In 2007, I wrote a post titled My XBRL Reading List. Take out my window dressing, and you had a pretty short list. Two years ago I did a post that added more materials, but it was still relatively scanty.

Since then, as XBRL adoption has expanded, resources both on and off the Inter have increased substantially. I wouldn’t call it an embarrassment of riches — for example, there are still few XBRL books — but certainly there is a healthy flow of information and mmentary on interactive data developments from numerous sources. 

As I noted in my post on social media, monitoring Twitter Search results for XBRL will keep you up-to-date on most XBRL-related blog posts, articles, and events — an objective that can be aided by creating a Google Alert for XBRL or a search on that term at Google Blogs.

One resource these searches may easily miss, however, is the Yahoo Group XBRL-Public.This is one of the the oldest XBRL resources on the Inter, and it still offers the best forum for debating XBRL issues. The recent thread on Building an Inhouse XBRL Viewer is a vigorous clash of opinion among the best minds in the field. The thread’s title doesn’t do any sort of justice to the robustness of a debate that centers on Inline XBRL, but ranges from the potential of the Semantic Web to the perverse utility of white fonts for information camouflage.

At the same time, XBRL novices can expect urteous assistance from this group. Just yesterday, Charlie Hoffman provided a list of sources for someone who does not know “the first thing about it.”

I’ve provided Inter and print resources below that offer the latest XBRL news and mmentary, as well as more permanent ntent such as taxonomies and primers. Relative newmers will probably find it most useful, but I hope long-time practitioners also disver one or more entries worthy of subscription or bookmark.  I’m sure I have omitted useful resources through oversight or ignorance; readers should feel free to suggest their favorites in a ment.
