Introduction
------------

This archive is a collection of laboratory spectra compiled by members
of the CRISM Science Team for comparison with spectra acquired by the
CRISM instrument on the Mars Reconnaissance Orbiter.

Please note that the Spectral Library is currently in review and may be
updated and improved as a result of the review.


Volume Contents
---------------

The volume contains the following directories:

CATALOG - All files in the Catalog directory are ASCII text documentation
of the data, instruments, laboratories, personnel and references relevant
to this archive. They are also used to load the PDS Catalog so that the
information is available for online searching. The file VOLDESC.CAT in the
root directory is a catalog file that describes the archive volume. This
is also an ASCII text file.

DATA - Spectral Library products are found in the Data directory grouped in
subdirectories by data provider. The Spectral Library data are all ASCII text 
files with attached PDS labels.

DOCUMENT - The Document directory contains the CRISM Spectral Library 
Software Interface Specification in Adobe PDF and HTML formats. A single PDS
label describes both versions. 

INDEX - The Index directory contains the file INDEX.TAB, a table with one 
row for each Spectral Library file in the Data directory. The table lists the 
path and file name, the product ID, the product creation time, producer, and 
other information about the product. The file INDEX.LBL is a PDS label that
describes the table. All files in this directory are ASCII text.

EXTRAS - The Extras directory contains chemical and other analyses for some
of the Spectral Library products. Files in the Extras directory are of various 
formats and do not all have PDS labels. The contents of this directory are 
not required to comply with PDS standards, and are provided as useful but 
not critical ancillary information.
