OK, ok, one more not-strictly topic map item and I promise no more for today!
Buy 2, Get 1 Free at O’Reilly caught my eye this morning.
I think it is justified to appear here for two reasons:
1) It has a lot of books, such as those on databases, that are relevant to implementing topic map systems.
But, just as importantly:
2) The O’Reilly online catalog illustrates the need for topic maps.
Look at the catalog listings under Other Databases for MongoDB (you may have heard about it). Now look under Database Design and Analysis. Opps! There you will find: MongoDB: The Definitive Guide. (at least as of 13 February 2010, 7:01 AM Eastern time)
One way (not the only way) to implement a topic map here would result in a single source of updates across the catalog. And the catalog could also act as a resource pointer to other materials. The Other Resources for the MongoDB book, isn’t terribly inspiring.

PS: I am hopeful the interest in NoSQL will drive greater exploration of MySQL, PostgresSQL and Oracle databases in general and as part of topic maps systems in particular.
