example.

We have just released a major update to the CiteSeerX service.  The most significant changes are under the hood, including better citation matching and improvements to the data model; however, there are several new features and UI improvements that may prove useful.

Specific enhancements of note include the following:

• BibTeX records now appear on document summary pages for convenient copy/paste access.
• All document file formats are now downloadable.  This means that if a document started as PostScript and was later converted to PDF, both formats will be available.  However, if a document was originally found in PDF format, only the PDF will be available.
• Self citations are now tracked.
• All search queries can now be converted to ATOM and RSS feeds.  This feature is particularly handy when combined with the advanced search form.  For example, you can track new content by author, institution, or text phrase or track new citations to individual papers and get updates right in your email inbox.  Look for the ATOM and RSS icons on search result pages.
  
• MyCiteSeer has gone through several upgrades.  For example, Bulletin announcements now show up on the account landing page and some new features have been added to the collections module.

Next on the agenda is enabling user corrections to document metadata and bringing the submission system online.  We are working to add these features as soon as possible.

As always, feedback is welcome.

CiteSeerX will be operating at reduced capacity the week of July 7th while we implement some major service upgrades.  Mostly, this will involve backend work to improve citation matching and data organization, but there will be several minor UI enhancements when we are finished.  Another announcement will appear when the process is completed.
