                                                          Exhibit 10.6(b)

                       AMENDMENT NO. 1 TO EMPLOYMENT AGREEMENT


    This Amendment No. 1 (the "Amendment") to Employment Agreement dated
September 5, 1995 (the "Employment Agreement") by and between Infonautics,
Inc., a Pennsylvania corporation formerly known as Infonautics Corporation
(the "Corporation"), and Van Morris ("Employee") is made as of the 4th day of
November, 1996.

    WHEREAS, the Board of Directors of the Corporation (the "Board") has
previously determined that it is in the best interests of the Corporation and
its shareholders to assure that the Corporation will have the continued
dedication of the Employee and to provide the Employee with compensation and
benefits that meet the expectations of Employee and are competitive with
those of employees at comparable levels at other corporations.

    WHEREAS, to accomplish these objectives the Compensation Committee of the
Board has authorized the Corporation to enter into this Amendment.

    NOW, THEREFORE, the parties hereto intending to be legally bound, agree
as follows:

    1.   The first paragraph of Paragraph 3 of the Employment Agreement is
hereby amended and restated in its entirety to read as follows:

              "The Corporation will grant to Employee the right and
         option to purchase all or any part of 76,000 Shares on terms
         and conditions set forth in a 1995 Incentive Stock Option
         Agreement between Infonautics Corporation and Van Morris
         dated September 5, 1995, subject to amendments to provide
         for accelerated vesting upon change of control and upon
         Employee's termination without Cause.  Notwithstanding the
         previous two sentences, if the accelerated vesting of the
         option would make a change of control ineligible for pooling
         of interest accounting treatment under APB No. 16 and, but
         for such accelerated vesting provision, the change of
         control would otherwise qualify for such treatment, the
         Employee shall receive a replacement or substitute stock
         option issued by the surviving or acquiring corporation."

    2.   Paragraph 6 of the Employment Agreement is hereby amended and
restated in its entirety to read as follows:

         "6.  Severance

                   (a)  If the Corporation terminates this Agreement and
              Employee's employment after September 18, 1995 without Cause,
              then the Corporation shall pay to the Employee in a lump sum in
              cash within 30 days of the date of such termination an amount
              equal to the greater of (i) the amount determined by
              multiplying (A) the ratio determined by dividing the number of
              days remaining on such date until April 29, 1997 by 365 by (B)
              Employee's annual salary as determined on such termination date
              and (ii) Employee's annual salary as determined on such
              termination date. Payments to be provided hereunder shall in
              all respects be conditioned upon (i) the prior receipt by the
              Corporation from Employee of a general release of all claims of
              any nature whatsoever which Employee had, has or may have
              against the Corporation and related parties relating to his
              employment by the Corporation (other than his entitlement under
              any employee benefit plan or program sponsored by the
              Corporation in which he participated and under which he has
              accrued a benefit) or the termination thereof, such release to
              be in form and substance reasonably satisfactory to counsel for
              the Corporation, and (ii) continued compliance by Employee with
              the provisions of this Agreement that expressly survive
              termination.

                   (b)  Notwithstanding anything in this Agreement to the
              contrary, if it shall be determined that any payment or
              distribution by the Corporation to or for the benefit of
              Employee pursuant to the terms of this Agreement or otherwise
              (a "Payment") would constitute an "excess parachute payment"
              within the meaning of Section 280G of the Internal Revenue Code
              of 1986, as amended (the "Code"), as a result of a "Change in
              Control" of the Corporation as defined in Section 11 of the
              Corporation's 1996 Equity Compensation Plan and that it would
              be economically advantageous to the Company to reduce the
              Payment to avoid or reduce the taxation of excess parachute
              payments under Section 4999 of the Code, the aggregate present
              value of the amounts payable or distributable to or for the
              benefit of Employee pursuant to this Agreement (such payments
              or distributions pursuant to this Agreement are hereinafter
              referred to as "Agreement Payments") shall be reduced (but not
              below zero) to the Reduced Amount.  The "Reduced Amount" shall
              be an amount expressed in present value which maximizes the
              aggregate present value of Agreement Payments without causing
              any Payment to be subject to taxation under Section 4999 of the
              Code. For purposes of this Paragraph 5, present value shall be
              determined in accordance with Section 280G(d)(4) of the Code.
              The calculations under this Paragraph 6 shall be made as follows:

                                              2

<PAGE>

                        (i)  All determinations to be made under this
                   Paragraph 6 shall be made by the Corporation's independent
                   public accounting firm (the "Accounting Firm"), which firm
                   shall provide its determinations and any supporting
                   calculations to the Corporation and Employee within 10
                   days of the event that gives rise to the "excess parachute
                   payment."  Any such determination by the Accounting Firm
                   shall be binding upon the Corporation and Employee.
                   Employee shall in his sole discretion determine which and
                   how much of the Agreement Payments shall be eliminated or
                   reduced consistent with the requirements of this Paragraph
                   6(b). Within five days after Employee's determination, the
                   Corporation shall pay (or cause to be paid) or distribute
                   (or cause to be distributed) to or for the benefit of
                   Employee such amounts as are then due to Employee under
                   this Agreement.

                        (ii) As a result of the uncertainty in the
                   application of Section 280G of the Code at the time of the
                   initial determination by the Accounting Firm hereunder, it
                   is possible that Agreement Payments will have been made by
                   the Corporation which should not have been made
                   ("Overpayment") or that additional Agreement Payments
                   which have not been made by the Corporation could have
                   been made ("Underpayment"), in each case, consistent with
                   the calculations required to be made hereunder.  Within
                   two years after the event that gives rise to the "excess
                   parachute payment," the Accounting Firm shall review the
                   determination made by it pursuant to the preceding
                   paragraph.  If the Accounting Firm determines that an
                   Overpayment has been made, any such Overpayment shall be
                   treated for all purposes as a loan to Employee which
                   Employee shall repay to the Corporation, together with
                   interest at the applicable Federal rate provided for in
                   Section 7872(f)(2) of the Code (the "Federal Rate");
                   provided, however, that no amount shall be payable by
                   Employee to the Corporation if and to the extent such
                   payment would not reduce the amount which is subject to
                   taxation under Section 4999 of the Code.  In the event
                   that the Accounting Firm determines that an Underpayment
                   has occurred, any such Underpayment shall be promptly paid
                   by the Corporation to or for the benefit of Employee,
                   together with interest at the Federal Rate.

                        (iii)     All of the fees and expenses of the
                   Accounting Firm in performing the determinations referred
                   to in subsections (i) and (ii) above shall be borne solely
                   by the Corporation.  The Corporation agrees to indemnify
                   and hold harmless the Accounting Firm from any and all
                   claims, damages and expenses resulting from or relating to
                   its determinations pursuant to subsections (i) and (ii)
                   above, except for claims, damages or expenses resulting
                   from the  gross negligence or willful misconduct of the
                   Accounting Firm.

                        (iv) The limitations of this Paragraph 6(b) shall
                   only apply if payments under this Agreement are subject to
                   Section 280G at the time of the Change of Control.

                   (c)  Any payment provided for in Paragraph 6(a) above
              shall end upon Employee's obtaining other employment or
              full-time consulting work (defined as at least 30 hours per
              week) of any kind and shall be in full satisfaction of all
              claims for wages Employee may have against the Corporation as a
              result of such termination of this Agreement and his employment.

   3.   All references to "this Agreement" in the Employment Agreement shall
refer to the Employment Agreement as amended by this Amendment.
