Authority Express File Names

In order to provide rapid turn-around of files submitted for AEX processing,
you must name the file that you send according to the following instructions.

1. The base filename

The base filename consists of:

a. The library's 5-character account identifier as assigned by LTI followed by:

b. Up to 10 characters to help you identify the file.

The additional characters must be alpha characters, numerals, or the
underline ("_") or hyphen ("-") character. No other special
characters or spaces are permitted in the base filename.

You may use upper-case and/or lower-case characters in the base filename BUT
Authority Express will change them all to upper-case in the output file names.

The base filename MUST be unique. Do not submit the same filename more than
once -- Authority Express will not process a file with a duplicate filename.

For example, if your account identifier is "LIBID", then a
proper base filename would be LIBID001 or LIBID2000-01-01.

2. The filename extension

a. When you submit a bibliographic file for AEX
processing, the filename extension must be ".IN".

For example, LIBID001.IN

b. When you submit a text file to add authority records, the filename
extension must be ".ARADD".

For example, LIBID001.ARADD

c. When you submit a text file to delete authority records, the filename
extension must be ".ARDEL".

For example, LIBID001.ARDEL


Names of Files Returned by Authority Express

After AEX processing, a number of files are returned to you.

Each file's name will begin with the same base filename as the file you
submitted. The filename extension indicates the content of the file as described
below.

MARC Record Files

LIBIDxxx.OUT -- finished file of MARC bib records

The bib records you submitted with all authority control changes
inserted.

LIBIDxxx.LCN -- new name-related LC authority records

The LC authority records that linked to the name, title, and series
headings and which have not previously been sent to your library.

LIBIDxxx.LCS -- new subject-related LC authority records

The LC authority records that linked to the subject headings and which
have not previously been sent to your library.

LIBIDxxx.LCY -- new series-related LC authority records

The LC authority records that linked to the series headings and which
have not previously been sent to your library.

NOTE: This separate file of series-related records is created only if you
explicitly requested it. Otherwise, the series-related records are included
in the ".LCN" file.

LIBIDxxx.LCG -- new form/genre LC authority records

The LC authority records that linked to the form/genre headings and which
have not previously been sent to your library.

LIBIDxxx.LCM -- new MeSH authority records

The MeSH authority records that linked to the MeSH headings and which
have not previously been sent to your library.

LIBIDxxx.LCJ -- new LC Annotated Card (Children's) authority records

The LC authority records for Annotated Card headings (001 field begins
with "sj") that linked to the records and which have not
previously been sent to your library.

ASCII Text Files

LIBIDxxx.ACF -- authority control statistics report

Lists the headings by tag, detailing the link results obtained.

LIBIDxxx.ULH -- unlinked headings list

A list of all headings in which subfield "a" did not link to an
LC or LTI authority record.

LIBIDxxx-nfichg.ACR -- changes to non-filing indicators.

List shows title fields in which non-filing
indicators were changed as part of processing. Report is also available
to libraries not using LTI's non-filing indicator fix and may be used by
local staff to make needed edits to the fields.

LIBIDxxx.ARAOUT -- number of authority records added

Reports the number of authority records added
to the library's authority record file at LTI.

LIBIDxxx.ARDOUT -- number of authority records deleted

Reports the number of authority records deleted from the library's authority record file at LTI.

If There's a Problem With Your File...

LIBIDxxx.ERR -- error information list

There was a problem with the file you submitted: either
the MARC structure contained errors, or the filename repeats a previously
processed filename. This ASCII text file reports the nature of the error(s).

LIBIDxxx.BAD -- bad MARC record file

If any of the bib records you submitted contained errors in its MARC
structure (see .ERR above), this file will contain the bad records. These
records were removed from the file and no further processing was performed. If
a .BAD file is generated, all associated files should be removed from the
server. The file to be processed should be re-sent with errors fixed or
erroneous records removed.

Optional ASCII Text Files:

LIBIDxxx-880chg.ACR - Changes to controlled heading where 880 field is
present

List shows controlled headings with $6 that were changed during
processing. The report may be used by library staff to make needed edits
to the corresponding 880 fields.

LIBIDxxx-880err.ACR - Errors in linkage between controlled heading and
880 fields.

List shows records where the linkage between romanized with $6 and
corresponding 880 fields is faulty. The report may be used by library
staff to make needed edits to the corresponding 880 fields.
