Obviously, the world Patrick O’Brian brings so vividly to life in our beloved series is complex and foreign to most readers. There is certainly no shortage of information about the time period and the novels themselves online (including over 250 articles on this site alone), but there are also many excellent companion books available. Your captain is a child of the internet age and so is not qualified to advise on any of them, but luckily the great Bruce Trinque (a POB/Age of Sail scholar and expert) compiled a fabulous list at Amazon.com. The list can be found here in its Amazon incarnation, complete with links to purchase each recommended book. I’ve included the list and Mr. Trinque’s comments without links below for your reference.
