ETD Issue: Getting StartedUniversity of Washington
Library • Space needs • Institutional repository • Initiated
Graduate School • Policy changes• Procedural adaptations• “Golden Promise” to faculty Students• Timely online availability
ETD Issue: SOFTWARE
ETD-db: submission and management http://scholar.lib.vt.edu/ETD-db/ http://scholar.lib.vt.edu/ETD-db/developer/
IRs: institutional repositories http://repositories.tdl.org/handle/2249.1/1 http://etd.lib.fsu.edu/ http://eidr.wvu.edu/
ETD-db http://scholar.lib.vt.edu/ETD-db/
• Web pages, perl scripts interact with MySQL• Standard interface for web users, authors, graduate
school, library personnel • Enter and manage files and metadata
http://scholar.lib.vt.edu/ETD-db/developer/• Software and hardware requirements • Instructions on downloading, installing, and customizing
scripts Improvements coming: September 2006
• Timed release• Merged databases• Improved OAI
ETD-dbHardware Requirements
VT uses a dual-processor Sun Enterprise 250 with 384 Mb of RAM, running Solaris 2.7. 18Gb drive is allocated solely for the ETD collection.
Web server (e.g., UNIX-based server platform) Disk space for submissions
• VT averages 2.5 Megabytes per submission• ETD-db is not designed to span multiple drives.
Memory for web server, database server, other tasks
Software Requirements Mysql Perl and CGI, DBI, DBD, and Tie-IxHash modules Web server software, e.g., Apache Web Server
Florida State University
ETD-db• Workflow advantages for Graduate School
DigiTool (ExLibris)• Search engine
DSpace• Missing functionality• Programming personnel needed
West Virginia Universityhttp://eidr.wvu.edu/
eIDR: Electronic Institutional Document Repository• ETDs since 1998• Digital library system: collections serve
entire university community
Texas Digital Libraryhttp://repositories.tdl.org/handle/2249.1/1
More than 40 campuses, 375,000 students; over 4,000 theses and dissertations in 2004.
ETDs with MODS• XML based, web friendly, transportable, processible, configurable,
sufficiently descriptive without being too complex, extensible• Why not MARC: isn’t XML based, can’t easily be output from web
forms, requires special “cataloging” knowledge and systems to implement.
• Why not Dublin Core: insufficient specificity, doesn’t specify a syntax and is inconsistently applied, isn’t extensible.
Manakin: enables communities and collections to establish a unique look and feel that is distinct from the default installation of DSpace.
ETD Issue: ACCESSIBILITY

Built by harvesting metadata from Open Archives of electronic theses and dissertations• OCLC’s NDLTD Union Catalog
247,390 NDLTD from >60 entities (135,166 US)
Ohio Library and Information Network

ETD Issue: PRESERVATION
Preservation Strategies • Dark archives• Replication w/geographic dispersion• Verification• Format migration
6 Association of SouthEastern (US) Research Libraries Adapted LOCKSS to a private, independent network using OAI-
PMH Crawled and collected web content based on permissions Each university cached every other universities’ ETDs Audited file integrity Addressed policy issues: dark archiving, removing files, adding
programs
