Springer has open accessed a bunch of their graduate textbooks (all books older than 10 years I believe). Here is a full list http://link.springer.com/search?utm_campaign=Contact+SNS+For+More+Referrer&facet-content-type=%22Book%22&utm_source=snsanalytics&utm_medium=twitter&showAll=false&facet-series=%22136%22.
I glanced through the list and two books that might be relevant to SymPy are "Groebner bases" by Becker and Weispfenning (http://link.springer.com/book/10.1007/978-1-4612-0913-3) and "A Course in Computational Algebraic Number Theory" by Cohen (http://link.springer.com/book/10.1007/978-3-662-02945-9).
