<br />g) Covers may be opened to support the volume. <br /> <br />h) Aluminum foil may be placed between the cover and the end leaf to prevent <br />staining from the binding dyes. <br /> <br />i) When most of the water has drained, proceed as for "Damp Volumes", below. <br /> <br />1. Damp Volumes <br /> <br />j) Very carefully open the book (not more than a 300 angle). <br /> <br />k) Keep the volume in an upright position. <br /> <br />I) Place interleaving sheets at intervals of twenty-five leaves (fifty pages), unless <br />they will distort the volume. <br /> <br />m) Change interleaving frequently. Do NOT reuse unless the sheets are being <br />impregnated with fungicide. Ortho-Phenyl Phenol (O-PP) is recommended. Mix <br />one pound of O-PP to one gallon of acetone or ethanol (do not use methanol, <br />as it will cause inks to bleed). Safety equipment (mask, eye goggles and rubber <br />gloves should be worn when preparing and using this solution. <br /> <br />1. Slightly Damp Volumes/Volumes with Only Wet Edges <br /> <br />n) Stand volume on its head and fan open slightly. Paperback books may support <br />each other with a barrier between them or they may be wedged with Styrofoam <br />pieces. Position volume in the path of circulating air. <br /> <br />0) When almost dry, lay the volumes flat and place weights (NOT other drying <br />books) on them to minimize distortion. Do not stack wet volumes. <br /> <br />p) Lightweight volumes (less than six pounds) may be hung on lines to dry. <br /> <br />1. Use monofilament nylon lines, not more than 1 /32" diameter, not more than <br />five or six feet long, spaced approximately one-half inch apart. <br /> <br />2. Do NOT line-dry a saturated volume as the monofilament will cut through the <br />wet paper. <br /> <br />3. Volumes With Coated Stock Paper <br /> <br />a) Wet coated stock paper should be handled with care, as the print will <br />slide off the wet page if it is rubbed. DO NOT allow wet books with <br />coated stock paper to dry in a closed state as the pages will <br />permanently bond together. Almost all attempts to separate stuck <br />pages by rewetting them have failed. Vacuum freeze-drying of <br />coated stock volumes is rarely successful. Keep volumes submerged <br />until the pages can be separated. The only chance of saving such <br />materials is to interleave every page and air dry. <br /> <br />Page 27 <br />
