I use this extensively rather than re-inventing the wheel.
Paul Grundy, the admin, keeps it up-to-date and welcomes any corrections or new information, especially in a well-written article, supported by WT publication quotes.
Don't be frightened away by the material being more than 3 paragraphs. The quotes from WT publications is are extensive and from publications that are older and less available.
I find it good to read many posts on a single topic and expand my knowledge and sources.
