Free searches are very limited as to the results.  A free search people by cell phone numbers is not provided for students, but searching classes and personal consultations are available to help students learn how to search various databases.  Free searches are wide-ranging with loads of detailed criteria to select, as well as narrowing the locality down to within 5 miles.  They are available online, but document copies require registration and a fee.  Free searches are out there, but data must be paid for through a subscription service or the purchase of a CD-ROM.  Free searches are available for references through 2005.  Many of these free searches are instant.
