In my experience, people do not understand what it means to search by “title” “author” or “subject”. And they don’t care to learn. They like keyword because it is what they are used to. And then the problem becomes: how do you arrange keyword results?

Since I am an historian I try understand what is happening from a historical point of view, so I like to go back into some of our beginnings. Why did Cutter … [et al.] make something they called a *dictionary* catalog as opposed to something else? For them, the choice they had was called a “classed catalog” but I won’t discuss that here.

Cutter … [et al.] wanted to build something that was the easiest to use for the public of their time. This was discussed widely. At least in the US, they decided that almost anyone who walked into a library would know how to use a dictionary. So therefore, they arranged everything in alphabetical order so that if people wanted things on “dogs” they would look under “D” and go past “Da” “De” “Di” etc. and finally come to the items on dogs, or a cross-reference to look someplace else. In other words, they made it work like a dictionary.

Of course, that means they made it work like a *19th-century* dictionary. Today’s online dictionaries work completely differently because they have been re-designed to work in a radically different environment: keyword, where you just type in the word to the best of your ability and see what happens.

The farther away we get from Cutter’s world, the less sense lots of his rules make. I am wondering how long it will be before (those very few) people like me who study the history of cataloging and come across the title “Rules for a Dictionary Catalog” will have completely forgotten what the “dictionary” part means, and how those rules assume the use of something called “alphabetical browsing” and what that means. If you don’t understand alphabetical browsing, many of those rules make no sense at all.

Yes, I extend this same thinking to many of our practices today. Much of what we do is still based on the dictionary catalog, which has become completely obsolete. It was something I hoped AACR3/RDA would really address.

Today, people have experience with the Googles and they expect our tools to work like something from the 21st century, not like tools from the 19th-century. The Googles do not have choices by author, title, subject and are all keyword searches. Keyword results have to be arranged in some way, and for all its faults, “relevance” is probably the best choice at this juncture.

For an older article on relevance that was widely discussed see: http://www.alatechsource.org/blog/2006/03/how-opacs-suck-part-1-relevance-rank-or-the-lack-of-it.html
