This page was the online home of the book based on the 2007 Talbot workshop,
edited by Chris Douglas, John Francis, André Henriques, and Mike Hill.
The book has now been published and is available from the AMS
here.
A preliminary pdf version of the book may be found on the editors' webpages,
cld, jnkf, agh, or mah; note that numerous corrections were made between that and the final printed version. The table of contents of the book is as follows.

Glossary.
A few pictures that appear in the book:
Adams spectral sequence
Ext_{A(2)}( F_{2} , F_{2} ) ⇒ π_{*}(tmf).
The Adams Novikov spectral sequence for tmf [by Michael J. Hopkins, 1993]
Elliptic spectral sequence
H^{q}( ℳ_{Ell}‾; ω^{⊗p} )
⇒ π_{2pq}(Tmf)
