It is advisable to mount all maps on some kind of cloth. It is best to have this done by a regular binder, but it may be done in the library if there is sufficient room.
If the map is to go on rollers, a piece of cotton cloth is tacked to a large table, the top of the cloth pasted, and the map placed on top, back down, all wrinkles having been removed. Millboards or strawboards are then placed on the map and weights placed on top until it is dry. This may take some time, after which it may be tacked to the rollers.
If it is a folding map or chart, it may be necessary to cut the map into sections before mounting. When mounted there will be one-eighth of an inch space between sections, so that the map itself will not be defaced through constant folding. The mounting of such maps is a difficult task and should be done only by an expert.
RECASING BOOKS
1. Remove book from the cover; cut out old super from the back of the cover; thoroughly clean the back of the book of super and glue without injuring the backs of the signatures. Lift the lining-paper from the back and front boards of the cover and remove the old super. Scrape with a knife the glue which does not come off with the super. If the back of the book seems to be much thicker than the fore edge, pound down with a backing-hammer.
2. Cut strips of muslin (or canton flannel) a little shorter than the height of the book, wide enough to cover the back and to extend over the boards 1-1/4 inches on each side.
3. Cut enough flexible glue to fill a double-boiler glue pot half full when dissolved. When the water comes to a boil the glue, which must be used hot to get good results, will generally be ready to use. If it is still too thick, add a little hot water to thin it.
4. Turn back the lining paper on front and back covers, spread the glue on the inside of the back of the cover and on the boards where the lining has been turned back.
5. Put the strip of muslin in the place just glued; then rub down the lining paper over the muslin.
6. Even up the book by tapping it on the table so that no leaves will project at the top, bottom or front.
