Haik, I think you are trying to make one 856 do more than it was intended to do.
The Library of Congress MARC guidelines say this about $u subfields: "*Subfield $u (URI) repeatability.* Subfield $u may be repeated only if both a URN and a URL or more than one URN are recorded. Field 856 is repeated if more than one URL needs to be recorded. Some institutions may wish to record a persistent name (URN) as well as a resolvable HTTP URL in field 856." <http://www.loc.gov/marc/856guide.html#subfield_$u> So, unless you are using a different form of MARC (and I realize that this is an international list, so this may be the case) you should not put more than one URL per 856 instance. You can have a second $u field only if there is a URN in that field. Since most URNs are not "clickable", it makes sense that OPACs generally display only the first $u, which contains the URL. In short, multiple URLs would require multiple 856 fields. The usual construction of an 856 field that links to the resource itself is: =856 40$3[materials specified - optional]$u[url]$y[link text -optional]$z[public note - optional] In practice, most records have either a $y or a $z, though you can have both of those in one 856. Both $y and $z show up in Koha as link text. The only required subfield in an 856 is the $u. You need not have any other text, and if you don't put in a $y or $z, Koha will supply a default link text. An example of a typical 856 would be: =856 40$3Ebrary$uhttp://ebrary.com/somebook$yAn online ebook. Click here for access. It sounds as if you may have constructed your 856 fields this way: =85640$[URL1]$y[Link text 1]$uURL2$y[Link text 2]$uURL3$y[Link text 3] You need to edit these to change them into multiple 856 fields, each with only one $u and one $y: =856 40$u[URL1]$y[Link text1] =856 40$u[URL2]$y[Link text2] etc. Hope this helps. -- Stacy Pober Information Alchemist Manhattan College Library Riverdale, NY 10471 [email protected] > Date: Sun, 23 Dec 2012 21:59:41 -0800 (PST) > From: Haik Zargaryan <[email protected]> > To: "[email protected]" <[email protected]> > Subject: [Koha] cloning 856 $u > Message-ID: > <[email protected]> > Content-Type: text/plain; charset=iso-8859-1 > > Dear friends, > > We want to attach several URLs to the MARC record.
