The American Society for Indexing is an association committed to improving the quality of indexing and serving the needs of indexing professionals. Membership is open to all individuals interested in indexing, including: indexers, editors, technical writers, publishers, librarians, and anyone else curious about the profession and its workings.

The Chicago/Great Lakes Chapter serves members primarily from Illinois, Indiana, Wisconsin, Michigan, and Ohio.

We hold regular meetings and workshops to help educate and inform our members. Past events are described on the events page.
