Add 4 sample RDA records from LoC

Add 4 sample RDA records from LoC

At the suggestion of Dan Scott, I went to this LoC site:

http://catalog.loc.gov/cgi-bin/Pwebrecon.cgi?DB=local&PAGE=First

I used their "expert search"

with a query of "040e rda"

then used various "search limits" of "type"

Here are the 4 record filenames, plus the available LoC permalinks to them:

RDA_record_MAP_2012_Enchanted_Circle.mrc
http://lccn.loc.gov/2013585177

RDA_record_DVD-BLUE-RAY-MOVIE_Pineapple_express.mrc
http://lccn.loc.gov/2010600022

RDA_record_PHOTO_Srid_pa_ho.mrc
http://lccn.loc.gov/2011432135

RDA_record_SERIAL_IEEE_International_conference.mrc

I originally found more than 4 RDA records, but it was pointed out that they were
using older/outdated versions of RDA. For example, the records used the 260
tag instead of using the 264 tag.
