made, that is all the Books and Manuscripts, according to the Titles whereunto they belong, are to bee ranked in an order most easie and obvious to bee found, which I think is that of Sciences and Languages; when first all the Books are divided into their subjectam materiam whereof they Treat, and then everie kinde of matter subdivided into their several Languages:  And as the Catalogue should bee so made, that it may alwaies bee augmented as the stock doth increas; so the place in the Librarie must bee left open for the increas of the number of Books in their proper Seats, and in the Printed Catalogue, a Reference is to bee made to the place where the Books are to bee found in their Shelvs or repositories.  When the stock is thus known and fitted to bee exposed to the view of the Learned World, Then the waie of Trading with it, both at home and abroad, is to bee laid to heart both for the increas of the stock, and for the improvement of it to use.  For the increas of the stock both at home and abroad, correspondencie should bee held with those that are eminent in everie Science, to Trade with them for their profit, that what they want and wee have, they may receiv upon condition, that what they have and wee want, they should impart in that facultie where their eminencie doth lie; As for such as are at home eminent in anie kinde, becaus they may com by Native right to have use of the Librarie-Treasure, they are to bee Traded withal in another waie, viz. that the things which are gained from abroad, which as yet are not made common, and put to publick use should bee promised and imparted to them for the increas of their private stock of knowledg, to the end that what they have peculiar, may also bee given in for a requital, so that the particularities of gifts at home and abroad, are to meet as in a Center in the hand of the Librarie-keeper, and hee is to Trade with the one by the other, to caus them to multiplie the publick stock, whereof hee is a Treasurer and Factor.

Thus hee should Trade with those that are at home and abroad out of the Universitie, and with those that are within the Universitie, hee should have acquaintance to know all that are of anie parts, and how their vein of Learning doth lie, to supplie helps unto them in their faculties from without and from within the Nation, to put them upon the keeping of correspondencie with men of their own strain, for the beating out of matters not yet elaborated in Sciences; so that they may bee as his Assistants and subordinate Factors in his Trade and in their own for gaining of knowledg:  Now becaus in all publick Agencies, it is fit that som inspection should bee had over those that are intrusted therewith, therefore in this Factorie and Trade for the increas of Learning, som tie should bee upon those Librarie-keepers to oblige them to carefulness.
