I am sorry to say that I do not know any libraries in the UK that use
the Weine system. I am somewhat confused by your post. If you want to
physically visit a library that is using Weine I can't help. But if
you want to see the Weine system, you can join the Assoication of
Jewish Libraries which is an international organization and once you
are a member, you can download the Weine system free of charge from
the AJL website
www.jewishlibraries.org . As a non-member I think you
can still purchase the system. Purchase information is on the
website. If you just want to look at a catalog that is using Weine
online there is a list of those on the website also. Feel free to
visit my library's catalog by going to
www.jewishlibrariesdetroit.org
and following the link to Congregation B'nai Moshe Library. Hope this
helps you. And by the way let me mention that I think you mean the
Elazar system not the Salazar system named for its creator Daniel
Elazar which is the other major classification system used in Jewish
libraries (tho there are a few others out there).
