Hi,
I have installed the isbn egg, and have successfully used
valid-isbn? and isbn->alist. However, I can't seem to get
normalize-isbn, even with strings for which valid-isbn?
return #t:
#;1> (use isbn openlibrary)
...
#;2> (define isbn "8573261854")
#;3> (valid-isbn? isbn)
=> #t
#;4> (isbn->alist isbn '(title authors))
=> ((title . "Memórias do Subsolo") (authors ("Fiodor Dostoievski")))
#;5> (normalize-isbn isbn)
Error: Not a valid length for an isbn: "8573261854"
Call history:

I thought I'd have to convert it to ISBN-13 first, but that didn't
help:
#;6> (isbn10->isbn13 isbn)
=> "978-8-57326-185-1"
#;7> (normalize-isbn "978-8-57326-185-1")
Error: Not a valid length for an isbn: "978-8-57326-185-1"
...
Is it a bug or did I miss something?
Also, is this really supposed to work?
#;2> (valid-isbn? "blah blah 8573261854")
#t
It's actually nice if I'm trying to detect the ISBN within
a line (text converted from PDF, for example), but then
I can't use it as a valid ISBN as input to the other
procedures:
#3;> (isbn->alist "978-0262011532")
=> ((isbn . "978-0262011532") (title . "Structure and interpretation of
computer programs") (authors ("Harold Abelson and Gerald Jay Sussman, with
Julie Sussman; foreword by Alan J. Perlis")) (publisher "Cambridge, Mass. : MIT
Press ; c1996."))
#4;> (isbn->alist "blah blah 978-0262011532")
=> ((isbn . "blah blah 978-0262011532"))
Thanks!
J.
