C99
The international standard which defines the C programming language is available from ISO, and participating countries via their national body's publishing arrangement(s), many of which are available via the web for easy purchasing. The current revision is ISO/IEC 9899:1999 -- also called C99 -- for which there are 3 corrigenda. Each participating country adopts the standard into their own standards system (some use the same document number) and in some cases changes are made to the document, though the technical content should (and really must) remain the same.
The working group (WG14) makes some of the drafts, the rationale by which they made their decisions (The Rationale) and issues raised against the standard (Defect Reports) available for free from their web site, see Web_resources#Secondary_materials for the links. You can obtain the standard for free, in effect because they have made the combination of the base and all 3 corrrigenda available as a draft, document N1256.
The British Standards Institute (BSI) has published The Standard, TC1 and The Rationale in a bound book, see Books#References for the link.

C89 / C90 / C95
The older standards -- ANSI X3.159-1989 (aka C89), ISO/IEC 9899:1990 (aka C90), ISO/IEC 9899:1990/AMD 1:1995 (aka AMD1 or C95) -- are no longer available from official sources, so your best source is a printed book. C89 and C90 are identical except for the frontmatter and section numbering.
Rumor has it that BSI has C90 -- their web site says they do -- but so far nobody has confirmed being able to purchase and receive it.
SAI-Global, the exclusive publisher for Standards Australia, has AS 3955-1991 (C90) available:
- AUD 157.50 - PDF: http://www.saiglobal.com/shop/script/Order.asp?Media=PDF&DocN=stds000005269
- AUD 175.00 - hard copy (printed): http://www.saiglobal.com/shop/script/Order.asp?Media=HC&DocN=stds000005269
USA ANSI/INCITS still lists the following PDF of C90 as available for download:
AMD1 can be ordered from IHS (née Global Engineering Documents):
- enormous product page url hidden for USD 56 for PDF and USD 70 for hard copy (printed).
Many standards can be ordered from good technical booksellers, such as opamp.
Note: Implementations which conform with C89/C90 are more widely available than those which conform with any later revision(s).
