Open Access (OA) scholarly communication means anyone, anywhere, anytime can read your work on the internet without the need for library journal subscriptions which create access barriers. No library can afford all the subscriptions its readers desire. The importance of OA is improved access to information which has been demonstrated to increase both downloads and citation rates thus visibility and impact. Increased visibility leads to increased chances of funding, invitations to speak at conferences, promotion, etc. Primary vehicles for delivering OA include: 1) OA journals; 2) OA archives or repositories such as arXiv; 3) posting on your own web page; 4) the so-called "author choice" option available with many subscription journals, e.g. Astronomy and Astrophysics. Many scientists at GI are already making their papers OA. Following a short overview of OA, a panel including (subject to availability) Uma Bhatt, David Newman, Steve McNutt and Nicole Moelders will discuss their experiences to date with OA.
