Collection
...
Overview
Housed in MIT's
...
...
...
...
is
...
a
...
"hidden
...
library"
...
containing
...
thousands
...
of
...
monographs
...
and
...
serials
...
originally
...
collected
...
by
...
the
...
MIT
...
Libraries
...
and
...
classified
...
by
...
Dewey
...
Decimal
...
number.
...
The
...
collection
...
began
...
in
...
the
...
1960s
...
when
...
MIT
...
moved
...
over
...
to
...
Library
...
of
...
Congress
...
classification,
...
and
...
older
...
Dewey
...
Decimal
...
materials
...
were
...
transferred
...
out
...
of
...
the
...
divisional
...
libraries
...
into
...
a
...
central
...
location.
...
For
...
many
...
years
...
SerCat
...
has
...
been
...
involved
...
in
...
an
...
ongoing
...
project
...
to
...
catalog
...
the
...
serials
...
contained
...
in
...
this
...
collection,
...
and
...
to
...
reclassify
...
them
...
to
...
Library
...
of
...
Congress
...
call
...
numbers.
...
The
...
cataloged
...
materials
...
are
...
then
...
transferred
...
to
...
MIT's
...
Off-Campus
...
Collection.
...
Now
...
that
...
they
...
can
...
be
...
found
...
through
...
Barton,
...
patrons
...
can
...
have
...
these
...
materials
...
delivered
...
to
...
the
...
LSA
...
within
...
24
...
hours
...
from

their

request.

...
- We
...
- are
...
- currently
...
- working
...
- in
...
- the
...
- 300's.
...
- Materials
...
- are
...
- inspected
...
- on
...
- the
...
- shelves
...
- and
...
- an
...
- initial
...
- assessment
...
- as
...
- to
...
- whether
...
- they
...
- are
...
- serial
...
- in
...
- nature,
...
- and
...
- catalog-able,
...
- is
...
- made.
...
- Then,
...
- we
...
- check
...
- OCLC
...
- to
...
- determine
...
- if
...
- there
...
- is
...
- a
...
- bibliographic
...
- record
...
- for
...
- the
...
- items.
...
- If
...
- we
...
- find
...
- a
...
- record,
...
- we
...
- add
...
- our
...
- holdings
...
- to
...
- it in OCLC.
- If there is no record in OCLC, we can go ahead and create one, based on the items in hand. Encoding level (
ENCL:) should be set toI. - Less than CONSER-level records in OCLC are eligible for cataloging upgrade:
- LC call numbers and LC subject headings are added.
- Pre-ISBD / pre-AACR2 records (non-CONSER only) can be converted to AACR2/ISBD.
- Open serial records (CONSER or non-CONSER) can be closed off, if the final issue is in hand.
- Serial records (CONSER or non-CONSER) can be "backed up" if earlier or the earliest issue is in hand.
- In all cases, whether to upgrade a record or not is based on the cataloger's discretion.
- Whenever possible, non-CONSER records should be made to conform to the "CONSER standard record" practices.
- Call numbers: All serials in the DDC Recon Project are assigned full LC-call numbers. Cutters must be checked against MIT's shelf-list to avoid conflicts with previously established call numbers. LC call numbers assigned by institutions other than LC (e.g. in MARC fields 090 or 050:14) may be accepted without re-analysis; however, again: all Cutters must be checked against MIT's shelf list.
- The final step of cataloging in OCLC involves adding to the record two local fields:
910 RECON[cataloger's intials][YYMMDD]
This field goes into the local bib., so that we know who cataloged the serial and when.949 |z Serial |a x |g [summary holdings statement] This is an "expansion code", which will be converted to a proper holdings record once the bib. comes over from OCLC into Barton.
- Next day process: Records cataloged in OCLC appear in Barton the following day. "Next day" process involves updating the holdings record, creating item records and adding bar-codes, and finally housing the material (if necessary) and placing it on the "wall" in LSA. Once a month, items on the wall are removed to off-campus storage.
