Dave Black dbo notes that we are not far from the five hundredth anniversaries of the Complutensian Polyglot (NT printed 1514; but not published until maybe 1521 or 22) and Erasmus' first edition (Novum Instrumentum, 1516).
Larry Hurtado is working on a project with SBL/BYU/Freer (mentioned here) to mark the centenary of the purchase of the Freer manuscripts in Washington (Freer site & byu page). Scheduled for SBL 2006.
Closer to home we have Mill's edition of the GNT published in 1707 (also the year of his death, exhausted after 30 years of work on the book). Someone in Oxford should really organise a conference to mark this.
I am waiting until 2013 to mark the two hundredth anniversary of the birth of S.P. Tregelles with a series of books and conferences (well, maybe a nice dinner).
What other anniversaries are coming up in the next ten years or so?
