Problems:
  As good as each piece is,
  the whole is:
  Incohesive
  Hard to find
  Inadequate as a cookbook for beginners
Possible Solutions
Write a book:
     a substantial achievement,
     but you have to finish them,
     they are hard to update, and
     expensive.
Create a central web site that points to other resources:
     easy to do,
     but content will be inconsistent
     and therefore hard to follow.
Write an online book:
     but what does that mean,
     is it a Wiki,
     a collection of pdf files,
     or what?

Synthetic Seismicity Catalog Production -
Andy Michael, Agnes Helmstetter, Karen Felzer

Authoritative
1. Known, expert authors
2. Peer review with an editorial board
3. Editorial board oversight of Wiki and forum
4. Basic science must be previously published in a peer
reviewed journal
5. Provide ways to benchmark codes
Up-to-Date
1. Updated on an annual basis
2. Schedule gives authors deadlines
3. Schedule provides time for peer review
 Prominent
1. Articles in Eos and SRL
2. Presentations at meetings
3. Provide clear guidelines for citing CORSSA
 User-Friendly
1. Encourage use of data format standards.
2. Encourage development of portable codes.
3. Encourage development of stand-alone codes rather
than using Matlab or other commercial packages.
The Key Word in CORSSA
Is
Community
CORSSA’s goal is to improve the quality of research that
applies the methods of statistical seismology.
This will benefit the community but requires that you join us
to suggest articles,
to write articles, or
to contribute to the Wiki.
Please join us.
