The FARs (or Federal Aviation Regulations) are the regulations imposed by the FAA on aviation within the United States.

Many questions make reference to FAR 23, or FAR 91 etc. What are each of these? Where can one lookup the text?

    $\begingroup$ I don't think this qualifies so much as "asking for resources" - I know a lot of people who get halfway through ground school before realizing that the FAR/AIM is (a) 2 different books glued together, and (b) really just a paper copy of the Code of Federal Regulations that they can look up on their iPrecious for free :) $\endgroup$ – voretaq7 Dec 21 '13 at 20:53

In the US the "Federal Aviation Regulations" (FARs) is shorthand for referring to Title 14 of the Code of Federal Regulations.

You can browse all sections of FARs at ECFR.Gov.

FAR 23, for example, covers airworthiness standards. § 23.25 regulates weight limits.

    $\begingroup$ In addition to the eCFR version of the FARs (which is kept current with changes in near-real-time as new legislation passes) you can also get bound copies of the FARs (usually with a copy of the AIM tacked on to the back) at pretty much any pilot shop. With the abundance of excellent electronic versions the paper is mostly useful as a 1.5-lb ballast for weight & balance :-) $\endgroup$ – voretaq7 Dec 21 '13 at 20:56

FARs on the web

There are several sites on the web, but my favorite is the FAA's own Regulatory and Guidance Library at http://rgl.faa.gov/. If you click the Code of Federal Regulations link on their main page, you can look at current and historical regulations as well as preamble information, links to the dockets, NPRM's, and more. Just click on "By Part" under the "Current CFR" section, and you can browse through each section. If you then scroll down, you will find the two that you asked about:




Click the arrow next to each part and it will show links to the full text of each regulation.
