Raw data files for elliptic curves over number fields for upload to LMFDB
Programs for bianchi modular forms (over imaginary quadratic fields)
The eclib package includes mwrank (for 2-descent on elliptic curves over Q) and modular symbol code used to create the elliptic curve database.
Data files containing the Cremona Database of all elliptic curves over Q of bounded conductor: see also http://www.lmfdb.org/EllipticCurve/Q . For a description of how most of the data here was computed, see the ANTS 7 Proceedings at http://www.math.tu-berlin.de/~kant/ants/proceedings.html . For a description of the algorithms used, see the book Algorithms for Modular Elliptic Curves, published by CUP in 1992 (second edition 1997) and available online here: http://www.warwick.ac.uk/staff/J.E.Cremona/book/fulltext/
