a brief history of library automation

“ disconnected data silos with non-usable content”

worldcat : 1 billion records

learning from taxonomies

classic problems in authority control spell-check stemming synonyms phrases anachronisms

disambiguation

Definition

expertise can be efficient

topic depth (faceting/subdivisions)

lessons from folksonomies

don’t scare off your workforce

in the short term, satisficing trumps perfecting

In 2006, 400 catalogers at the Library of Congress cataloged 350,000 “volumes.” That’s 1,400 records per workday, or 3.5 records per person, per day.

Tagging is about (re)discovery and (re)use, not (just) description

Tagging is about building data, not records

folksonomies grow good metadata

90% of Flickr content falls into 6 different types of facets: place (40% of tags), events , dates, people, things/animals, color

some basic rules about cataloging appear instinctive

Useless critiques of folksonomies

problems common to taxonomies and folksonomies tags * time = crud scalability (onesies vs. noise)
