In the two years since WP:60 launched, we have delved into many important points from Wikipedia's Manual of Style (MOS). But the main Manual of Style is not Wikipedia's only guidebook. Additional Wikipedia style guides go even deeper, covering specific sections of articles, article topic areas, and how to resolve discrepancies between style guides.
In the infobox on the main MOS article, you can browse style guides by topic area. That's where you'll find Wikipedia standards for editing articles on Television, Mathematics, anything Ireland-related, among others. There are style manuals for infoboxes, biographies, text formatting, article layout, you name it.
Wikipedia's Manual of Style is huge; no one can memorize the entire guideline. As the MOS says, it is "a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply".
