It is self-evident that the more an author puts into a story, the more a reader will get out of it. Solid research will underpin the credibility of what lies between the covers of a book but and help build the trust of readers.
Research leads to writer-confidence in relating key information or capturing the atmosphere of a setting. More than that, it informs the reader by adding to his/her knowledge bank (no matter how subliminal). To do it properly, however, requires a balanced approach and an eye for what is important as opposed to what can be little more than window dressing.
I was once told that just because you know the detail of something doesn’t mean you have to bore the pants of everyone by telling them how clever you are. It’s all very well, for example, that you may know the precise calibrations and mathematic formulae for manufacturing a car engine but do your readers really want to spend time reading about it in a romantic novel, or, for that matter, any other kind of novel?

I like to read a lot of historical fiction. It's wonderful when the author manages to recreate the atmosphere of the past, and transports you to a different time. However, some authors get a little carried away. I personally, find it boring when there are too many details. I don't really need three paragraphs describing the beauty of the sunset or the crashing of the waves. A couple of sentences will do. Same goes for political situations and battles. A great book has just the right amout of information, without going overboard.
