Please use the proper format for your bibliographies and citations.  Check the BibHelpers in the Reference Room or the English Department Style Guide (pdf format) here.

We have some books on this topic in the library; do a keyword search for "simple machines" or the specific simple machine you are looking for.  Please check our resources in the Reference Room & Non-Fiction areas, especially the Science area, 530-590, Applied Sciences, 600, as well as The Way Things Work (David Macaulay - R600 Mac) and the Eureka Encyclopedia (Mary Reilly McCall & Bridget Travers - R608 Eur).  Finally, you can always find information in the school encyclopedias and in our online resources, including Britannica 2000, and Worldbook 2000.

When looking for information on the net, please check Yahoo! first, using the same search terms above.  This sites organization and "hand-picked" links will be your best resource.

As always, if you need any help, please see me...Mr. Rompf
