For me, getting involved in Zen practice has involved a lot of reading to help myself get up to speed reasonably quickly. Here's my suggested reading list, in recommended order (which is not necessarily the order I read them in):
The Classic. Required reading if you're planning to practice at Zen Center. Seriously, if you're reading this blog and haven't read this stop right now, got get a copy and come back when you're done.
A collection of short, easily digestible, quotes and anecdotes of Suzuki Roshi. A good one to have handy for idle browsing or if you want a quick something to ponder.
Not by Suzuki Rosh, but an account of his life and the early years of SFZC. Full of stories that really help to make sense of some of the particularities of life and practice at Zen Center. My favorite is about how the first rule at Tassajara is that brooms should be stored with their bristles up, and every time I've opened a broom closet (which turns out to be a lot) I've found them stored just so.
Another collection of Suzuki Roshi's talks. It's only available in print right now so it might take me a while to get around to finishing.
Some of Suzuki Roshi's last lectures, discussing the Sandokai which is chanted on a regular basis in services, and particularly during memorials. I'm about half way through so that the first half of the chant is filled with meaning and the second half is still a bit of a mystery.
Reb is the most senior teacher at Zen Center and lives at Green Gulch. His two books cover the precepts (which you'll want to read before asking to take the precepts and getting permission to start sewing a Rakusu) as well as a collection of Dharma Talks he's given over the years.
D.T. Suzuki is a well regarded Buddhist scholar who wrote some of the first english texts on Zen. He's primarily concerned with Rinzai but these texts are what brought a lot of people to Zen Center in the 60s and 70s so they're helpful in understanding the early history of the lineage and some of the details of practice.
