profile
Books 24x7.com stores publishers' content in an XML-tagged format that allows sophisticated searching.
copy protection
Content is maintained on a Books24x7 server. Though printing pages as copy is being read is permitted, downloading content files is not. Copy is password-protected; only one person can use a log-on password at any one time. Log-on from multiple computers or locations is permitted, but still only one user of a password can log on at a time. Books24x7 watches for abnormal patterns that might suggest users are copying material or giving away a password--such as log-ons from too many IP sites too quickly, or too many pages per minute being accessed or printed. If severe enough, further access is denied.
