It would be great to get some contributions from a wider range of people. Here are some areas that are worth considering as possibilities to explore:

Biographical notes on significant numismatists of the past. The Asylum has printed quite a few already, but there are certainly many more individuals that haven't received attention. Just at a glance through Bill Malkmus's admirable index, I see that William Sumner Appleton, Isaac F. Wood, Montroville W. Dickeson, George W. Rode, C. W. Betts, and John Hickcox are among the important and/or colorful characters neglected.

Comprehensive reviews of the literature on a particular series or topic. (Thanks to David Fanning for this idea.) We've had recent articles on the Smithsonian's collection and Admiral Vernon medals, but I'm sure everyone who has a favorite series that they collect could say a lot about the past and present references on that series, or about the history of a major collection pertaining to it. This is especially true for things other than coins - medals, tokens, emergency or special purpose scrip, etc. - which often don't have the equivalent of Breen or Krause-Mishler.

In-depth book reviews. The E-Sylum is great for several paragraphs, but sometimes a book calls for a somewhat longer discussion, either because there's so much going on in it or because it's debatable on some important points. Again, I'm sure people have opinions that would be worth sharing in print.

Obituaries. Not something anyone really wants to think ahead on, but when the numismatic community loses someone important, there are times when there's more to be said than a few paragraphs in the E-Sylum. This is especially true if it's someone who has published notable numismatic works that are worth a bit of extra discussion as part of an appreciation of their numismatic achievements.

Google Books. There is a wealth of numismatic literature now available for free on the web via Google, but a guide to what is and isn't (yet) available would be very helpful.
