 * Wikipedia prefers citations to reviews and books, not primary journal references (tens of thousands appear annually). Citing secondary sources is the encyclopedic style.
 * Do not cite yourself or your colleagues. It's called conflict of interest.  Many new editors cite themselves mainly.  That behavior is not appropriate.
