These are the most frequent additions SLC customers request to DLC
and LAC records:

008/07-10 Beginning date for serial
  CONSER practice is to use latest coverage date of first issue, e.g.,
  an almanac for 2004-2005 published 2002 would have 2005, rather than
  the beginning publication year 2002.  Customers want publication year.

040 missing $b$c

Field 040 says $a who catalogued; $b in which language (LAC records
only); $c who made it machine readable; and $d who finished the
record. Today originals are usually done in one operation online, but
lie and use 040 $aCaBNvSL$cCaBNvSL$dCaBNvSL.  If changing a LAC French
record to English access points (Canadian federal government publications),
remove 090$bfre.  Repeat the 040$acode in $c if lacking; and add
$dCaBNvSL.  MARC record checking software expects to find at least
subfields $a and $c.  

050 LCC call number final Cutter
  DLC records lack a Cutter after some class numbers subdivided by year.
  Customers want a Cutter, even if after year.

  LAC records may have "*" in 055 for a topic or geographic Cutter   
  which would be different in English and French Canada.  If there is
  no complete call number, complete it and move it to 050 4 with other 
  LCC if not FC, KF (not US law); leave those in 055.

246 Distinctive subtitle
  This is the SLC's most frequent addition.  An art exhibition catalogue
  with 245 10 $aJoe Blow :$bpaintings at sunrise, gets 246 30
  $aPaintings at sunrise, since that could be mistaken for the title.
  The same applies to a distinctive title following words such as
  "Introduction to".
     
  We add 246 3  $a for any title by which an item is normally called
  whether on the item or not,  e.g., Moonlight sonata, White paper
  on taxation, Patriot Act.

260$a Place of publication jurisdiction qualifier DLC and LAC records
  have jurisdiction transcribed if present, but usually not supplied for
  lesser known cities if lacking from the title page, contrary to AACR2
  1.4C3. SLC always supplies jurisdiction except for New York, using
  AACR2 abbreviations as opposed to postal codes, and with the addition
  of "Que." for "Quebec".

260$c Beginning date for serials
  CONSER practice is to omit date if first issue is not in hand.  SLC
  customers want beginning date if known, and estimated if not, as per
  AACR2 1.4F7.

300 Collation for remote electronic resources SLC adds a 300 smd to
  narrow the meaning of the gmd [electronic resources], e.g., 300  $a1
  website :$bsd., animated col. ill., 300 $a1 electronic document (x,
  100 p. : graphs). :$bpdf file.

490 Series as on item.
    Beginning June 1, 2006, the US Library of Congress is coding all
    series as 490 0.

    It has been SLC policy since January of 1979 to have no 490 0 in
    bibliographic records.  (Some but not all SLC customers index 490
    in their series and/or title indexes, making access uneven between
    customers.)  When you encounter a 490 0, and it contains no subject
    word, or a responsible corporate body or person, e.g., "Penguin 
    books", change the 490 0 to a 500 quoted pseudo series statement.

    If the 490 0 transcribed series statement contains a subject word,
    e.g., "Studies in chemistry", change the 490 0 to 490 1, and enter
    the series in 830  with 2nd filing indicator 0-4.  If the series title
    is generic, e.g., "Report" or "Works", and has been established in 
    either the LC or LAC authority files, add the name of the responsible 
    ody or person in curves. 

    Provide ";$v" issue number or year as relevant.  Include ISSN in $x 
    if available.

    All series changed from 490 0 will be under title.  SLC will not
    create 800/810/811.  for current LC derived or original cataloguing.
    Those headings in legacy and Amicus records will be left unchanged, 
    but 830 for the 8XX$t will be added for the benefit of customers who 
    do not index 8XX$t.

520 Summary.  Our clients tell us that inclusion of summaries increases
    use due to keyword searching.  But if quoting with "--<source>", we
    attempt to screen out publisher's "puff" adjectives substitutomg
    "...", and just include the parts which actually tell you something
    about the item.  When cataloguing an electroic resource from a pdf,
    there is of a summary which can be cut and pasted.

6XX Subject headings
  Often a subject heading is added, e.g., a 610 10 for an Act which is the
  subject of the work.

  Add a 630  4 for the title by which a work discussed is commonly known,
  e.g., Moonlight sonata,  White paper on taxation, Patriot Act.
