Stock management
Modern integrated library systems collect information about the
performance of stock in terms of issues, making it possible to
ascertain whether the bookstock is achieving predetermined
levels of issues during its lifetime. (See also performance
measures)
-
Information can be
collated relating to particular branches or particular subjects
enabling a detailed picture of the use made by the public of
particular books in particular places, removing much of the
subjectivity which used to be an unavoidable feature of stock
purchase and management.
-
Stock which has
been heavily issued or which is not issuing enough can be
identified and appropriate action taken. It must be remembered
that libraries have a stewardship role regarding items of
special value, local interest or rarity, and such items will
need to be identified in the system to avoid discarding them.
To ensure that
stock is issued as much as possible it may be necessary to
rotate or exchange stock in branches.
-
It is better to
identify stock as suitable for circulation when it is ordered,
though it can of course be so identified at any stage.
-
It may be advisable
to identify part of the book-fund as being for the purchase of
circulating stock.
-
Libraries may be
paired or a circulation rota may be drawn up, such that only one
copy of a particular book/library item is bought for that rota
so that it can later be exchanged. Normally six months is
considered long enough for a book to stay in a library before it
is moved on.
-
Reports are sent to
a branch advising them of stock to be taken from the shelf and
moved on. Any stock on loan is re-routed on return.
Commercially
produced integrated library systems now commonly include a stock
management module to enable books to be identified as
circulating stock and to facilitate what can at times be a
troublesome process. For example, the Galaxy circulation control
software has a stock rotation module as does the Dynix system.
Automated Storage and Retrieval Systems
(ASRS)
Users request an item from the on-line catalogue and it is
searched for by a robot in the automated storage and brought to
the library for the user; the whole process is automatic and
should be very quick. These systems are akin to the machinery
used by supermarkets and warehouses to store produce and
retrieve it automatically. RFID may well make them a realistic
possibility. They have the following advantages:
-
Because staff and
public do not need access to the store, the temperature,
humidity and pressure can be adjusted to suit books and
documents rather than people.
-
Lighting, wall
coverings and false ceilings are unnecessary.
-
ASRS can return the
books to the bins in which they are stored in a fraction of the
time normally taken by human shelvers.
-
The system records
the use made of individual volumes which is useful for
stock-management; little used volumes may be discarded and
well-used volumes can be brought back to the open access part of
the library.
Such a system would
clearly only be useful to a library service with a large number
of books to store, but some public library services may be big
enough to justify the expense. For a discussion of the merits of
such a system (see www.ala.org/acrl/kirsch.pdf). The applicability
of ASRS to the storage of archives does not need to be
underlined.
Interlibrary loans and document supply
Interlibrary loan, or the loan or supply of books or other
items, is a scheme libraries use to gain access to materials
they do not hold. Most libraries will participate in such
schemes which may be organised on a local, regional, national or
international basis. ISO 10160 provides specifications relating
to ILL, requests, request forwarding, forwarding and
notification, shipment, conditional reply, cancellation etc. It
has been amended to support electronic data delivery.
Commercially available integrated library systems often include
a module designed to deal with interlibrary loans for example
Galaxy by DS Ltd and Talis.
Serials control
Serials check-in can be speeded up. Systems now available
handle such things as prediction pattern handling, claiming and
currency conversion. Orders chasers are generated automatically
and counts of items received or outstanding are available
online.
Commercial ILS vendors are tending to base serials control
systems on the MARC21 Holdings Format. Libraries must cultivate
an understanding of MARC holdings coupled with an appreciation
of how the format serves their needs in anticipating next
expected issue, claiming, and contributions to OPACs and union
lists.
Community
Information (See also diverse cultural content)
ILS systems should support community information systems
designed to be accessible to the public, perhaps by means of a
website.
-
They may provide
access to staff and public alike; useful to those library
services running a telephone based enquiry service.
-
They may have
search facilities including browsing indexes, free-text and
searches by subject and by locality.
-
Letters and emails
generated automatically to people requesting updates to
information in the database.
-
Out of date
information should expire automatically.
Z39.50 searching
on OPACS
The Z39.50 protocol gives searchers the ability to query any
catalogue or bibliographic file without needing to understand
the different search interfaces provided by different software
suppliers. This addition is needed by libraries which are
members of co-operating groups. (See resource description)
Management
Information Systems
It is now possible for ILS systems to include management
information modules which generate reports based on the data
recorded by the system. The management information may be
supplied alongside the main server and the main database is
“mirrored” on the MIS database enabling complex searches to be
carried out in real time without affecting response times.
Different user permissions can normally be defined. (See also
performance measures.)
The impact of new technologies on traditional ILS modules
The newest technology in this field is RFID - Radio Frequency
Identification. Its adaptation for use by libraries is very
recent. An RFID system comprises 3 essential components:
-
A tag, or a label
placed inside each item. It contains an etched antenna and a
tiny chip which contains bibliographic information and a unique
number which identifies each item.
-
An antenna which
generates a radio frequency field.
-
A reader which
powers the antenna. The information stored on the chip is
decoded by the reader and sent to the p/c or server.
Some tags can be
reprogrammed, some cannot. Some tags cannot be
used as security tags, some can. Tags have varying
amounts of memory. The more the memory the greater the cost.
Purchasers should ascertain how much memory they need.
Barcode-based
systems currently in use cause delay by requiring the correct
line-of-sight positioning of a barcode in relation to an optical
barcode-scanner. They do not themselves store any information
about the item but must be related to a database.
RFID tags have the following advantages:
-
The tags store
about 90 bits of information about each item.
-
Some have memories
which can be updated.
-
They can be read
through book-covers, while in motion, several at a time and
while they are some inches away from the antenna.
-
RFID systems should
be compatible with the computerised catalogues now in use but
this is by no means certain and checks should be carried out.
In addition,
readers’ tickets can be smart cards which would also record
information abut them, which could be automatically updated as
they passed antennae, books would be discharged from their
tickets or charged to them, fines and reservation charges
calculated, and the information would be on their cards not on
the database as at present. This could have uses in the
personalisation of services.
The kind of function performed by RFID more quickly and
efficiently than formerly includes:
