Read does not support any book retrieval mechanism. But Get Books and
Get Internet Archive Books do. Get Books support the OPDS standard,
while Get Internet Books support a CSV format used by Internet Archive
(the IA supports OPDS as well).

It depends on the format. If the books are EPUB, considerable amount
of metadata can be easily retrieved, but for formats like DJVU, there
may be no metadata at all.
The relevant section in the OPDS specs:

I would probably prefer to stick to standard formats, so that
deployments (and if possible, individual schools) would be able to
load books into the XS easily. The workflow I have in my mind is:
1. Have a specified directory on the file system which is crawled
periodically via cron.
2. If a new file is found, metadata is extracted either from the file,
or from an external CSV file which is also found at a fixed location
(CSV so that deployments can use any spreadsheet software while adding
3. Once metadata is obtained successfully the file is added to the index
The index is then generated into OPDS catalogs, which can be queried
from any XO to the XS.
Does this sound sane ?
