"Reader, if haply thou art blessed with a moderate collection, be shy of showing it; or if thy heart overfloweth to lend them, lend thy books; but let it be to such a one as S.T.C. - he will return them (generally anticipating the time appointed) with usury; enriched with annotations, tripling their value. I have had experience. Many are these precious MSS. of his - (in matter oftentimes, and almost in quantity not unfrequently, vying with the originals) - in no very clerkly hand - legible in my Daniel; in old Burton; in Sir Thomas Browne; and those abstruser cogitations of the Greville, now, alas! wandering in Pagan lands - I counsel thee, shut not thy heart, nor thy library, against S.T.C."

- Charles Lamb, "The Two Races of Men", December 1820. S.T.C. is of course his childhood friend Coleridge.
