The new site features and enhancements include:
- RSS feeds
- Flash® animations
- Image galleries (including images that can be saved to your personal space on the website)
- Federated searching
- OpenURL (we will be able to use this once we have our serial solutions installed early next year)
- Brand new fast, sophisticated search capability
At the heart of the new web site is the new semantic search engine. Semantic Search improves upon traditional research searches by leveraging XML data in order to increase relevancy of results. (More information about this under Search below)

Navigating the Site
To return to the Home Page from any page on this site, click on the AccessScience logo in the upper left corner. (This is an acceptable web standard used in most of our databases).
Content can be browsed two ways – via topic or alphabetically – from the home page. To browse by topic, select from among the 19 high-level topics on the home page, choose a sub-topic, and a list of all topics within that area of study will be presented. Selecting one of these topics will display a page with links to all the information on that topic available within the site’s extensive collection, including encyclopedia articles, Research Updates, dictionary definitions, and multimedia content.
The alphabetical (A-Z) browse functionality is available both on the Home page as well as at the top of all internal pages. Click on any letter to see a list of all topics covered on the site. Click on a topic and you’ll receive a page with links to all the information on that topic available on the site.
Explanation of the Icons
AccessScience Topic pages are organized by the kind of content available on a given topic, which can include the following:
The AccessScience search engine was built to allow the user to easily discover the wide variety of information the site has to offer on the multitude of topics covered.
In addition to the approximately 7,000 articles in The McGraw-Hill Encyclopedia of Science & Technology, the site features Research Updates, news articles, biographies, dictionary definitions, multimedia, and other useful assets. The search features of AccessScience are built upon the semantic data associated with all of these articles and other assets.
Semantic data is information that has been categorized so that knowledge itself can be processed instead of text, thereby enabling more meaningful search results. For example, a search for “NH3″ might not normally return results, but because we have semantically associated “NH3″ with the synonym “ammonia”, a search for “NH3″ will return results for the topic “ammonia”.
If a default search results in a semantic match, results will be displayed on a “topic page” showing relevant search results from all areas of the site. Simply clicking on any of those assets will show the full content.
However, if a search term does not match an existing topic or one of its synonyms, the site will automatically perform a full-text search for your entry, and deliver the results for your review. A full-text search returns instances of words within all assets, rather than assembling only information with meaningful relations.
The titles of the Encyclopedia and Research Update articles are the backbone of the site; if your search request matches up to one of these “root” terms or one of its synonyms, you will be taken directly to a page that has assembled all content the site has to offer on that topic. If your search is a close match, you may be asked to confirm your selection before being taken to the topic page. A spell checker is included to verify your input and if necessary suggest alternatives.
If a search matches multiple topics available on AccessScience, you will be asked to choose between those multiple possible matches, or you can choose to do a full-text search on your search term.
In addition to the default search functionality, searches can be customized in a number of ways by clicking on the “Search Options” link next to the search box on every page of the site. Under these search options, you can choose to do a full-text search, bypassing the semantically-driven topic search. You can also search within only specific asset types, content areas (encyclopedia only, for instance), or any of the 19 high-level topics (Chemistry, Mathematics, Physics, etc.) available on the site.
