  The NASA Astrophysics Data System (ADS), a critical research service for the
astrophysics community, strives to provide the most accessible and inclusive
environment for the discovery and exploration of the astronomical literature.
Part of this goal involves creating a digital platform that can accommodate
everybody, including those with disabilities that would benefit from
alternative ways to present the information provided by the website. NASA ADS
follows the official Web Content Accessibility Guidelines (WCAG) standard for
ensuring accessibility of all its applications, striving to exceed this
standard where possible. Through the use of both internal audits and external
expert review based on these guidelines, we have identified many areas for
improving accessibility in our current web application, and have implemented a
number of updates to the UI as a result of this. We present an overview of some
current web accessibility trends, discuss our experience incorporating these
trends in our web application, and discuss the lessons learned and
recommendations for future projects.
