Publication: National Academy of Sciences (U.S.) _Biographical Memoirs_ online
The National Academy Press (NAP), publisher for the National Academy of Sciences (U.S.), has mounted HTML and PDF editions of 264 of its Biographical Memoirs online at: http://www.nap.edu/readingroom/books/biomems/ I don't know if access to these requires licensing/subscription by your institution (i.e., your domain name--such as "ucla.edu"--would be automatically read and checked against the NAP permissions database before you are allowed access), but you might want to check out this resource to see if it works for you. --Russell Johnson
