If you would like to acknowledge the LMFDB, please use a citation in the following form, alphabetized under LMFDB.

[42] The LMFDB Collaboration, The L-functions and Modular Forms Database, http://www.lmfdb.org, 2013, [Online; accessed 16 September 2013].

The BibTeX entry is:

@misc{lmfdb,
  shorthand    = {LMFDB},
  author       = {The {LMFDB Collaboration}},
  title        =  {The L-functions and Modular Forms Database},
  howpublished = {\url{http://www.lmfdb.org}},
  year         = {2013},
  note         = {[Online; accessed 16 September 2013]},
}

Then you can cite a certain object much like quoting a specific theorem from a paper. For example, you may refer to the elliptic curve with LMFDB label 11a.2 by

\cite[\href{http://www.lmfdb.org/EllipticCurve/Q/11.a2}{Elliptic Curve 11.a2}]{lmfdb}

In order to make the \url and \href commands to work, one should use the hyperref package.


To cite a specific page in the LMFDB, such as the home page of the L-function of the first rank 4 elliptic curve/$\Q$ shown in the example below, you can cite it as

[42] The LMFDB Collaboration, The L-functions and Modular Forms Database, Home page of the L-function $L(s,E)$ for the Elliptic Curve Isogeny Class 234446.a, http://www.lmfdb.org/L/EllipticCurve/Q/234446.a/, 2013 , [Online; accessed 16 September 2013].
