Supplementing the Library Collection with Digital Content from Engineering Departments Karen Clay Stanford University

Questions What information is being produced in the SoE labs? (What types of publications? Digital-only or digital with online equivalent?) How accessible is this information? (Is it in the Library? At a stable URL?)

Methods Hired Engineering Graduate students to discover and input the information found Discovery methods: - browsing the lab web sites - google search of engineering web space for.pdf files - asking the labs for an inventory of their output

Refworks database Bibliographic information Document type Document format Document size URL Availability in Library

Assessment of the data Grey Literature predominates, but its primarily “standard” grey literature, not digital-only items Many URLs are not stable (at least 1% of URLs had changed or disappeared after only 5 months).

Grey Literature Predominates

Most of the online documents DO have a print equivalent

Many Documents are Not in the Library Document type:% available in Library Dissertations94% Journal articles/book chapters92 % Technical Reports57 % Conference papers15 % Other (slides, videos etc)0 % All types47%

Documents not in the Library

Collections Assessment What materials are we missing in the library?

Journals/Books not in the Library

Missing articles from 12 journal titles and 3 book titles No journal titles had more than one missing article 2/3 of the missing materials are in the Biomedical Engineering field

Dissertations not in the Library

Missing 3 non-Stanford dissertations; and 3 Master’s theses

Conference Proceedings & Technical Reports

Conference Proceedings Many of the missing conference proceedings were cited repeatedly on the web pages Center for Turbulence Research Summer Program Center for Turbulence Research Summer ProgramSome of the more commonly cited missing conference proceedings are local, small- scale conferences (for example the Center for Turbulence Research Summer Program)Center for Turbulence Research Summer Program

Conference Proceedings & Technical Reports

Technical Reports Although we are missing about 40% of the technical reports in the database, these technical reports are produced by 14 of the 66 Labs or Centers. (only about 1/5).

Conclusions There is a lot of locally produced, relevant grey literature on the web which is missing from the library. Most of this literature is still produced in “traditional” formats – formats which have a print-based equivalent This literature is currently scattered, difficult to search, and the URLs are not stable (it should be in the library!).
