This workshop is part of a multipart Digitization Series produced by Infopeople with sponsorship from the California Digital Library and Online Archive of California. Courses in the series include "Managing Your Digitization Project (online)," "Introduction to Metadata and Record-Building (online), and "Encoded Archival Description (hands-on)." Courses in this series may be taken individually. Each course covers different material.
These workshops are designed to help California libraries develop and implement digitization projects, including projects funded through LSTA grants administered by the California State Library.
In today's library, scanning images both to preserve them and to make them more broadly accessible is a natural step in collection development and maintenance. If you're thinking about getting started with scanning, this workshop will bring you up to speed on questions such as:
- What scanner is appropriate for my project?
- How do I protect my fragile archival material while scanning?
- What are master and derivative images?
- What are pixels and pixel resolution, and what resolution is right for my images?
- What do I need to know about scanning standards and metadata?
When you begin scanning for preservation and access, you must take control of the quality of your images. In this workshop you will learn how to select a scanner, to manage the scanning process, and to understand, choose and implement appropriate scanning standards. This course offers many practical and useful tips that can be applied immediately when scanning in your institution, at home, or when outsourcing to a vendor.
Workshop Description: This hands-on workshop provides an overview of the scanning process with special emphasis on the techniques that must be employed when scanning cultural heritage collections. Through hands-on exercises (using scanners, scanning software, and the Photoshop graphics program), you will learn how to adjust light levels, batch process images, and make the scanning process run smoothly. You will create master archival images as well as derivative images suitable for access on your website or via the library's online public access catalog. You will also be introduced to the California Digital Library's imaging standards in order to learn how to implement industry standard best practice guidelines for imaging.
