Exhibit 99(a)(7)


This announcement is neither an offer to purchase nor a solicitation of an offer
to sell Shares (as defined below). The Offer (as defined below) is made solely
by the Offer to Purchase, dated November 21, 2001, and the related Letter of
Transmittal and any amendments or supplements thereto, and is being made to all
holders of Shares (except for Parent (as defined below) and its subsidiaries).
The Offer is not being made to (nor will tenders be accepted from or on behalf
of) holders of Shares in any jurisdiction in which the making of the Offer or
the acceptance thereof would not be in compliance with the laws of such
jurisdiction. In any jurisdiction where the securities, blue sky or other laws
require the Offer to be made by a licensed broker or dealer, the Offer will be
deemed to be made on behalf of Purchaser (as defined below) by one or more
registered brokers or dealers that are licensed under the laws of such
jurisdiction.

Notice of Offer to Purchase for Cash
All Outstanding Shares of Common Stock
of
Liquent, Inc.
(formerly known as ESPS, Inc.)
at
$2.27 Net Per Share
by
Fluid Acquisition Corp.,
a wholly owned subsidiary of
Information Holdings Inc.

Fluid Acquisition Corp., a Delaware corporation ("Purchaser") and a wholly owned
subsidiary of Information Holdings Inc., a Delaware corporation ("Parent"), is
offering to purchase all outstanding shares of common stock, par value $.001 per
share (the "Shares"), of Liquent, Inc., a Delaware corporation (the "Company"),
at $2.27 per Share, net to the seller in cash, without interest, upon the terms
and subject to the conditions set forth in the Offer to Purchase, dated November
21, 2001, and in the related Letter of Transmittal (which, together with any
amendments or supplements thereto, together constitute the "Offer"). Tendering
stockholders will not be obligated to pay brokerage fees or commissions or,
except as set forth in Instruction 6 of the Letter of Transmittal, transfer
taxes on the purchase of Shares by Purchaser pursuant to the Offer. The purpose
of the Offer is to acquire for cash as many outstanding Shares as possible as a
first step in acquiring the entire equity interest in the Company. Following the
consummation of the Offer, Purchaser intends to effect the Merger (as defined
below).

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
TIME, ON WEDNESDAY, DECEMBER 19, 2001, UNLESS THE OFFER IS EXTENDED.

The Offer is conditioned upon, among other things, there being validly tendered
and not withdrawn prior to the expiration of the Offer that number of Shares
that, together with any Shares then beneficially owned by Parent or Purchaser or
any of their respective subsidiaries, represents at least a majority of the
issued and outstanding Shares on a fully diluted basis. Certain other conditions
to the Offer are described in Section 13 of the Offer to Purchase. The Offer is
not conditioned upon Parent and Purchaser obtaining financing. Certain
stockholders of the Company who beneficially own approximately 49% of the
outstanding Shares have agreed, among other things, to tender their Shares
pursuant to the Offer.

The Offer is being made pursuant to the Agreement and Plan of Merger (the
"Merger Agreement"), dated as of November 13, 2001, among the Company, Parent
and Purchaser, pursuant to which, after completion of the Offer and the
satisfaction or waiver of certain conditions, Purchaser will be merged with and
into the Company and the Company will be the surviving corporation (the
"Merger") and each issued and outstanding Share (other than Shares held in the
treasury of the Company, Shares owned by Parent or any direct or indirect wholly
owned subsidiary of Parent or the Company and Shares which are held by other
stockholders who properly exercise dissenters' rights, if any) will, by virtue
of the Merger and without any action on the part of the holder thereof, be
canceled and converted into the right to receive an amount in cash, without
interest, equal to the per Share price paid pursuant to the Offer. The Merger
Agreement is more fully described in the Offer to Purchase.

The Board of Directors of the Company has unanimously approved the Merger
Agreement and the transactions contemplated thereby, including the Offer and the
Merger, and determined that the Merger Agreement and the transactions
contemplated thereby are fair to and in the best interests of the Company and
the Company's stockholders, and unanimously recommends that the Company's
stockholders accept the Offer and tender their Shares pursuant to the Offer.

For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not properly
withdrawn if and when Purchaser gives oral or written notice to EquiServe Trust
Company, NA (the "Depositary") of its acceptance for payment of such Shares
pursuant to the Offer. Upon the terms and subject to the conditions of the
Offer, payment for Shares accepted for payment pursuant to the Offer will be
made by deposit of the purchase price therefor with the Depositary, which will
act as agent for the tendering stockholders for the purpose of receiving
payments from Purchaser and transmitting such payments to the tendering
stockholders. Under no circumstances will interest be paid on the purchase price
for Shares, regardless of any extension of the Offer or any delay in making such
payment.

In all cases, payment for Shares tendered and accepted for payment pursuant to
the Offer will be made only after timely receipt by the Depositary of (a)
certificates for such Shares or confirmation of the book-entry transfer of such
Shares into the Depositary's account at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures set forth in Section
3 of the Offer to Purchase, (b) a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees
(or, in the case of a book-entry transfer, an Agent's Message (as defined in
Section 3 of the Offer to Purchase) in lieu of the Letter of Transmittal) and
(c) any other documents required by the Letter of Transmittal.

