The ADS provides access to over 940,000 references from astronomy and planetary sciences publications and 1.5 million records from physics publications. It is funded by NASA and provides free access to these references, as well as to 2.4 million scanned pages from the astronomical literature. These include most of the major astronomy and several planetary sciences journals, as well as many historical observatory publications. The references now include the abstracts from all volumes of the Journal of Geophysical Research (JGR) since the beginning of 2002. We get these abstracts on a regular basis. The Kluwer journal Solar Physics has been scanned back to volume 1 and is available through the ADS. We have extracted the reference lists from this and many other journals and included them in the reference and citation database of the ADS. We have recently scanning Earth, Moon and Planets, another Kluwer journal, and will scan other Kluwer journals in the future as well. We plan on extracting references from these journals as well in the near future. The ADS has many sophisticated query features. These allow the user to formulate complex queries. Using results lists to get further information about the selected articles provide the means to quickly find important and relevant articles from the database. Three advanced feedback queries are available from the bottom of the ADS results list (in addition to regular feedback queries already available from the abstract page and from the bottom of the results list): 1. Get reference list for selected articles: This query returns all known references for the selected articles (or for all articles in the first list). The resulting list will be ranked according to how often each article is referred to and will show the most referenced articles in the field of study that created the first list. It presumably shows the most important articles in that field. 2. Get citation list for selected articles: This returns all known articles that cite one or more of the articles in the first list. The resulting list shows the articles that cite the most articles in the first list at the top. The articles with the most citations are presumably the review articles in the field of study that created the first list. 3. Get also-read list for selected articles: This creates a list of articles that were also read by the readers of the articles in the first list. This list will show what articles are currently being read in the field of study of the first list and will give an idea of which articles are currently considered important for this field. Combinations of these second order queries (e.g. first a citation query to get the review articles, then a reference query to get all the references in the review articles) can further enhance the utility of this new capability. These capabilities provide unprecedented search capabilities that allow the scientist to search the literature in ways that have never been available in one system before.
