Loyalty, Database

A librarian should never commit to one library database vendor/interface. Eventually that vendor will merge with someone else, leaving you with an outdated Wilson Web logo tattooed on your midriff.

Vendors, Hating

Librarians should not hate library database vendors. Yes, they dress better than you and they get paid more than you, but they are miserable soulless people who deserve your compassion. Plus, they give you free ink pens.
