1. Terminology has changed a lot for author, titles, volumes into works, expressions, manifestations.
2. MAJOR RDA CHANGES BY MARC FIELD
RDA change:Compilers of works by more than one author are again main entry, as they were prior to AACR2.
RDA change: Entry under first author, regardless of number.
RDA change: Treaties are entered under the first country mentioned, regardless of number or alphabetical order, or in the case of a
treaty between one country and a group of countries, enter under the one country.
RDA change: From older records remove "$pO.T." and "$pN.T." from
between "Bible" and $p name of the individual books. For the Old
and New Testaments, spell out O.T. and N.T.
RDA change: Use square brackets only for information not found in
the item, regardless of source within the item. Leave brackets
in older records.
RDA change: Record all authors given in prime source in 245 /$c.
In older records, the title is the main entry in this case, i.e., no 100.)
RDA change: use first author mentioned as 100.
RDA change: "[sic]" or bracketed additional letters no longer used
after typos. Create 246 with corrected spellings.
RDA change: For compilations, use the RDA option of supplying a title
in brackets, rather than using the title of the first work as title
proper. (This allows us to continue creating only one bibliographic
record per physical item, a requirement for many of our clients.)
RDA change: When/if ILS have made the change, enter media terms in
336-338 (qv), omitting 245$h. While 245$h is used, continue to use
RDA change: Transcribe all authors, regardless of number. But, in
the case of a compilation, transcribe statements of responsibility
after titles in 505.
Abandonment of the Rules Of Three removes the need for "[et al.]" or
RDA change: Transcribe rather than abbreviate, e.g., 250 $a Second edition.
SLC will not adopt RDA transcription in full, nor omitting jurisdiction
if absent. SLC will transcribe or supply jurisdiction using AACR2
abbreviations. Supply missing information in a note does not work
in brief displays.
SLC will continue to use ISBD Latin abbreviations rather than English
phrases, because of our international customer base.
SLC will Continue to use AACR2 abbreviations, due to different
spellings in different languages.
336-338 Cf. 245$h
RDA change once ILS can accept:
336 Media type
electronic (do not use computer)
337 Carrier type
Use one or more of the terms listed below, as appropriate.
1) Audio carriers
2) Electronic carriers
computer chip cartridge
computer disc cartridge
computer tape cartridge
computer tape cassette
computer tape reel
3) Microform carriers
4) Microscopic carriers
5) Projected image carriers
slide (Use for photographic slides only)
5) Stereographic carriers
6) Unmediated carriers
7) Video carriers
If none of the terms listed above apply supply appropriate term
RDA change: Tracing all authors as opposed to only 2nd and 3rd.
RDA change: A compiler of the works of more than one person is
now 100 main entry.
RDA change: For a treaty entered under title, change the first
710 (first jurisdiction mentioned in the treaty title) to 110, and
the 245 1st indicator to 1 if 0. Change any 130 to 730.
November 2015 Changes:
Laws, etc. - - - Eliminate "Laws, etc." as a conventional collective title. The remaining use of this term in RDA will be for references to various types of laws.
Treaties, etc. - - - This was also eliminated.
Before you start reading about RDA keep these in mind:
Functional Requirements for Bibliographic Records
This is the theoretical framework under which RDA was constructed. It describes the relationships between and among the different elements in a bibliographic record.

MARC is a carrier of data. The tags and subfields were designed so that a machine could manipulate the data. Many people think that MARC isn't a good carrier for newer data about data (metadata). Many catalogers think that MARC doesn't do RDA justice and if we had a better carrier, we'd appreciate RDA more.
International Standard for Bibliographic Description
You probably learned about ISBD in library school. RDA uses ISBD punctuation in most places.
Resource Description and Access
These are the new rules for describing things that will replace AACR2
For summary or explanations of what and why see the JSC brochure http://www.rda-jsc.org/docs/rdabrochureJanuary2010.pdf

In 2013 RDA = Resource Description and Access = new cataloging rules will be implemented by the Library of Congress and the library world. Here is some information given at the AALL 2012 annual meeting about RDA.
RDA records in OCLC Connexion were shown as well as the new macros and drop-down menus for original catalogers. Also shown were step-by-step instructions on how to view RDA records in the Library of Congress catalog at http://catalog.loc.gov
With RDA records being added every day, simply clicking on "KEYWORD SEARCH," selecting "EXPERT" and then typing "k040 rda" allows you to view RDA records in full or MARC format. Also you can add "and k955 xg?" to your search terms to limit your results to law-related records.
Websites to check out:
There are many websites that contain information about RDA and how to use it. Go to
Library of Congress websites
AALL Technical Services SIS [logon required]
In OCLC you can search for these records using a variety of search strategies that you would normally use but limiting them to dx:rda
dx is a new index that searches the 040 $e
You can also limit your search by formats: eg. dx:rda and mt:ser (for serial RDA records)
or by date dx:rda/2011
or dx:rda/2011/dlc [searches for LC rda records]
