This is a fantastic site that “makes it easier to find teaching and learning resources from the federal government.  More than 1,500 federally supported teaching and learning resources are included from dozens of federal agencies. New sites are added regularly.” 

The site is extremely well-organized and easy to search.  Choose a topic from the subject list and find great information about everything ranging from  scientists, countries of the world, history, and jazz to ethnic studies and literature.

Great Books Index

http://books.mirror.org/gb.titles.html

This site offers links to online English translations of  many of the great books of the world.

Sensible Units

www.sensibleunits.com

You must excuse me, but I love this site.  If you are anything like me, and have trouble visualizing measurements and sizes, then this site might be helpful.  When you type in known units, the site provides comparable objects.  For example, 48 grams=1 golf ball or 1500 square feet=10 parking spaces.

Interactives

www.learner.org/interactives/

I first discovered this site when looking at their interactive periodic table, which is quite nice.  Learner.org offers interactive tools and tutorials on a number of topics that will be of interest to students of all ages.  Math, science, history and art topics are included.

Free Online Tech Books

Thanks to Christina Barnes (Business/Sciences) for passing along this site!

www.freetechbooks.com

This site provides links to several hundred online books that are provided by publishers and authors at no cost to the user.  Subjects covered include: Computer Science, Programming, Mathematics, and Operating Systems.

Making “cents” of it all

www.xe.net

This is a useful site for a variety of people.  Those who travel a lot can quickly find out the conversion of their American dollars into foreign currencies.  I personally like it because I read a lot of British fiction (Brit-lit) so I can find out, for instance, how much the “Shopoholic” truly did spend in American dollars instead of English pounds.  Talk about getting more bang for your buck!

All Things Converted

With the tap of a few computer keys you can now convert any quantity from one measurement system to another.  The online conversion calculator is a massive interactive website, which enables the user to make conversions in weight, mass, temperature, speed, area, volume, and so on. You can figure out how many pinches of sugar it takes to make a cupfull. Or you can figure out the area of your backyard in centimeters. No matter what it is you wish to convert, it can be done here. How many stilb does it take to make a footlambert? How old are you in dog years? If you have 150 Botswanan Pula, how many American dollars will that fetch you? These and just about any other variety of conversion-related question can be answered by using the numerous calculators found at:

Happy converting!

Kevin Dixon (Staff Development) found this site on LibrarianInBlack:

www.purplemath.com

“Purplemath offers a wealth of help with algebra problems of all types, as well as links to other sites with free tutorials, quizzes, solving software (ooh, wish they had that while I was young), and other useful mathy things.”

Mathwords

From Damone Virgilio (Staff Development):

www.mathwords.com

“It is a really useful site with definitions and examples of nearly any mathematical concept you can imagine–from basic arithmetic to quantum physics.  I discovered it while resolving a debate about imaginary numbers.  I won the bet, so it has already become invaluable to me!”
