I'm sure glad people collect stuff.
Collectors come in all stripes and colors and they collect stuff of nearly infinite variety.
The collector, in order to insure the preservation of the collection will often give or put the collection on deposit in a library, museum or archive. And we are all enriched. Now, thanks to the web, we can see parts of many of these collections. We are further enriched, as a culture, because of it. I love books, manuscripts, and artifacts of all kinds.
