        <ExplanationTxt>The American Philosophical Society has certain committees that areresponsible for the selection of individuals receiving disbursementsin furtherance of the exempt programs. An application for a grant mustbe submitted either electronically or on typewritten forms provided for that purpose.Awards are made by the Society's Committees in accordancewith the following principles: 1. Grants are intended to assist investigators by providing forcosts of research work, such as the collection of scientific andliterary materials; preparation of photographs, microfilms, and otherrecords; purchases of supplies; necessary travel; and other incidentalexpenses of research. 2. Grants are not made toward the payment of salaries of members ofthe staff of an educational or scientific institution. Grants may notinclude institutional overhead. When a grant is made to a member of aninstitution to assist him or her in research of scholarly writings, it isexpected that the institution will cooperate in facilitating thework. 3. Grants are not made for: (a) salaries, fellowships, scholarships,or other projects involving personal expenses over long periods; (b)subsidies for publication; (c) usual or permanent equipment for theinstitution involved (but may be made for special apparatus needed inthe proposed research); (d) travel to meetings; (e) expense of grantee's family. 4. Support of a long-continuing project is not undertaken, except inits initial stage. 5. No recipient of a grant shall thereby become an employee of theSociety.The written agreement with the grantee's sets forth the specificobjectives of the grant and requires each recipient to file a writtenreport with the Society.In the formal notification sent to all recipients of grants there is arequest that credit be given to the Society in the publication of worksupported by such grants and that a copy of each publication be sent to the Society. To this has been added another statement that the Committee on Publications would appreciate an opportunity to consider publication of a manuscript, but there is no obligation that such a paper be published by the Society.</ExplanationTxt>

        <FormAndLineReferenceDesc>Grantmaker's Description of How Grants are Used</FormAndLineReferenceDesc>
        <ExplanationTxt>The American Philosophical Society has certain committees that areresponsible for the selection of individuals receiving disbursementsin furtherance of the exempt programs. An application for a grant mustbe submitted either electronically or on typewritten forms provided for that purpose.Awards are made by the Society's Committees in accordancewith the following principles: 1. Grants are intended to assist investigators by providing forcosts of research work, such as the collection of scientific andliterary materials; preparation of photographs, microfilms, and otherrecords; purchases of supplies; necessary travel; and other incidentalexpenses of research. 2. Grants are not made toward the payment of salaries of members ofthe staff of an educational or scientific institution. Grants may notinclude institutional overhead. When a grant is made to a member of aninstitution to assist him or her in research of scholarly writings, it is expected that the institution will cooperate in facilitating thework. 3. Grants are not made for: (a) salaries, fellowships, scholarships,or other projects involving personal expenses over long periods; (b)subsidies for publication; (c) usual or permanent equipment for theinstitution involved (but may be made for special apparatus needed inthe proposed research); (d) travel to meetings; (e) expense of grantee's family. 4. Support of a long-continuing project is not undertaken, except inits initial stage. 5. No recipient of a grant shall thereby become an employee of theSociety.The written agreement with each grantee sets forth the specificobjectives of the grant and requires each recipient to file a writtenreport with the Society.In the formal notification sent to all recipients of grants there is arequest that credit be given to the Society in the publication of worksupported by such grants and that a copy of each publication be sent to the Society. To this has been added another statementthat the Committee on Publications would appreciate an opportunity toconsider publication of a manuscript, but there is no obligation that such a paper be published by the Society.</ExplanationTxt>

        <ExplanationTxt>On advice of counsel, we have removed from the Laws the detailed procedures for the classes, the election of members, and the lengthy description of our committees and their working procedures. The version we are submitting for approval is thus significantly shorter than its predecessor. These materials will in the future be part of a new document called Regulations, which will be adopted by vote of Council and will be more readily amended as operational details evolve. The Laws, however, will remain subject to revision only by a vote of the Members (as state law provides). Apart from this major alteration, the significant areas of change in the Laws are as follows:1. Language from Pennsylvania law has been inserted into a considerable number of articles to conform to the current state of statutes. This language is mandatory and not subject to change by us. The most important such new language is in Chapter II, Article 9, Reserved Powers of Members. 2. Pennsylvania requires that committees be either governance committees, strictly defined as capable of acting on behalf of the Society, or advisory committees, of which the actions require ratification by Council. We have kept in the Laws only one governance committee, the Executive Committee of Council. All others are advisory and will be described in the Regulations. They can in fact take decisions within policies approved by the Council, for example in awarding research grants or fellowships, in selecting candidates for the annual elections, and in accepting acquisitions for the Museum. But they cannot establish policies without approval by Council. This is an important change in how we have operated, but we believe it can be implemented without disruption. 3. Just as we changed the Librarians official title recently to Director of the Library &amp; Museum (in large part to recognize the union of those two departments), we recommend using the title Chief Executive officer to make the nature of the position more recognizable in the world at large, and retitling the Financial Officer as the Director of Finance and Administration/Chief Financial Officer for similar reasons and to make the scope of this position clearer.4. We have recommended allowing International Members to nominate persons for membership. Such nominations remain subject to the decision of the Class Committees whether to have names go forward onto the first or second ballot, and International Members remain unable to vote in elections. 5. On advice of counsel, the provision for continued service on Council of past presidents has been eliminated (Chapter VI, Article 1). 6. The Curator of Art and Material Culture is now to be elected by the Members like other officers. The Curator of the Jefferson Garden will remain a presidential appointment but not serve on the Council. We have provided in the Regulations for a new Committee on Compensation, something we have lacked until now, with an annual duty of recommending the compensation for the Chief Executive Officer and a periodic one of reviewing the entire compensation structure of the Societys staff.</ExplanationTxt>
