Talk:BPG Atlases, Foldouts, and Guarded Structures

Currently, this talk page is a staging ground for text that will be added to the main page after my AIC presentation on May 18, 2021. Please feel free to also use this page to add your suggestions for improvement to the main page.--Kkelly (talk) 16:57, 6 April 2021 (UTC)

Mending

Some suggestions for mending offered by Pamela Spitzmueller are to apply mends flat but let them dry in a supported 90 degree angle, mend over-under, use grain-short mending strips, or leave tears open at fold intersections (1996).

Resewing/Rebinding

Paul Banks describes paring the edges of thick Japanese paper guards with a leather paring machine (Banks 1972).

Paper options for guards of uniform thickness: Two recent articles on rebinding atlases offer some options: 115 gsm handmade paper (Akbar Natural, Griffin Mill) for new guards for parchment bifolios (Bainbridge 2012), and xxx for new guards for thick paper bifolios (Albro et all 2012).

Other suggested changes

• remember to add updated definitions to BPG glossary.
• Add diagrams from my workshop.
• Add Tanner citation
• consider "spending a bit of time in the history section talking about the process of printing and hand-coloring more generally. If there was a little bit more information about the production of the maps, a discussion of verdigris might feel less out of place (KP)."

Consider adding this: Nancy Purinton (2003) A Historical Map-Printing Technique: Wax Engraving, Journal of the American Institute for Conservation, 42:3, 419-424, DOI: 10.1179/019713603806112688 --Kkelly (talk) 21:40, 5 October 2021 (UTC)

Compensation guard

“A thickness of linen or paper ... bound into a volume to compensate for the thickness of folded maps, charts or other bulky material within the text block,” (Roberts and Etherington 1982); also called a compensating guard (The Language of Bindings Thesaurus).

Compensation stub

Similar to a compensation guard, but consisting of an unfolded strip of paper or board. (definition derived from Ligatus use of the term “stub” and used in this sense in the 1962 GPO manual; Wootton, Boone, and Robb 2000; and Brown 2000). This can also be used to describe the smaller part of a stiff-board page with a secondary hinge (Brown 2000).

Concertina guard

Concertina guard: “A type of guard used in conservation binding. It is made of good quality paper (generally Japanese copying paper) and is used so that the adhesive applied to the spine does not come into direct contact with the sections. The depth of each fold does not normally exceed 1/8 to 3/16 inch.” (Roberts and Etherington 1982). (See also “concertina guard” in Horton 2000 and “zig-zag guard” in Roberts and Etherington 1982)

Full apron

An apron of extended length that allows a foldout map to be fully visible when a book is closed. This term is somewhat confusingly described in the sources listed below. Greenfield uses the term “full apron” to describe the combined apron and map of this type and “throw out” as another term for “foldout” (Greenfield 1998, 32 and 29). Roberts and Etherington use the term “throw out” to describe both this concept of a foldout fully visible when the book is closed as well as the more general concept of “foldout”.

Gatefold

“An illustration, map, or other leaf larger in one dimension than the other leaves of the publication and which consequently must be folded, usually at the fore edge or head, to make it the same size as the other leaves” (Roberts and Etherington 1982).

Guard

“A strip of cloth or paper wrapped around a folio at its fold for one of two purposes: to strengthen it, as in the case of an endleaf folio, or to add thickness at the gutter to match the thickness of items mounted on the leaves,” (Horton 2000, 23).

Hinge

A flexible strip of paper or cloth used to attach a leaf to another leaf, guard, or stub (definitions in both Horton 2000 and Roberts and Etherington approach this definition, but are not clear)

Extension guards

“Strips of sheet material (most often paper) tipped to the spine edges of individual leaves or bifolia which can then be folded, either individually or in groups (see bookbinder's gatherings), and sewn through. Guards were frequently used to hold the folds of folded plates or maps at distance from the spine of the bookblock, to allow them to be opened flat and not 'lost' in the gutter. Leaves attached to a bookblock in this manner are referred to as guarded,” (The Language of Bindings Thesaurus). In contrast to a leaf guard, these are longer and generally used for folded materials.

Leaf guards

“Strips of paper to which single leaves, or single bifolia, especially with maps and engravings on them, and which needed to be secured at a small distance from the spine edge of the bookblock, were adhered along their spine edges.” (The Language of Bindings Thesaurus). Shorter than an extension guard and generally used for single leaves or bifolia.

Separate stubs

“The single stubs created by folding pieces of sheet material along one edge. Separate stubs will be created by hook or outside-hook endleaves made from two or more separate pieces of sheet material, as opposed to the folded stub created by a single sheet folded twice to create the hook or stub, but will also be found where single leaves are folded along their spine edges to be incorporated into gatherings in bookblocks,” (The Language of Bindings Thesaurus). Compare with folded stub.

Folded stubs

“Stubs composed of two elements which are joined together by a fold along their outer edges. These are frequently found on hook-type and outside-hook endleaves,” (The Language of Bindings Thesaurus). Compare with separate stubs.

Tipping

The process of attaching a leaf or a single bifolium to another leaf or stub by means of a line of adhesive along its spine edge. This technique was often used for unsewn endleaves and inserted plates into a textblock (The Language of Bindings Thesaurus). Compare with hinge.
