The authors are pleased to introduce the second pair of articles in the National Career Development Association (NCDA) Centennial Special Series celebrating the 100th anniversary of NCDA. In this issue, JoAnn Harris-Bowlsbey reviews the development and use of computer-assisted career guidance systems, and Juliette N. Lester, James Woods, and Burton L. Carlson discuss the National Occupational Information Coordinating Committee (NOICC) and State Occupational Information Coordinating Committee (SOICC) networks. These articles recount two significant tools that shaped NCDA's place in supporting the discipline of career counseling and advocating for policy to support career development programs at the local, state, and national level.
