At Mathematical Reviews, we work hard to make sure that our bibliographic data are correct. \u00a0We have more than twenty\u00a0people in our Acquisitions \u00a0and Cataloging Departments who verify, verify, verify. \u00a0So that you don’t have to repeat our work, we try to make it easy for users of MathSciNet\u00ae<\/sup> to obtain proper citations. \u00a0The most popular method is to choose\u00a0BibTeX<\/a><\/strong> as the “Alternative Format”.<\/p>\n

Saving\u00a0a result as a citation<\/h3>\n

If you want to save the citation to just one item, here is an example that shows you how to do that. \u00a0Let’s say that after a search, we come across the paper by Mumford and Shah where they define the Mumford-Shah functional, which is useful\u00a0in computer vision, materials science, solid mechanics, and other areas where variational methods\u00a0are important.<\/p>\n

\"Screen<\/a><\/p>\n

In the top left, we see that we can select an alternative format. \u00a0Here are the choices:<\/p>\n

\"Screen<\/a><\/p>\n

Selecting BibTeX<\/strong> produces:<\/p>\n

@article {MR997568,\r\n    AUTHOR = {Mumford, David and Shah, Jayant},\r\n     TITLE = {Optimal approximations by piecewise smooth functions and\r\n              associated variational problems},\r\n   JOURNAL = {Comm. Pure Appl. Math.},\r\n  FJOURNAL = {Communications on Pure and Applied Mathematics},\r\n    VOLUME = {42},\r\n      YEAR = {1989},\r\n    NUMBER = {5},\r\n     PAGES = {577--685},\r\n      ISSN = {0010-3640},\r\n     CODEN = {CPAMA},\r\n   MRCLASS = {49F20 (41A30 92A27)},\r\n  MRNUMBER = {997568 (90g:49033)},\r\nMRREVIEWER = {Constantin Udri{\\c{s}}te},\r\n       DOI = {10.1002\/cpa.3160420503},\r\n       URL = {http:\/\/dx.doi.org\/10.1002\/cpa.3160420503},\r\n}\r\n<\/pre>\n
You can now copy and paste this into your .bib file. \u00a0Note that the BibTeX\u00a0key<\/span> is the MR number (MR997568). \u00a0Most people switch that to something that can be remembered more easily.<\/p>\n
\n
Saving multiple citations<\/h3>\n
Often, you may want to save a collection of citations for items on a particular theme. \u00a0For instance, if you are writing a paper about the Mumford-Shah conjecture, you may want to have citations for lots of papers related to the original. \u00a0In the top right-hand corner,<\/p>\n
\"Screen<\/a><\/p>\n
we can see that there are 343 references to the Mumford-Shah paper from reference lists and 23 references to the paper from a review (i.e., the reviewer of another paper explicitly mentions the Mumford-Shah paper). \u00a0Assuming that the instances from the reviews are a good core sample, let’s use those. \u00a0Clicking on “From Reviews” gives us the list. \u00a0My preferences are set to display only 20 items per page, so we want to click<\/p>\n
\"Screen<\/a><\/p>\n
to have all 23 on screen. \u00a0Now, at the top left we see<\/p>\n
\"Screen<\/a><\/p>\n
Clicking the box with\u00a0Reviews (HTML)<\/strong> brings up the choices:<\/p>\n
\"Screen<\/a><\/p>\n
Let’s pick BibTeX again<\/p>\n
\"Screen<\/a><\/p>\n
Now you can check the boxes for your favorites among the collection to mark them, then retrieve just this subset of citations. \u00a0Or you can pick “Retrieve First 50<\/span>” and retrieve all\u00a023 citations (since 23 \u2264\u00a050), all formatted for us in BibTeX. \u00a0Here are the first two:<\/p>\n

References from the command line<\/h3>\n
Andrew Comech<\/a>, from Texas A&M, wrote a command-line script for retrieving references in BibTeX format. \u00a0It requires a subscription to MathSciNet, but it serves the needs of those who prefer not to point and click repeatedly. \u00a0The script is bibget<\/a>, and is available from Comech’s webpage: \u00a0http:\/\/www.math.tamu.edu\/~comech\/tools\/bibget\/bibget<\/a>. \u00a0The script has an option that allows you to use an SSH tunnel, so that you can use the tool from off campus. \u00a0This can fail (for the usual unknown reasons). \u00a0As an alternative, using Comech’s example, \u00a0you can try \u00a0ssh <your host name>\u00a0bibget a=gilkey t=invariance book 1984 2>\/dev\/null<\/code><\/p>\n
Notes: This is a bash<\/code> script, so you will want to use it on a linux or unix machine (or from a terminal window on a Mac). \u00a0Or you can load a port of\u00a0bash<\/code> for Windows on your machine.\u00a0 It also uses wget<\/code> or\u00a0lynx<\/code> to reach the network, so make sure you have one of those installed. \u00a0 For you Mac users, \u00a0bibget supports\u00a0curl<\/code>, which is built into most Macs. \u00a0 Comech tells me that the script is “poorly coded’, but it does get the job done. \u00a0I have met some mathematicians who use bibget to build up a master BibTeX file, which they then use for all their papers.<\/p>\n
References without a subscription<\/h3>\n
There is a tool to verify references that works even if you do not have a subscription to MathSciNet handy. \u00a0It is called\u00a0mref<\/a>.<\/strong>\u00a0\u00a0 If you type (or copy and paste) the author+title of a paper (or author + title + some journal info, if there is no unique match), you get back our bibliographic listing\u00a0of the item, including volume number, pages, year, and the MR number. \u00a0The MR number comes with a live link to the item in MathSciNet. \u00a0For instance, the search<\/p>\n
Andrew Comech \r\nOptimal regularity of Fourier integral operators with one-sided folds.\r\nComm. Partial Differential Equations\r\n\r\n<\/pre>\n
produces<\/p>\n
Comech, Andrew. Optimal regularity of Fourier integral operators with one-sided folds. Comm. Partial Differential Equations 24 (1999), no. 7-8, 1263–1281. MR1697488 (2000m:35190)<\/a>.<\/p>\n
The mref<\/code> search can be a little fussy. \u00a0It is usually best to include information about\u00a0the author, title, and the journal. \u00a0We developed the tool\u00a0originally for authors and publishers to have a way of verifying bibliographic information in reference lists for journal articles and books they were working on.\u00a0 Having the live link to the item in MathSciNet is a feature of reference lists in AMS online publications. \u00a0Note that\u00a0mref<\/code> does not offer you the option of BibTeX format.<\/del> \u00a0Correction<\/strong>: \u00a0Yes it does! \u00a0There is a big “BibTeX” button underneath the search window. \u00a0<\/code><\/p>\n
