I release isi-1.2.0, a converter from ISI Export Format to BibTeX Format.
It runs both on 1.8 and 1.9. You can use isi as a library, too.

ISI Web of Science (http://isiknowledge.com) provides its bibliographic
information in ISI Export Format. You can get the tagged Marked List in
Web of Science by clicking the [SAVE TO FILE] button.

Usage:
=== Installation
 # gem install isi
=== Save the marked records to an output file in Web of Science
Mark the articles in Web of Science. Then, view and save the
marked records to an output file (savedrecs.txt). I recommend to
check "Author(s)", "Title", "Source", "abstract*", "keywords",
"times cited" and "source abbreviation" as the fields to include
in the output file.
=== Here are some examples
 $ isi2bibtex savedrecs.txt
 $ isi2bibtex savedrecs1.txt savedrecs2.txt > savedrecs.bib
 $ isi2bibtex < savedrecs.txt > savedrecs.bib
 $ cat savedrecs.txt | isi2bibtex > savedrecs.bib
=== Convert ISI Export Format to HTML
 $ isi2html --help
 $ isi2html --full-name='Hideki Yukawa' --name-regexp='(H\. Yukawa|Hideki Yukawa)' savedrecs.txt >
index.html
Use isi2html to create your publication list.
