Greetings,
I have a small book collection (~150) that I thought would be neat to
catalog by the Library of Congress catalog numbers. I have found a
LOC search form that will allow me to input the ISBN, and it will
return the information I want:
[code]http://www.loc.gov/cgi-bin/zgate?ACTION=INIT&FORM_HOST_PORT=/prod/www/data/z3950/locils2.html,z3950.loc.gov,7090[/code]
I have the list of book ISBNs in a text file, so scripting this
should be quite easy. The problem is I can't figure out how to submit
the form from the command line. I figured wget would be the best way,
but everything I try results in downloading a single line that reads
"Your form didn't include an ACTION!" So I thought I would turn to
here for help. The test ISBN I am using is for The Linux Cookbook:
1886411484, QA76.76.O63S788 2001.
And a related side question. From my reading, I've learned that the
Z39.50 protocol is used to query databases, usually library related.
Is anyone aware of an ISBN database table that can be downloaded by
the user, preferably in a format that can be imported into MySQL or
PostgreSQL?
Thanks, Craig
The url you give is for the form. If you enter an ISBN number it will
do the search.
What you need to do is capture the http header sent when you click
"submit query" then replace the test ISBN number with whatever number
you want to search. Wireshark can do this. Simply look for the query
packet(s).
The fields you need are shown in the page source:
<FORM METHOD="POST"ACTION="/cgi-bin/zgate">
<INPUT NAME="ACTION"VALUE="SEARCH"TYPE="HIDDEN">
<INPUT NAME="DBNAME"VALUE="VOYAGER"TYPE="HIDDEN">

Use of this form results in a search of the LC Voyager database (approximately
14 million records). This database contains records in all bibliographic
formats (i.e., books, serials, music, maps, manuscripts, computer files, and
visual materials), and includes the retrospective, unedited older bibliographic
records known as the PreMARC File. LC name and subject authority records
cannot be searched.
<INPUT NAME="SESSION_ID"VALUE="5923056"TYPE="HIDDEN">
</FORM>
You need to construct the query using those fields with those values, with
TERM_1 containing the ISBN number.
From the error you are getting, it seems like your query either didn't include
the SEARCH action or the header wasn't understood.
