The federal Grants.gov web site has been redesigned. According to a notice posted on the site, although “the look and feel of the site will be different, the content and its functionality will remain the same.”
One change is that funding program announcement links now have different URLs, so if you are looking for a specific previous funding program, you may need to use the Grants.gov search to find it again. One improvement to the redesigned site is that the search now features faceted searching, so that you can select different categories on the left menu to refine your search results.
