The University of Pennsylvania maintains a list of more than 10,000 online books:

The New General Catalog of Old Books and Authors aims to ``catalog all deceased authors, and all authors of books published before 1964, including their full name(s), date of death, date of birth, pseudonyms, sex and nationality (for non-EU citizens who died after c1920), and their books published before 1964.''. It indexes more than 24,000 books at

Cartoons and comic strips

Computer Science bibliography archives

There is a huge (1,100,000+ entries) database of bibliographic information in computer science and related subjects at Universität Karlsruhe:

There is another archive, original devoted to DataBase systems and Logic Programming (DBLP), but now being expanded to other areas of computer science, changing the meaning of DBLP to Digital Bibliography & Library Project, at Universität Trier: The archive has about ten mirrors around the world for faster access at your site, and offers search-by-author, and lists of conferences and journals covered.

Computer Science literature

Computer Science technical reports

Computer third party resellers

Computer connecters

Computer vendors


Internet services

Electronic journals

Non-electronic journals

On-line bibliographies of some of these journals are available in BibTeX format. Most of the professional organizations listed below have pointers to their journals and other publications, so they are not duplicated here.

Electronic magazines and newsletters

Government Web sites

Hubble Heritage Project

Images and projects for the Hubble Space Telescope, including new pictures of Saturn, are available at and at the Space Telescope Science Institute Web site,

ISO, ANSI, FIPS, NISO, and Open Group standards (draft, final, and commentary)

The International Organizations for Standardization (ISO) has its own Web site at in Engish and also in French. ISO maintains an index to recent ISO Standards at

ISO maintains a list of freely available (usually because they have been superceded by newer ones) standards at

The National Resource for Global Standards provides an online index to various international standards: visit

U.S. Federal Information Processing Standards (FIPS) are available at with indexes by category, keyword, and publication number. Newer FIPS standards are freely available in full text form via links from that site.

In most cases, ISO Standards are expensive copyrighted documents, sold for profit, and not available in machine-readable form. There are, however, some exceptions in the list below. In rare cases, they may be reproduced in textbooks (e.g., Herbert Schildt, The annotated ANSI C standard: American National Standard for Programming Languages C: ANSI/ISO 9899-1990, Osborne/McGraw-Hill, 1990, ISBN 0-07-881952-0, and Jeanne C. Adams et al., Fortran 95 Handbook: Complete ISO/ANSI Reference, MIT Press, 1997, ISBN 0-262-51096-0.) or in draft form in journals (e.g., ACM SIGNUM and ACM Fortran Forum).

For information about (human) languages on the Internet, visit the Internet Society Babel Web site. The ISO character set standards are highly relevant in this area.
