Alphabetization

Before alphabets came into use, a complex system of pictographic symbols were used to store written information. The first alphabetic writing system, a Proto Sinaitic script with consonants, is believed to have been developed between 1850 and 1700 B.C. by a group of Semitic-speaking people. The script comprised 22 symbols and were written from right to left.
