Electronics magazines are a rich mine of useful projects, general information and tutorial articles.  The library holds back copies and most have extensive web sites on which you can download material and order CDs of past issues, indexes etc.

Data sheets are usually available via the internet.

Data sheet archive search engine
alldatasheet web site.

The library has a useful page giving electronic reference material that you can search for research material.  INSPEC run by the IEE and IEEE is a useful starting point.
If you are using PICs then try my PIC resource page.
If you are using a LCD alphanumeric display (e.g. on a Millennium board or similar) then:
bullet Try this web site for background information
bullet How to connect a PIC to a 16 2-line LCD display
bullet A PowerPoint presentation on using CCS C with your display (read this!) (also )
The EE Internet Info Sites has a wealth of links to educational institutions, companies, individuals and on-line magazines.
Stuck for circuit ideas? Try the University of Washington's Electronic Engineering Archive site. This contains circuits, models, data sheets, textfiles and microprocessor information.
Another site with the same type of material is over at the University of Alberta in Canada.
The main site for Motorola is here. From this opening page you can get to the various services provided; for data sheets, resources, software tools etc.
For those interested in the PIC microcontrollers then go to the Microchip site.
The student's guidance page for the eeshop at the University of Nebraska-Lincon lists many sources to download CAD and simulation packages. Particularily useful are the links to the shareware version of Pads, the schematic and PCB design packages and the full manuals. Other links provide the evaluation version of OrCAD's PSPICE.
If you are interfacing to the serial or parallel port of your PC then go to here to get documents on how to do this. I have mirrored some of these .pdf and .htm documents as they were on April 20th, 1998 but they could have been updated since. They are:
Interfacing the Serial/RS232 port (40-page ).
Interfacing the standard Parallel port (SPP) (17-page ).
Interfacing the enhanced Parallel port (EPP) (6-page ).
Interfacing the extended capabilities Parallel port (ECP) (12-page ).
Concise LCD data sheet (1-page ).
Using the PC's interrupts (18-page ).
Analog sampling via the Serial/RS232 port (.htm).
Connecting a LCD module to the RS-232 port (.htm).

In addition there are lots of postscript and .htm documents and links to other relevant sites. Worth a visit.

Another site with useful data on things serial is at bandbeurologo.GIF (2082 bytes)
Texas Instrument's site at is a rich source of applications notes and data sheets covering design with digital logic (for example choosing bypass capacitors), linear electronics (for example a tutorial on operation amplifier specifications), dsp, charge-coupled devices, RF communication electronics... The document on logic design is located at this server (as for the other examples above) for your convenience.
Answers to your Logic or dsp questions try the KnowledgeBase from Texas Instruments.
The Edinburgh Engineering Virtual Library (EEVL) is available at . EEVL is the UK gateway to quality engineering information on the Internet, maintaining a searchable directory of reviews and links to quality engineering Web sites. EEVL also provides targeted engineering search engines, indexes to print literature and other specialist information services.
Searching for applications information? The EE Design Center community page can be electronically searched for data sheets and application libraries.
The home page for harris.gif (4018 bytes) is here. Harris (now Intersil) do a vast range of digital, hybrid and analog components.
How to write your project dissertation. Dozens of links from the University of Newcastle.
Tomi Engdahl's Electronic Info Page is an Alladin's cave of electronic links.  Try the Basics page first.   Everything from Abbreviations to Smith charts through Twisted pair cable to Various formulas. 
If you are using a Liquid-Crystal Display then here is the Hitachi HD44780 data sheet. Hitachi passed on their semiconductor business to Renesas in 2003, and you can get details on their web site.
A few data sheets stored locally.