Tenders of Shares made pursuant to the Offer are irrevocable, except that
Shares tendered pursuant to the Offer may be withdrawn at any time prior to
the Expiration Date as defined below and, unless theretofore accepted for
payment by Purchaser pursuant to the Offer, may also be withdrawn at any time
after January 19, 2002, except as provided with respect to any subsequent
offering period. The term "Expiration Date" means 12:00 midnight, New York
City time, on Wednesday, December 19, 2001, unless Purchaser, in its sole
discretion (subject to the terms of the Merger Agreement), shall have
extended the period of time during which the Offer is open, in which event
the term "Expiration Date" shall mean the latest time and date on which the
Offer, as so extended by Purchaser, shall expire. Subject to the terms of the
Merger Agreement and the applicable rules and regulations of the Securities
and Exchange Commission, Purchaser expressly reserves the right (but will not
be obligated), in its sole discretion, at any time or from time to time, to
extend the period of time during which the Offer is open by giving oral or
written notice of such extension to the Depositary. Any such extension will
be followed as promptly as practicable by public announcement thereof, such
announcement to be issued no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled Expiration Date. During any
such extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the right of a tendering stockholder to
withdraw such stockholder's Shares.

For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Depositary at one of its
addresses set forth on the back cover of the Offer to Purchase. Any such
notice of withdrawal must specify the name of the person having tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and (if
certificates for such Shares have been tendered) the names in which the
certificate(s) evidencing the Shares to be withdrawn are registered, if
different from that of the person who tendered such Shares. The signature(s)
on the notice of withdrawal must be guaranteed by an Eligible Institution (as
defined in Section 3 of the Offer to Purchase), unless such Shares have been
tendered for the account of any Eligible Institution. If Shares have been
tendered pursuant to the procedures for book-entry transfer as set forth in
Section 3 of the Offer to Purchase, any notice of withdrawal must specify the
name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Shares and otherwise comply with the Book-Entry
Transfer Facility's procedures. If certificates for Shares to be withdrawn
have been delivered or otherwise identified to the Depositary, the name of
the registered holder and the serial numbers shown on such certificates must
also be furnished to the Depositary as aforesaid prior to the physical
release of such certificates. All questions as to the form and validity
(including time of receipt) of any notice of withdrawal will be determined by
Purchaser, in its sole discretion, which determination shall be final and
binding. None of Parent, Purchaser, the Depositary, the Information Agent
(listed below), or any other person will be under any duty to give
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give such notification. Withdrawals of
tenders of Shares may not be rescinded, and any Shares properly withdrawn
will be deemed not to have been validly tendered for purposes of the Offer.
However, withdrawn Shares may be retendered by following one of the
procedures described in Section 3 of the Offer to Purchase at any time prior
to the Expiration Date. Under the Merger Agreement and pursuant to Rule
14d-11 of the General Rules and Regulations under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), Purchaser may, subject to certain
conditions, include a subsequent offering period following the Expiration
Date. Purchaser does not currently intend to include a subsequent offering
period in the Offer, although it reserves the right to do so in its sole
discretion. Under the Exchange Act, no withdrawal rights apply to Shares
tendered during a subsequent offering period and no withdrawal rights apply
during the subsequent offering period with respect to Shares tendered in the
Offer and accepted for payment. See Section 1 of the Offer to Purchase.

The information required to be disclosed by paragraph (d)(1) of Rule 14d-6 of
the General Rules and Regulations under the Exchange Act is contained in the
Offer to Purchase and is incorporated herein by reference.

The Company has provided Purchaser with the Company's list of stockholders
and security position listings for the purpose of disseminating the Offer to
holders of Shares. The Offer to Purchase and the related Letter of
Transmittal will be mailed by Purchaser to record holders of Shares whose
names appear on the Company's stockholders list and will be furnished to
brokers, dealers, commercial banks, trust companies and similar persons whose
names, or the names of whose nominees, appear on the stockholder list or, if
applicable, who are listed as participants in a clearing agency's security
position listing for subsequent transmittal to beneficial owners of Shares.

The Offer to Purchase and the related Letter of Transmittal contain important
information which should be read carefully and in their entirety before any
decision is made with respect to the Offer.

The receipt of cash for Shares pursuant to the Offer will be a taxable
transaction for U.S. federal income tax purposes; see Section 5 of the Offer
to Purchase for additional information. Questions and requests for assistance
may be directed to the Information Agent at the address and telephone number
set forth below. Requests for additional copies of the Offer to Purchase and
the related Letter of Transmittal may be directed to the Information Agent.
Such additional copies will be furnished at Purchaser's expense. Purchaser
will not pay any fees or commissions to any broker or dealer or any other
person (other than the Information Agent) for soliciting tenders of Shares
pursuant to the Offer.
