CONSERVATION: PHOTOCOPYING REPLACEMENT PAGES.
Photocopied pages can be used in the repair of library materials when:
- Pages are missing - In this case, another copy of the item needs to be borrowed through Interlibrary Loan, providing the library does not own a duplicate copy (including microfilm). If it is not possible to acquire a duplicate original, facsimilies of the missing pages can be obtained.
- Pages are damaged - When pages are badly damaged a photocopied replacement can be made of the original. The damaged page can be removed and copied, with the copy tipped in.
- Odd sized or multiple erratta - Erratta are printed in such a way that it is deemed better to copy the original and separate the entries for tip-in in the appropriate places in the publication.
Photocopies for repair on items for the libraries' collections should be made on archival paper. A supply is kept in the Conservation Unit.
When photocopies are being used to replace damaged or missing pages they should be copied to replicate the form of the pages being replaced, e.g. if a leaf with printing on both sides has been torn out, then the replacement leaf would have the missing pages printed on both sides, just like the original. Ads, if containing a page number, should also be reproduced.
Replacement page photocopies from other libraries should themselves be photocopied to archival paper before being tipped-in. Prior to photocopying, trim any extraneous black areas, such as those created when the copier copies beyond the original sheet.
When reproducing entire works, single sided copies can be used in place of double-sided when the work is 25 pages or less if this makes the task easier. Works over 25 pages should be double sided.
SCOPE
These procedures apply to general collections materials routed through the Conservation Unit. Special Collections materials, and pre 1850 imprints are handled under separate procedures.
PROCEDURE FOR DOUBLE SIDED PHOTOCOPY
The aim when making double sided photocopies is to have margins like the original on the top and outside edge of the page and to have the excess margin on the bottom and binding edge to make binding easier. The text area on both sides of the page should be aligned with each other. Also, check how the copier to be used orients its scanning area. Most copiers scan from the top left corner of the palette or from the center of the left side of the palette. This is important to know when determining the point from which top margin of the page is measured.
- Make sure the copier is set at 100% and double sided copies.
- Place the first page of the original on the copier palette so that the desired margin width is between the text area and top of the scanning area and the LEFT side of the pallette. Copy
- Place the second page of the original on the pallette with the desired margin between the top of the scanning area and the RIGHT side of the SCANNING AREA. The latter is determined by the size of the page being copied to. For example, if the size of the page being copied to is 8 1/2 x 11, the right margin would need to be measured from a point 8 1/2 inches from the left side of the palette, whereas copying to an 11 x 17 would mean the marging would be measured from a point 17 inches from the left left side of the palette. Copy.
- Check to be sure the text areas on both sides of the photocopy are reasonably aligned and that the margins are satisfactory.
Some practice may be necessary to produce satisfactory results, but when done properly, the result is a clean reproduction that needs very little trimming before tipping-in.
