Dirk Lewandowski and Philipp Mayr published a preprint of their contribution Exploring the Academic Invisible Web on E-LIS. Their purpose is
to provide a critical review of Bergman’s 2001 study on the Deep Web. In addition, we bring a new concept into the discussion, the Academic Invisible Web (AIW). We define the Academic Invisible Web as consisting of all databases and collections relevant to academia but not searchable by the general-purpose internet search engines. Indexing this part of the Invisible Web is central to scientific search engines. We provide an overview of approaches followed thus far.
Design/methodology/approach: Discussion of measures and calculations, estimation based on infor-metric laws. Literature review on approaches for uncovering information from the Invisible Web. Findings: Bergman’s size estimation of the Invisible Web is highly questionable. We demonstrate some major errors in the conceptual design of the Bergman paper. A new (raw) size estimation is given. Research limitations/implications: The precision of our estimation is limited due to small sample size and lack of reliable data. Practical implications: We can show that no single library alone will be able to index the Academic Invisible Web. We suggest collaboration to accomplish this task. Originality/value: Provides library managers and those interested in developing academic search en-gines with data on the size and attributes of the Academic Invisible Web.
The contribution is available in the .pdf.
