[Koha] OCLC enhanced content & 856 tag

[Cab Vinton]

Some of the records we copy catalog via OCLC have URL's in 856 for
enhanced content (covers, sample text, etc.), which don't lead
anywhere.

I presume this is because of an invalid key.

Is there a work-around? Are we better off simply deleting the field &
relying on Koha's Amazon/ Google services for enhanced content?

Here's how a typical 856 would be structured:

http://firstsearch.oclc.org/WebZ/DECRead?standardNoType=1
&standardNo=0764005065
&sessionid=0
&srcdbname=worldcat
&key=72a7beb35042d2bc25d11fe85b6bb7db92925155ffefd95c11ba52379d04bad4
&ectype=MOREINFO$xOCLC EC$3More Info
