MAY 2019 UPDATE
This month
the Library of Congress is launching a redesigned online
ordering system for the Duplicate Materials Exchange Program
(DMEP). The new system offers several new features for our
exchange partners. These new features include:
- The capability of refining search results
- A new wish list offers details about which
associate account added an item to the wish list
- A progress bar to show the steps of placing an
order
- More detailed information in the order history
- The ability to store more than one email address in
your profile
- Security enhancements
GENERAL INFORMATION
The Library of Congress
exchanges library materials with approximately 4,000 partners
around the world through its Duplicate Materials Exchange
Program. The web-based version of the program, called Web
DMEP, allows partners to select exchange materials online.
Web DMEP provides many improvements over the
traditional process of distributing printed lists of
available materials and soliciting selections from hundreds
of partners at the same time. Improvements include:
- Partners receive the items they select. As items
are selected, they become unavailable to other partners.
- There is no need to send exchange list reply forms
to DMEP.
- Partners have access to an entire database of
available titles in all subject areas.
- A variety of searching methods are available to
allow partners to locate books of interest.
- The traditional DMEP subject lists are also
accessible online.
- Partners receive immediate feedback on their
requests, including an e-mail confirmation when an order is
placed and a later e-mail message when the order has
actually been packed and shipped.
- Orders ship soon after they are placed, instead of
being batched with hundreds of other orders as they were in
the traditional process.
- Partner quotas are updated online as orders are
submitted.
NOTE: DMEP continues to produce printed
lists and to distribute them to our partners who are unable
to use the new web-based system. These printed lists contain
a different, but comparable, selection of books.
The following apply to both Web DMEP and to
the continuing program of printed exchange lists.
- Only books and selected single editions of
reference works published as serials are made available on
exchange.
- The books made available on exchange are considered
to be of enduring research value. Certain classes of books,
such as textbooks and books on popular topics such as
cooking, are excluded.
- There are twelve different subject categories based
on combinations of the LC subject classification schedule,
as listed below. Users of the Web DMEP service can browse
titles in these categories or search for books across all
categories.
- general works (A), education (L) & library
science (Z)
- philosophy, psychology & religion (B)
- history (C, D, E, F), military & naval science (U
& V)
- science & computers (G-GE & Q)
- anthropology, folklore, recreation (GF-GV)
- economics (H-HJ)
- sociology (HM-HX)
- political science (J) & law (K)
- music (M) & art (N)
- literature, criticism, linguistics, journalism,
cinema (P)
- medicine (R)
- agriculture (S) & technology (T)
- A key component of DMEP is to inform partners in
advance of the number of books they may receive (subject to
their availability) each year. A partner's annual quota is
based on the Library of Congress receipts from the partner
during the previous fiscal year. Monographs and other
format materials are compensated on a piece per piece
basis. Annual serial subscriptions receive two quota
points.
The Library's exchange
partners are encouraged to communicate by email or fax
whenever possible, as DMEP experiences delays in the delivery
of regular mail. The email address is: [email protected] and
the fax number is: 1-202-707-9440. Feel free to contact us
with your questions or comments.
