Open Library is an online project intended to create "one web page for every book ever published". Created by Aaron Swartz, [3] [4] Brewster Kahle, [5] Alexis Rossi, [6] Anand Chitipothu, [6] and Rebecca Hargrave Malamud, [6] Open Library is a project of the Internet Archive, a nonprofit organization.
In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.
The three vectors spanning a parallelepiped have triple product equal to its volume. (However, beware that the direction of the arrows in this diagram are incorrect.) In exterior algebra and geometric algebra the exterior product of two vectors is a bivector, while the exterior product of three vectors is a trivector. A bivector is an oriented ...

The cross product or vector product is a binary operation on two vectors in three-dimensional space and is denoted by the symbol ×. The cross product A × B of the vectors A and B is a vector that is perpendicular to both and therefore normal to the plane containing them.
ipl2 - merger of the collections of resources from the Internet Public Library (IPL) and the Librarians' Internet Index (LII) websites, hosted by Drexel University College of Information Science and Technology; Refdesk - free and family-friendly web site that indexes and reviews quality, credible, and current web-based resources
There are now a plethora of e-book sites that place children's picture books, along with LeapFrog-like sound effects and word pronunciation, completely online-often for free. Some will actually read an entire story aloud. These "virtual libraries have done a lot to both preserve books and make them more available.
