Source CollectionSource Collection

Mark Avery Photography: Photographs 1977-1994 consists of thousands of black and white 35 mm film negatives Housed at the Archives, UWM Libraries Finding aid available at:

http://www.uwm.edu/Libraries/arch/findaids/uwmmss155.htm

Mark Avery worked as the staff photographer for the Milwaukee Repertory Theater Company from 1976 to 1994

He donated his collection to the Archives at the UWM Libraries in 1999

Why the Mark AveryWhy the Mark Avery Collection? Collection?

Share a unique resource with a wider audience Archives at the UWM Libraries owns copyright to the

collection Increase the visibility of the collection and

encourage new scholarly use Improve access to the collection Create an online resource for the UWM theater

students, researchers, and community users Enhance intellectual control through indexing

and creation of metadata

Selection of ImagesSelection of Images

The most representative images capturing key scenes and characters of the play

The negatives were selected for scanning after careful examination using a light table

Images selected for all 195 performances represented in the Mark Avery Collection

17

Image CaptureImage Capture

Follow digital imaging standards Use-neutral approach Originals vs. intermediaries

Scan the photographic negatives at 4000 dpi resolution in grayscale mode using a Nikon 4000 ED film scanner

Create digital master files Save scan images as uncompressed TIFFs

Assign a unique name following file naming conventions, e.g. av00001

18

Image ProcessingImage Processing

Process images using Adobe Photoshop Remove dust marks and scratches Correct images for tone and contrast, when

necessary Save the changes in the working copy of

master TIFF file Create derivative (access) images for Web

delivery and save them in JPEG format

19

IndexingIndexing

The negatives filed by season and performance; no other indexing data available

A research process accompanied the creation of the digital collection

Cooperation between the UWM Libraries and Milwaukee Repertory Theater Company was established at an early phase of the project

20

ResearchResearch

Gather the indexing data: names of actors and characters featured in the images, play titles, authors, dates, names of other contributing artists, such as directors, costume and set designers, and lighting designers

Examine research materials (play scripts, programs, and photographic prints)

Consult with subject experts

Building an Online CollectionBuilding an Online Collection

In order to build an online searchable collection you need a digital delivery system

Possible solutions1. Develop an application in-house using a

generic database (e.g. MS Access, MySQL) + middleware (e.g. PHP, ColdFusion)

2. Purchase a digital management program, e.g. CONTENTdm or Luna Insight

3. Use an open source digital library software, such as Greenstone (New Zealand) or DLXS

CONTENTdm: Digital Media CONTENTdm: Digital Media Management SystemManagement System

A multifunction software suite used to build and manage multimedia collections and make them available on the Web Import, index, store, and manage digital objects,

as well as search and display them Can store many digital media types including

images, text documents, compound objects, audio and video files

Designed for library and cultural heritage collections

25

CONTENTdm: Digital Media CONTENTdm: Digital Media Management SystemManagement System

Built on digital library standards XML, Dublin Core, VRA Core 3.0 (Visual Resources

Association ) Supports OAI (Open Archives Initiative) Protocol for

Metadata Harvesting

Supports single and multiple collections Individual metadata for each collection Capability to search across collections

Offers batch loading to WorldCat starting with version 3.5 Version 3.7 released in August, 2004

26

Descriptive Metadata Descriptive Metadata

Metadata to provide a description of the digital object and its intellectual content Describe objects in a consistent, standardized

way Enhance access - provide means of searching in

multiple ways Facilitate access to the original source

Controlled Vocabulary Controlled Vocabulary

Use controlled vocabulary to ensure consistent metadata entry

Define a list of valid terms for a field Create controlled vocabulary lists as text files

and import them to CONTENTdm Add cross-reference terms to the lists

the Nordic Metadata Project at http://www.lub.lu.se/metadata/DC_creator.html

36

Maintaining the CollectionMaintaining the Collection

Document the digitization process Compile documentation during the project Write final project report

Promote the collection Issue press releases and announcements Schedule presentations and workshops

Update the collection with feedback from users Enable OAI support on the server and register the

collection with a OAI harvesting service, e.g. OAIster http://www.oaister.org/o/oaister/

Update the collection with time according to new digital technologies and standards

37

PreservationPreservation

Two sets of master TIFF files are stored at UWM Libraries The archival master files can be used to create other

types of digital derivatives or high-quality prints Document the digitization process to ensure a

long-term retention of the archival files Follow guidelines included in the OCLC/RLG report “A

Metadata Framework to Support the Preservation of Digital Objects”

Follow the NISO standard “Technical Metadata for Digital Still Images” to record the metadata on the item level

38

Preservation MetadataPreservation Metadata

Metadata for identifying master files and maintaining them over time

Collection level metadata: compression, resolution, and bit depth

Metadata on item level: digital file id, file size, dimensions in pixels, scan date, and master file location

41

Lessons Lessons

Focus on the users and outcomes Apply standards to build a robust and sustainable

collection Avoid the hidden costs of internal development of

applications Select a commercial digital image delivery system if

programming expertise is not available Include time for indexing and metadata creation in

your project plan Metadata creation can take up to 2/3 of the project time

Address the issue of master file preservation
