Index to Hard Copy Mineral References
* These volume sets of the Handbook of Mineralogy are relatively error-free. The publisher has offered a $5.00 bounty on each error found in any of the volumes. Even with webmineral's resources, It took 3 months of searching to find enough minor errors to qualify for one free volume. Most of these errors were found in the reflectivity data when that data was added to webmineral's species pages. |
