[plt-scheme] online version of _The Little Schemer_?

Does anybody know where to find an online (even
fee-based) version of _The Little Schemer_?  I have a
copy at home, but would like to read it on my computer
at work and be able to copy and paste portions of the
text and code when trying out the examples in the
dialogs.

I also have the same question about the other books in
the same series:

* _The Seasoned Schemer_
* _The Reasoned Schemer_
* _A Little Java, A Few Patterns_
* _The Little MLer_
