Two great products, one small portable, universally accessible drive.  A large chunk of forgotten past and current human knowledge loaded onto one external USB hard disk drive. Designed to keep you informed and educated whenever and wherever the Internet is not available.  This would be a great reference or educational tool. Many of the thousands of books included here have been long out of print.  To ensure long-term viability we used hard disk platter drives, designed to retain data without needing power as modern SSDs require.  Each drive is tested and guaranteed to work on PC's, Mac's, and Linux machines, any OS (Windows XP through 11) and any model.
