Condition
I am not a professional grader, so the following is my own simple classification, intended to supplement the photos of the item for sale.
The list of faults is probably not exhaustive, and is only intended to give an indication of books' overall condition.
Message me with any specific questions about condition and I will answer as best I can.
All Books...
...are complete and structurally intact, with content unobscured.
There are little (staple?) holes near or at outside page-edges, that are common in this type of publication.
Grade 1 (best)
Book(s) tanned, with fairly minor shelf wear, marks / foxing and corner creases.
Grade 2 (average)
Wear, marks, foxing & creases stronger or more widespread.
Binding staple rusty, with staining or damage to surrounding paper (in the margin/gutter).
Minor spine wear may be present.
A newsagent may have written the original purchaser's name on the front cover.
Grade 3 (lowest)
As above plus...
Spine wear may be more extensive and binding loose (but still intact).Creasing & marks may be more extensive or noticable and there could be small rips - usually to page or cover edges.
This book is in grade 2, just; the cover is worn and has some creases (as do some page corners); internally there is sporadic foxing; hwoever, the binding is still fairly strong.
