The

Dewey

Decimal
...
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.

Not

all

In

the

...
- 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.
...
- Less
...
- than
...
- CONSER-level
...
- records
...
- in

- OCLC
...
- are
...
- eligible
...
- for

...
- upgrade:
...
- LC

- call

- numbers
...
- and
...
- LC

- AACR2/ISBD.
...
- Open
...
- serial
...
- records
...
- (CONSER
...
- or
...
- non-CONSER)
...
- can

- be

- the

- In

...
- whether
...
- to

- upgrade
...
- a

- record
...
- or

- the

...
- discretion.
...
- Whenever

- All

- the

- DDC

...
- are

- assigned

- full

...
- Cutters
...
- must
...
- be
...
- checked
...

- in

- MARC
...
- fields
...
- 090
...
- or
...
- 050:14)
...
- may
...
- be
...
- accepted
...
- without
...
- re-analysis;
...
- however,
...
- again:
...
- all
...
- Cutters
...
- must
...
- be
...
- checked
...
- against
...
- MIT's
...

...
- list.
...
- The
...
- final
...
- step
...
- of
...
- cataloging
...
- in
...
- OCLC
...
- involves adding to the record two local fields:
Wiki Markup {{910 RECON\[cataloger's intials\]\[YYMMDD\]}
...
} (?) This field goes into the local bib., so that we know who cataloged the serial and when.Wiki Markup {{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.
