SV may be the first technique/method that is better supported through websites than the more traditional cookbooks. I've picked up a few cookbooks along the way, "Under Pressure" by Keller is good, (great pics), a few others are not bad. Not a fan of Baldwin.
When I want to try something new I start with Chef Steps and Serious Eats web sites. Chef Steps even has a couple free on-line SV classes that will help establish basics. Each of the manufacturers have websites with recipes and techniques, Anova is good, Sansaire and Sous Vide (the company) are so so. Favorite is Nomiko - you'll want to be on their email list even with a different machine.
There are several users here, any specific questions will probably be answered. Not always correctly.
Enjoy.
