Cite NumPy in BibTex How to cite NumPy in BibTex?
The Scipy citing page recommends:

Travis E, Oliphant. A guide to NumPy, USA: Trelgol Publishing, (2006).

Is it correct to use:
@Misc{numpy,
  author =    {Travis Oliphant},
  title =     {{NumPy}: A guide to {NumPy}},
  year =      {2006--},
  howpublished = {USA: Trelgol Publishing},
  url = &quot;http://www.numpy.org/&quot;,
  note = {[Online; accessed &lt;today&gt;]}
 }

Or should I cite just SciPy?
Research Gate
On Research Gate, the citation suggested is:
@book{book,
author = {Oliphant, Travis},
year = {2006},
month = {01},
pages = {},
title = {Guide to NumPy}
}

Or cite as a book?
Looks right to me. That's how they ask to be cited, and it seems reasonable. Indeed, this discussion also agrees that citing the user manual is the right choice.
