Peter Suber, "Guides to Disciplinary Guides"

Guides to Disciplinary Guides Peter Suber, Philosophy Department, Earlham College
This is an attempt to pull together the major collections of the major guides to the academic disciplines. I deliberately omit collections limited e.g. to the sciences or the humanities, although some of these are very good.

Alpha Search
From Calvin Theological Seminary. Searchable and browsable. Very large. All links annotated.
Argus Clearinghouse
"The Internet's Premier Research Library." From Argus Associates. Searchable and browsable. Very large. Each link annotated with keywords and rated on six parameters, with date of last review.
BUBL 5:15
From the University of Strathclyde in Scotland. "BUBL" formerly stood for BUlletin Board for Libraries, but is now used as a word rather an acronym. Searchable and browsable. Very large. Aims to have between 5 and 15 sites per subject area. All links are annotated and classified in the Dewey Decimal system. Supports browsing by subject and by Dewey class number.
Choice Supplement
From Martha Jones. Browsable. Dated and selective. No link annotations.
eBLAST
From Encyclopedia Britannica. Searchable and browsable. Large. All links annotated and rated. Takes site statistics from Alexa.
Galaxy
"The Professional's Guide to a World of Information." From CyberGuard Corporation. Searchable and browsable. Large. Within each discipline, it tries to do what a guide would do (often skimpily) rather than link to the best guides. No link annotations.
Infomine
"Scholarly Internet Resource Collections." From the Library of the University of California at Riverside. Searchable and browsable. Very large. Supports browsing by subject, keyword, or source title. No link annotations.
NISS Directory of Networked Resources
"Information for Education." From Britain's National Information Services and Systems. Searchable and browsable. Large. All links annotated. Supports browsing in alphabetical order by subject area, by UDC (Universal Decimal Classification) shelfmark order.
Pinakes.
"A Subject Launchpad." From Dave Bond and Roddy MacLeod. Browsable. Generally gives just one guide per field. No link annotations.
Study Web
From American Computer Resources. Searchable and browsable. Primarily for college and pre-college students. All links annotated and rated (for visual content and grade level).
UniGuide
"Academic Guide to the Internet." From Aldea Communications (formerly from InterNIC). Browsable. Stronger in the sciences than the humanities. Icons for each link replace verbal annotations.
WWW Virtual Library
Searchable and browsable. For each field, the Virtual Library provides its own guide but these usually link to the major guides in the field as well. Link annotations rare, at the discretion of the individual authors of the field guides.

I am not a completely disinterested bystander. In addition to being a teacher and scholar who uses these guides, and recommends them to students and colleagues, I am the author of guides in two areas, philosophy and knots.
