This document provides guidance for recording seal matrices on the Portable Antiquities Scheme database. It discusses recording principles, terminology, documentation standards, and search techniques. Key points include using consistent terminology like "SEAL MATRIX" not just "SEAL"; documenting material, shape, size, decoration, and parallels; and searching by description text as well as filters. Photographs should have good lighting and projected views. The document aims to improve the quality and consistency of records.

2. Recording principles for the PAS database
The record replaces the object itself, just as a context
record replaces a dug-away archaeological context
The record must give enough evidence to allow the
reader to mentally re-identify the object, just as a well-
published archaeological site allows the reader to
mentally re-excavate it
The record must be consistent with other records, so
that we can be sure of retrieving every record that we
need, even from a really giant database
6. Seal: A piece of wax, lead, paper etc, with a
stamped design, attached to a document as
a guarantee of authenticity.
Seal matrix: The object used to make
impressions in wax as seals.

One to give to John Cherry to thank him for all his
help over the years
One more just in case

42. Photographing seal matrices
make the lighting as good as possible
light and photograph the impression separately if
necessary
check that the projection is correct
check that the images are the same size

46. IOW-54F605
Basic set of views
projected correctly
plus a flipped
horizontal version
(mirror-image)
and the photo of
the impression
Dont include just the flipped image without comment, as we
might think that the matrix was carved backwards.
47. How to search easily for seal matrices
start with words from the description field
in the simple search box
then filter by object type (SEAL MATRIX)
and period (EARLY MEDIEVAL)
add other filters e.g. county, material
