Hi Bryan,
Thanks for the information. I also downloaded Lintadditions. Right now, I'm
trying to figure out what I want to do. I'm new to object-oriented programming
in Perl, so it's a learning experience for me. What I think I need to do is
create my own module for checks specific to ebook records, like checking that
all records have an 856 field with 2nd indicator 0 or an electronic resource
007, among other things. I need to think about it more and play around with the
different modules more.
Thanks,
Shelley

I'm playing around with using MARC::Errorchecks for reviewing ebook
records we get from vendors. I want to make some modifications to
the module, but I find that if I do so in a similar manner
described in the tutorial for customizing MARC::Lint, by making a
subclass of the module, it doesn't work. Is this not possible with
Errorchecks?
Indeed, MARC::Errorchecks was not written in the object-oriented
style that MARC::Lint uses. Skimming through the code just now (I've
not worked with it as regularly as I might like to be able to keep
it fresh in my memory), I believe it is essentially a collection of
subs with a wrapper sub to call each check--check_all_subs() calls
each of the checking subroutines and returns the arrayref of any
errors found. When I wrote it I was still early in learning Perl
(and while I've gotten better since then, lack of recent practice
working with it hasn't necessarily improved my knowledge of the
language), so I'm sure it's not the most optimized code possible.
check_all_subs() and the POD comments could serve as an index to
each of the checks, with the SYNOPSIS showing examples of how to
call the individual checks.
That said, if you have ideas for additions or changes, or other
questions, I welcome hearing about them, either to add to the base
module or to help with creating a related module of your own. I do
know that I need to get working on the changes required for RDA
records, but haven't really even started looking into the challenges
those will pose (though that will likely result in a new module or
more devoted just to RDA, and will also likely require
changes/subclasses to MARC::Lint and MARC::Lintadditions).
Also of note, I have a newer version I've just uploaded to CPAN [1]
with the following changes (in addition to those listed below, I
plan on removing MARC::Lint::CodeData from the Errorchecks
distribution and then requiring MARC::Lint, which includes CodeData
(to hopefully resolve issues with installing both module packages at
the same time due to this file):
Version 1.16: Updated May 16-Nov. 14, 2011. Released 7-17-2012.
-Removed MARC::Lint::CodeData and require MARC::Lint
-Turned off check_fieldlength($record) in check_all_subs()
-Turned off checking of floating hyphens in 520 fields in
findfloatinghyphens($record)
-Updated validate008 subs (and 006) related to 008/24-27 (Books and
Continuing Resources) for MARC Update no. 10, Oct. 2009 and Update
no. 11, 2010; no. 12, Oct. 2010; and no. 13, Sept. 2011.
-Updated %ldrbytes with leader/18 'c' and redefinition of 'i' per
MARC Update no. 12, Oct. 2010.
Version 1.15: Updated June 24-August 16, 2009. Released , 2009.
-Updated checks related to 300 to better account for electronic
resources.
-Revised wording in validate008($field008, $mattype, $biblvl)
language code (008/35-37) for ' '/zxx.
-Updated validate008 subs (and 006) related to 008/24-27 (Books and
Continuing Resources) for MARC Update no. 9, Oct. 2008.
-Updated validate008 sub (and 006) for Books byte 33, Literary form,
invalidating code 'c' and referring it to 008/24-27 value 'c' .
-Updated video007vs300vs538($record) to allow Blu-ray in 538 and 's'
in 07/04.
[1] While the CPAN indexer works on that:
http://www.cpan.org/authors/id/E/EI/EIJABB/MARC-Errorchecks-1.16.tar.gz
, I've also posted the file to my website:
http://home.comcast.net/~eijabb/bryanmodules/MARC-Errorchecks-1.16.tar.gz,
with text versions of each file visible in:
http://home.comcast.net/~eijabb/bryanmodules/MARC-Errorchecks-1.16

Finally, I meant to mention it on this list earlier, but I've posted
a new version of MARC::Lint, 1.45, to CPAN [2], with the current
development version (as of now, same as CPAN's version), in
SourceForge's Git repository [3]. Updates to that module include:
- Updated Lint::DATA section with Update No. 10 (Oct. 2009) through
Update No. 14 (Apr. 2012)
- Updated _check_article with the exceptions: 'A ', 'L is '
