Wikipedia:WikiProject Mathematics/Reference resources

From Wikipedia, the free encyclopedia

This page collects helpful resources — Web sites, books, journals, and so on — to assist in writing good mathematics articles. To follow the scientific citation guidelines adopted by WikiProject Mathematics, every article should cite high quality sources where readers can learn more about the topic. In the spirit of Wikipedia, most sources listed here can be freely viewed and downloaded without charge and without access restrictions, thus they are particularly convenient for both editors and readers alike. As well, some tools are listed to help find and format citation data.

[edit] Source formats and viewing options

Many valuable references in mathematics are beginning to migrate from inaccessible libraries to scans available on the web. This includes both classical publications and recent ones. The most common document formats are:

  1. HTML: Hypertext markup language, the standard web browsing format
  2. PDF: Portable document format, the Adobe Acrobat format
  3. PS: PostScript, Adobe's format for printing
  4. DjVu: a compact format for scanned documents
  5. DVI: Device independent format, produced by TeX

Scans of historical works are significantly more compact in DjVu as compared to PDF, and often the text can be searched. Readers for this popular format can be downloaded and used at no cost. Adobe's PS (and PDF) format can be imaged for viewing using a Ghostscript implementation (with Ghostview), which also can be downloaded and used freely. On Linux systems, the Evince viewer can handle DVI as well as other formats, and DVI viewers are also available freely available from LizardTech for Microsoft Windows and Mac OS systems.

There are also some convenient tools to find data and produce formatted citations:

[edit] ISBN

An ISBN makes a reference to a book unambiguous, and can help readers to locate a reference. Suppose, for example, you want to cite a book by Hartman entitled Ordinary Differential Equations. If you use Google to search for [Hartman "Ordinary Differential Equations" ISBN] (note the quotes around the title and the explicit request for the search term ISBN), you quickly discover that the second edition, reissued in soft cover in 2002, has ISBN 0898715105. This handy online tool will convert an ISBN-10 into a correctly hyphenated ISBN-13, for this example ISBN 978-0-89871-510-1.

One caution is that a book will have a different ISBN for hard, soft, reprints by different publishers, and different editions. Sometimes it is acceptable, even a good idea, to list the most recent edition (and soft if available), but sometimes not. For example, material covered in an older edition may be dropped in a newer one; and page numbers and other location information may change. Consider what one Amazon.com reviewer of Mac Lane and Birkhoff's Algebra, 3/e, ISBN 978-0-8218-1646-2, says about this book in three editions: "[I]t also contained unusual topics such as multilinear algebra and affine and projective spaces, but no Galois theory. The second edition has gained a chapter on Galois theory, but has lost the part on affine and projective spaces. The third edition is the best! It has recovered the part which was lost in the second edition, and had its exposition considerably polished." Going back to the Hartman example, this means that if the article refers to, say, Chapter VII: The Poincaré-Bendixson Theory, of

  • Hartman, Philip (1964), Ordinary Differential Equations, Wiley 

then it may be a mistake to change the citation to

which is an unabridged but corrected (soft) reprint of the (hard) second edition

The only way to be sure is to see what the article depends on and compare both texts.

[edit] Verifing references

Finding potential sources for references can often be done by a simple Google search, as described above, or if you only wish to consider academic sources, Google scholar. Only cite a (reliable) source after you have verified that the source actually supports the statements in the article. Although not optimally convenient, Google book search allows you to search book texts, and can sometimes be used for such verification if no online version or library copy is available. Also Amazon.com allows reading fragments of some books online.
