HOW TO NAVIGATE THIS SITE
Resources

There are four basic categories of pages on this web site: Events, People, Places, and Science and Technology. These are further divided into sub-categories, each with its own introduction.  Categories and sub-categories can be accessed by clicking on a button to your left.  If you would like to begin with a quick survey of the Manhattan Project, try reading (in order) the eight Event sub-category pages, beginning with "Atomic Discoveries, 1890s-1939." For thematic lists of pages drawn from all four main categories, see the "Special Topics," and under "Resources" you will find a collection of supporting material.

When completed, The Manhattan Project: An Interactive History will total some 120,000 words and over 200 pages and 500 images, including photographs, maps, and drawings.  The site is being implemented incrementally, with the "Events of the Manhattan Project" and "Resources Relating to the Manhattan Project" sections the first part to go online.  Click on the Events or Resources buttons to the left, or visit the Site Map, for a listing of currently available pages.  

This web site is best viewed with Internet Explorer. Bulleted lists sometimes are displayed with extraneous blank lines when viewed with some versions of Netscape Navigator.  Whenever you see text that is underlined and in bold, such as this, it is a link that points to another page on this web site.  Normally a term is made into a link only the first time it is mentioned on each page.  Whenever you see text that is underlined but not in bold, such as this, it is a link to a web page external to this web site.  (This usually only occurs in the "Suggested Readings" or "Sources and Notes" for each entry.) Text that is in bold but not underlined, such as this, is a link to a page that is not yet available.

To learn more about any particular photograph, simply move the cursor over the image and leave it there for a moment (a caption will appear). Source information for photographs and other images is in the "Sources and Notes" for each entry.  Click on any photograph to view a larger version of it (if one is available).  Some photographs have their own web pages with further background information; a list of these "photograph pages" is available in the "Photo Gallery.
