103 This script exports MARC authority, bibliographic, and serial holdings
104 records from an Evergreen database.
106 Input to this script can consist of a list of record IDs, with one record ID
107 per line, corresponding to the record ID in the Evergreen database table of
108 your requested record type.
110 Alternately, passing the --all option will attempt to export all records of
111 the specified type from the Evergreen database. The --all option starts at
112 record ID 1 and increments the ID by 1 until the largest ID in the database
113 is retrieved. This may not be very efficient for databases with large gaps
114 in their ID sequences.
117 --help or -h This screen.
118 --config or -c Configuration file [@sysconfdir@/opensrf_core.xml]
119 --format or -f Output format (USMARC, UNIMARC, XML, BRE, ARE) [USMARC]
120 --encoding or -e Output encoding (UTF-8, ISO-8859-?, MARC8) [MARC8]
121 --xml-idl or -x Location of the IDL XML
122 --timeout Remains for backward compatibility. No longer used.
123 --type or -t Record type (BIBLIO, AUTHORITY) [BIBLIO]
124 --all or -a Export all records; ignores input list
125 --replace_001 Replace the 001 field value with the record ID
126 --store Use the given storage backend to connect to the database.
127 Choices are (reporter, cstore, storage) [reporter]
128 --since Export records modified since a certain date and time.
130 Additional options for type = 'BIBLIO':
131 --items or -i Include items (holdings) in the output
132 --money Currency symbol to use in item price field [\$]
133 --mfhd Export serial MFHD records for associated bib records
134 Not compatible with --format=BRE
135 --location or -l MARC Location Code for holdings from
136 http://www.loc.gov/marc/organizations/orgshome.html
137 --library Export the bibliographic records that have attached
138 holdings for the listed library or libraries as

144 IDs contained in a file named "list_of_ids":
