>Subject: [PATCH] Bug 10486 - Allow external Z39.50 targets to be searched from
> the OPAC
>
>This adds a new page to the OPAC that can search several Z39.50 targets
>using Pazpar2.
>
>Test plan:
>1) Apply patches.
>2) Update database.
>3) Add one or more Z39.50 targets, using the Administration -> External
>   targets screen. Note that not all targets support keyword search, but
>   here are some that do:
>     * Library of Congress: lx2.loc.gov, 210, LCDB, none, none, MARC21, UTF-8
>     * BNF2: z3950.bnf.fr, 2211, TOUT, Z3950, Z3950_BNF, UNIMARC, UTF-8
>4) Perform a search on the OPAC, check to see if the "external targets"
>   notice pops up at the top.
>5) Click on the results link near that message.
>6) This should bring back results from all enabled targets, all of which
>   should be clickable to bring up a detailed view of the record.
>
>(This version fixes some typos and accidental changes.)
