Advance is published twice a year. Most editions contain a selection of Issue Briefs produced in the preceding several months on a range of topics of interest to the different Issue Groups. Other editions contain a series of papers on a particular topic emanating from a conference or symposium hosted by one of the Issue Groups. All pieces in Advance are substantive yet accessible, in order to be useful to practitioners, policymakers and the general public.

In keeping with ACS' mission, Advance does not endorse any single policy prescription, seeking instead to encourage debate among those who share ACS' commitment to the fundamental principles of human dignity, individual rights and liberties, genuine equality and access to justice.

ACS Issue Briefs -- those included in Advance, as well as others available in the ACS Publications Library -- are intended to offer substantive analysis of a legal or policy issue in a form that is easily accessible to practitioners, policymakers and the general public. Some Issue Briefs tackle the high-profile issues of the day, while others take a longer view of the law, but all are intended to enliven and enrich debate in their respective areas. ACS welcomes inquiries and suggestions from its members about potential Issue Briefs. To explore the possibility of writing an Issue Brief to be distributed by ACS, please email C21@acslaw.org.
