Wikipedia:WikiProject Mathematics/Reference resources
Main page | Discussion | Content | Assessment | Participants | Resources |
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.
Editors can request access to specific articles or books or information on a specific topic at Wikipedia:WikiProject Resource Exchange/Resource Request.
Source formats and viewing options
[edit]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:
- HTML: Hypertext markup language, the standard web browsing format
- PDF: Portable document format, the Adobe Acrobat format
- PS: PostScript, Adobe's format for printing
- DjVu: a compact format for scanned documents
- 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.

Document identifiers
[edit]ISBN
[edit]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
- Hartman, Philip (2002), Ordinary Differential Equations (2nd ed.), SIAM, ISBN 978-0-89871-510-1
which is an unabridged but corrected (soft) reprint of the (hard) second edition
- Hartman, Philip (1982), Ordinary Differential Equations (2nd ed.), Birkhäuser, ISBN 978-0-8176-3068-3
The only way to be sure is to see what the article depends on and compare both texts.
Verifying references
[edit]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.
Guidelines for selected websites
[edit]This started as a translation from Russian of Matematicheskaya entsiklopediya and was acquired by Springer, a publishing house with a long and respected history in mathematics. It has since been updated and expanded, and is now freely available on the web. As of 2011, the site has been converted to a wiki so new material can be added; Springer's board of editors will maintain quality.
- Link to website
- Referencing template
{{SpringerEOM|title=|id=|last=|first=}}
- Reliability
- Should be regarded as a highly reliable source.
- Notability
- Nearly every article should have a corresponding article in Wikipedia, though some titles will need to be changed to conform to Wikipedia naming guidelines. There are a few survey type articles where the material should be covered more completely in several Wikipedia articles.
Originally published as a website, then collected as a book (The CRC Concise Encyclopedia of Mathematics) and taken down from the web, then acquired by Wolfram Research who put on the web again as MathWorld where it continues to be updated and expanded.
- Link to website (alphabetical index)
- Referencing template
{{MathWorld|title=|urlname=|author=}}
- Reliability
- Usually regarded as a mediocre source, particularly with regard to terminology. Most articles have a list of references which, if published in reliable venues, may be better sources than MathWorld itself.
- Notability
- Nearly all material should be regarded as encyclopedic. However MathWorld has a reputation for creating neologisms so article names should be only be used if notability can be established independently; otherwise, it's better to add the material to an existing article. Also, MathWorld has a tendency to have separate articles for different aspects of a single subject. For example it has 17 separate articles for different Elementary cellular automata. In such cases it's better to gather all the aspects together into a single Wikipedia article.
This started as a project to take over for MathWorld when that site was temporarily taken down due to a lawsuit. It is edited by users, much like Wikipedia, but in some ways it's very different.
- Link to website (subject index)
- Template
{{PlanetMath|urlname=|title=}}
- Reliability
- Though PlanetMath uses a different verifiability model than Wikipedia, it does not meet Wikipedia's criteria for a "reliable source". So additional sources should be found when possible if citing PlanetMath.
- Notability
- Again, because PlanetMath is user edited it should not be used as a criterion for notability. However, the corresponding PlanetMath article often makes a valuable addition to an External links section.
Hosted by the University of St Andrews, this is a useful resource for historical and biographical information. The site is organized by several indexes: Biographies, History Topics, Additional material, and Famous curves.

{{MacTutor|class=|id=|title=}}
- Reliability
- Should be regarded as a reliable source.
- Notability
- Most articles in the Biographies index should have a corresponding article in Wikipedia. Some of the articles in the other indexes are more essay-like in style and the material may not be encyclopedic.
An educational site with an articles on a variety of mathematical subjects, geared toward students. More a collection of essays and demonstrations than an encyclopedia, but it can be a valuable resource.
- Link to website
- Reliability
- Though not a published source, the recognition the site has received from publications such as Scientific American, the Encyclopædia Britannica, and Science Magazine means it should probably be regarded as reliable.
- Notability
- Since the articles on the site are more in the nature of essays, some of the material is not encyclopedic.
A vast, searchable collection of sequences and tables from a variety of mathematical areas. This started as a reference book but has grown in size and scope due to the power of the internet.
- Link to website
- Link template
{{OEIS|id=}}
- Reliability
- Material is submitted by users but is validated an editorial board before being added to the site. A sequence appearing in a Wikipedia article should be accompanied by its OEIS link.
- Notability
- There are too many entries in the OEIS for them all to be considered encyclopedic in the Wikipedia sense, so the presence of a sequence in the OEIS should not be used as direct evidence of notability. However, the REFERENCES section of an entry may list sources that can be used to establish the notability of a sequence.
