Andy Holt Virtual Library
Unparalleled collection of links to sites devoted to every aspect of textual scholarship and the transmission of texts.

Atlas of Early Printing
An interactive site from U Iowa Libraries.  Most valuable for its atlas that allows the user to combine overlays (such as locations of
paper mills, universities, etc) with a date range.  Good list of links. European printing history only.  

Bibliographical Society
The original UK society of book scholars.

Bibliographical Society of the University of Virginia
Fredson Bowers's pet. 55 volumes, 1948-2002, all full-text searchable.

Biblioteca de Andalusia
Consortium of Andalusian libraries. Many early works scanned in their entirety. In Spanish only.

British Library

Catholic Encyclopedia
Unabridged, full-text searchable, and available without registration.

CERL
Consortium of European Research Libraries.

Codex Gigas
A digitization of the so-called Devil's Bible, the world's largest medieval manuscript (a yard high and 165 lbs!). A well-considered
site that covers all aspects of this weird object. In English, Swedish, and Czech.   

Conservation Online (CoOL)
The first place conservators go for information. Links, journal abstracts, searchable archive of online discussions.

Directory of History of Medicine Collections
A list of links to medical libraries worldwide, compiled by the National Library of Medicine.

EEBO
Early English Books Online. Scanned copies of virtually all Wing and STC titles (not full-text searchable). Available only through
subscribing libraries.    

Einbanddatenbank
Enormous site on the history of 15th and 16th century European bookbinding. Includes searchable edition of Kyriss's otherwise
unobtainable
Verzierts gotische Einbande. In German.

Getty Conservation
Vanguard conservation research institution. Programs in all disciplines.

Google Books
Ever expanding, ever constricting.

Huntington Library

InkunabelLinks
Large site compiled and vigilantly updated by Dr. Klaus Graf of the University of Freiburg. Includes fully-searchable access to
Gesamtkatalog der Wiegendrucke,
including manuscript citations for as-yet unpublished volumes.

INKA
Consortium catalogue of incunabula in 25 German libraries. Exhaustive, with a superb search engine. In German.

ISTC
Incunabula Short Title Catalogue. A great site with an excellent search engine. Most valuable as a census of known copies, with
data conflated from every conceivable source, with the notable exception of sale and auction catalogues. Links to digitized editions.

J. R. Ritman Library
Dutch library of occult titles with a small  but significant collection of early works. Searchable collection not connected with any
union catalogues.

Koninklijke Bibliotheek  
National Library of the Netherlands. Well-designed library site in Dutch and English. Interesting and thorough section on binding
conservation, particularly parchment.

La Reliure
Large site of bookbinding links, generally in French.

Latin place names
User friendly, but not exhaustive.

Metropolitan Museum of Art
Indispensible catalogue of a vast library of art books and journals. Not an easy page to find even at the Met site. Most of the
citations do not turn up in WorldCat searches.

Ladyfriend Moggie
World's greatest writer.

National Library Catalogues
List of online or soon-to-be-online National Library catalogues. National Library in this sense meaning an institution that endeavors
to hold all of its country's publications. Many are not connected with OCLC. Not a union catalogue, but a collection of links to
individual libraries. Some catalogues are nearly impossible to access through any other site; for instance the National Libraries of
Estonia, Vietnam, Faroe Islands, Sri Lanka, and many others.

OCLC
Home of WorldCat, a union catalogue of some 56 million books in 84 countries. Accessible only through a subscribing library.
When carefully used, it is an awesome resource.

Online rare-book resources
Another prodigious work by RBMS. The site likely has virtually everything that is on my list of links, plus hundreds more. Created
by Eric Holzenberg.

Open Library
An ambitious wiki-based root-and-branch book site. From the splash page: "Imagine a library that collected all the world's
information about all the world's books and made it available for everyone to view and update. We're building that library."
Certainly worth watching. In demo stage.

Piccard's Watermarks
Carefully designed and fully searchable site in French, German, and English

The Reading Room
Blog with news and interesting links, including those to several digitized B42s.

RBMS
Rare Books and Manuscripts Section of the American Library Association. First protocol for cataloguers.

Russia, National Library of
Evolving site in English and Russian, with numerous digitized works available. The OPAC of 16th-century books is in Russian only.

SCETI
Schoenberg Center for Electronic Text and Image. Now in its 13th year, it was one of the earliest digitization projects.

STOLEN BOOKS. This section I am hoping to develop comprehensively.  Please write if you have any ideas for additions.

    ABAA.  Public. The Antiquarian Booksellers Association of America keeps this list of books stolen from ABAA members
    (unrecovered and recovered). Searchable and browsable. An excellent resource.

    Art Loss Register. Private. Probably the largest subscription site for stolen art, in operation since 1991. Books are included
    as well, though I do not know to what extent.

    LootedArt.com Public. Central Registry of Information on Looted Cultural Property, 1933-45. Searchable. A good deal of
    care has gone into the descriptions of looted objects. In most cases, direct contacts are provided for each missing object.

    ILAB. Private. International League of Antiquarian Booksellers. Site accessible only by ILAB members, though libraries may
    have access if permission is obtained. I am not an ILAB member or a librarian, so I cannot comment on the site.

    Interpol. Semi-private; dealers and collectors may order a CD-ROM (updated bimonthly) of stolen cultural property,
    including books. Only law enforcement agencies may directly access the list of some 26,000 items. That said, there are
    pictures on the site of a few recent thefts, and some recent recoveries.

    Provenanced.com Public. A site ostensibly listing stolen cultural objects, including books. An anemic, unfocused, and badly
    run site, but still a base to be covered.  

    Rare Book & Manuscript Section.  Public. The Association of College and Research Libraries maintains this list, though one
    wishes it were updated more frequently.
