Exactly, Wilfred.

The card catalog was the most efficient product we had until the computer catalog came along. And the computer catalog, with the ability to deal with misspellings, incomplete queries, instant updating and indexing, and multiple users querying the same thing at the same time is as superior to the card catalog as the card catalog was to the book catalog.

Computers have allowed librarians to go back to being librarians, to helping the users, instead of doing endless, mind-drugging, repetitve tasks. You don't need a graduate degree to file catalog cards, but it sure comes in handy when someone asks you how to go about mummifying a squirrel (as I have been asked) or whether or not a new "artificial blood" can pass through the placental membrane (and I've been asked that, too).
