1 Link farm
This page contains handy links categorised and fairly densly populated for fast, repeated access to primary and secondary sources. The primary sources are often large downloadable tomes of higher quality/authority while the secondary sources tend to be predominately html pages related to or derived from the primary sources, but which might be better for getting the info you need quickly. The secondary links may duplicate each other to some extent, depending on user preferences.
