+-----------------------------------------------------------------------------
+The PostScript Type 1 implementation of the Computer Modern fonts produced by
+and previously distributed by Blue Sky Research and Y&Y, Inc. are now freely
+available for general use. This has been accomplished through the cooperation
+of a consortium of scientific publishers with Blue Sky Research and Y&Y.
+Members of this consortium include:
+
+ Elsevier Science
+ IBM Corporation
+ Society for Industrial and Applied Mathematics (SIAM)
+ Springer-Verlag
+ American Mathematical Society (AMS)
+
+In order to assure the authenticity of these fonts, copyright will be held
+by the American Mathematical Society. This is not meant to restrict in any
+way the legitimate use of the fonts, such as (but not limited to) electronic
+distribution of documents containing these fonts, inclusion of these fonts
+into other public domain or commercial font collections or computer
+applications, use of the outline data to create derivative fonts and/or
+faces, etc. However, the AMS does require that the AMS copyright notice be
+removed from any derivative versions of the fonts which have been altered in
+any way. In addition, to ensure the fidelity of TeX documents using Computer
+Modern fonts, Professor Donald Knuth, creator of the Computer Modern faces,
+has requested that any alterations which yield different font metrics be
+given a different name.

+
+Bitstream Vera Fonts Copyright

+long as "Bitstream" or "Vera" are not in the names), and full
+redistribution (so long as they are not *sold* by themselves). They
+can be be bundled, redistributed and sold with any software.
+
+The fonts are distributed under the following copyright:
