It is a pleasure and an honor to be able to introduce this, the second issue of Code4Lib Journal. See: http://journal.code4lib.org/ Each article in this issue has a little bit of something for all who call themselves a librarian or work in a library. Each identifies some sort of library problem to be addressed, and offers one or more solutions. Many are complete with code snippets. After all, this is Code4Lib. For example, people in public service may be interested in Edward M. Corrado and Kathryn A. Frederick's review of database-driven subject guide applications. Kenneth Furuta and Michele Potter describe a simple help system that brings librarians running to the reference desk. Margaret Mellinger and Kim Griggs explain how library resources can be organized into course pages without the need of HTML knowledge and yet sport Web 2.0 features. Nancy Fried Foster, Nora Dimmock, and Alison Bersani shed light on participatory design. For those of us who enjoy cataloging and metadata issues, Jonathan Gorman outlines how he modified VUFind to exploit Wikipedia and cataloging authority records to enhance information about authors in a library catalog. Chris Freeland, Martin Kalfatovic, Jay Paige, and Marc Crozier illustrate a different use of Library of Congress Subject Headings by integrating place names with Google Maps. Carol Jean Godby, Devon Smith and Eric Childress describe a technique for crosswalking just about any metadata format into just about any other metadata format. For the systems librarian in you, Dan Scott and Kevin Beswick share how they used Linux live CDs customized as kiosk browsers to provide laptops as 'quick lookup' stations at their library. Andrew Darby takes advantage of the Google Calendar API to easily manage the display of library hours. Jody DeRidder exploits Google sitemap technology and static HTML pages to make content in the "deep Web" more accessible. We hope you find these articles useful, stimulating, and relevant to your daily working lives. -- Eric Lease Morgan University Libraries of Notre Dame
