That shows how outdated my McMaster-Carr catalog is. It only has 3,120 pages. Their web site is good enough now that I haven't bothered to ask for a new printed catalog for several years.

Another outfit with an impressive catalog is MSC Industrial Supply. Again, good web site design means that I seldom bother with their massive printed catalog.

Another neat outfit is Small Parts. Must have their printed catalog, because their web site, IMO, stinks.
