I'd recommend starting with a reputable history of the druids, such as Ronald Hutton's Blood and Mistletoe The History of the Druids in Britain or his The Druids: A History which is essentially a condensed version of Blood and Mistletoe .
There are also groups such as The Order of Bards, Ovates and Druids (www.druidry.org) and the Druid Network (www.druidnetwork.org) who offer training courses and material, though do bear in mind that we know very little about the practices and beliefs of ancient druids therefore modern druidry is an interpretation of rather than a continuation of druidic practices.
If you're interested in Celtic folklore and a more reconstructive form of practice you can take a look at CR groups like Paganachd; http://www.paganachd.com/
The groups mention above are good resources. I'm a Bard in the Order of BArds Ovates and Druids and can say it's a great program, however not everyone can afford it.
The Ancient Order of Druids in America (http://aoda.org/) is another great group which is cheaper than OBOD and based in the US.
An even cheaper alternative still is ?r nDra?ocht F?in: A Druid Fellowship (https://www.adf.org/) which is a more recon Irish influence group. It's very affordable for membership.
Another great group is the Black Mountain Druid Order (http://groveoakorg.ipage.com/) which is revamping itself as Order of the Taibhsear with more shamanic influence. I've also done their dedicant course which is 100% free.

Druidry is like any other path ..what do you expect to gain from the path .if nothing then why choose . if you choose a path it is because you already have an expectation of where that path will lead you! Just my opinion of course.
