    "abstract": "GRTensorJ - Books is an active interface to a small part of the computer\nalgebra systems GRTensorII (for Maple) and GRTensorM (for Mathematica) with the\nspecific intent of providing students of General Relativity with an advanced\nprogrammable calculator-style tool. All standard functions associated with a\nclassical tensor approach to the subject are available thus reducing these to\n\"elementary functions\". This is not a traditional database. The database\nentries are spacetimes and calculations are done in real time. All spacetimes\nare referenced directly by equation number in ten current (and classic) texts\nin notation as close as possible to the original text. The tool is now\navailable free of charge from \\texttt{grtensor.org/teaching} .",
